Florida Trip - Days 6-8

Day 6 - Wednesday, December 10, 2008

We started the morning at Ding Darling National Wildlife Refuge on Sanibel Island, where we took the 5-mile loop road as soon as they opened at 7:30 a.m. There was one area with a LOT of shorebirds of many species, including Red Knot and Marbled Godwit among the more numerous dowitchers and peeps. Unlike our visit here in 1978, there were almost no ducks (thousands of American Wigeon, Northern Pintail, and Blue-winged Teal before) and very few American Coots (10,000+ before). We saw only a handful of wigeon, about ten teal, and a couple hundred coots. Perhaps they hadn't arrived yet from the north? Of course, we were here in November in 1978 which may have made a difference. The numbers of waterbirds was lower too, but we did manage to see most of the major species including:

Reddish Egret

Snowy Egret

White Ibis

From here we headed south through Naples then east towards the Everglades. Our next stop was the Fakahatchee Strand State Park where we intended to walk a short boardwalk, then drive a scenic road. Unfortunately, we found out that the road wasn't in great shape so we'll have to go there some other time. This area is better known among orchid enthusiasts than it is among birders. Several rare orchids are known only from this area, and a few species have not been seen in many years, or the exact location where they were found originally has been lost. Much of this is due to over collecting, but some is due to environmental issues, such as a period of freezing in the 1980s. Looking out at the habitat from the boardwalk, it isn't too hard to figure out why some of these often inconspicuous plants have vanished for years, decades, or even forever.

We saw more Wood Storks in this part of Florida than elsewhere.

Heading east, we stopped at various locations within the Big Cypress Reserve where waterbirds were very common, including especially American Anhingas, in the ditches.

At a new Visitors Center (well, apparently new since our last trip through this part of Florida in 1988), another Anhinga allowed very close approach.

And American Alligators were very abuntant also, including some large ones that were perhaps 10-feet long.

Near the boundary of Everglades National Park we found a Snail Kite at the expected locale near the Miccosukee Restaurant, but it only allowed for a few brief photos. From here we headed northward to the Atlantic Coast where we stopped near Melbourne, Florida for the night.

Day 7 - Thursday, December 11, 2008

We were concerned about getting home on or before Saturday, so we got up very early and drove 200 miles north to Jacksonville, arriving at the Fort Clinch State Park. Here, we hoped to see a few species difficult or impossible to find elsewhere in Florida. These included Purple Sandpiper which would be on the jetty, and scoters and Northern Gannets which would be offshore. It turned out that the pier was closed so views of the jetty were very restricted, and no Purple Sandpipers were in evidence.

It was overcast, windy, and threatening to rain. Offshore there were virtually no waterfowl of any kind, but a couple of immature Northern Gannets did oblige with distant views. On the beach here was a fairly large flock of Laughing, Ring-billed, and Herring Gulls (two Bonaparte's), Royal Terns, and Black Skimmers.

The wind kept putting the birds up, and they had to keep resettling themselves on the beach.

As we left this park around 10:30 a.m. it started raining. By the time we got back to the freeway it was torrential. We drove north into Georgia and, despite the rain, headed east to Jekyll Island. Most of the species we were hoping to add to our Georgia list were waterbirds that would likely still be active despite the rain, but most land birds were hunkered down waiting for the storms to pass. We did succeed in finding may shorebirds, gulls, terns, both Brown and White Pelican, and Northern Gannet. The rain never let up, but was somewhat lighter at times, so it would have been foolhardy to try to take photos. It is clear that during spring and fall migration, Jekyll Island would be a birder's paradise.

From here we continued north, and around 2 p.m. the rain was stopping and the sun was even starting to come out. Reports on the radio indicated that some areas had gotten 4-inches of rain with this storm, though apparently no tornados (watches were posted). We decided on one more stop, at the Harris Neck National Wildlife Refuge. We drove the 4-mile loop road here, finding a few birds but not a lot of water was visible from the road. We found a Nine-banded Armadillo, face down in pine needles, foraging along the roadside in one area of Longleaf Pine woodland. The pink scar on his/her rump is likely from a close encounter with a car.

And one of the last birds of the day was this fine Loggerhead Shrike perched right next to the road in the Refuge.

We then continued northward into South Carolina, mostly in the dark, stopping near Orangeburg for the night.

Day 8 - Friday, December 12, 2008

We decided not to get an extremely early start, as we had 800 miles to get home and it might be too difficult to do in a single day, depending on the weather we'd encounter. We started at 7 a.m., and the roads were quite clear all the way up into North Carolina and Tennessee. We had some very scenic views around the east and north sides of the Great Smoky Mountains caused by snow. Fortunately, most of the snow was above the level of the road. Northward into Kentucky, the temperatures really started dropping (it was 73 when we started), getting down to freezing pretty quickly. The roads remained clear, except for rush hour traffic around Cincinnati and Dayton, Ohio. We managed to make it all the way home by 9:30 p.m.

Florida Trip - Day 5

Tuesday, December 9, 2008

This morning we arrived at Honeymoon Island State Park about 15 minutes before they opened. We walked the Osprey Trail, which lived up to its name, with several nests and cooperative individuals along the trail. Part of the trail was closed due to an active Bald Eagle nest. We were rewarded with a couple low fly-bys of eagles, even though we didn't walk out to the end of the trail to see the nest.

We also found many land birds along this trail, including the first Prairie Warbler of the trip. The park is famous for shorebirds, sometimes with "thousands" present, we had to settle for dozens today (though there were many dozens of Royal Terns and Black Skimmers) since it was high tide. But, some of the shorebirds were fairly cooperative for photos, including:

Black-bellied Plover

Piping Plover

Snowy Plover

American Oystercatcher

From here we headed south to the Sarasota area, where we checked the Celery Fields which were supposed to have a few Black-bellied Whistling-Ducks. We succeeded in finding them, though only distantly in the scope, along with many other waterbirds including Glossy Ibis, Wood Stork, lots of coots, Lesser Scaup, and a couple Mottled Ducks. One of the more unexpected birds in this area was a pair of Monk Parakeets, one of which posed nicely on the power lines for photos.

Next, it was on to the Oscar Scherer State Park near the town of Osprey, where we birded in the sandy pine and oak scrub.

One of the first things we saw here, after a couple species of butterflies, was quite a surprise. We found not one, but two different Gopher Tortoises, a lifer for us! The first one was quite shy and "sprinted" off into the brush when we got out of the car. The second one was much more tolerant, and allowed close approach.

Of course the key bird in this habitat is the Florida Scrub-Jay. Finding a family group was impossible on the Green Trail, but a short distance down the Yellow Trail they found us rather quickly, and as expected, tried to land on us! Two of the birds were color banded as part of ongoing research on this Threatened species, while two others were not banded.

With a 400mm lens on my camera, it took quite a bit of backing up to get more than just the bird's head in the frame, as in this shot below.

It was actually just as easy to photograph these birds with my "point-and-shoot" camera.

And this point-and-shoot shot was taken against the sky, but with fill flash, which the birds ignored.

Our last stop of the day was intended to be on Sanibel Island near Ft. Meyers at the Ding Darling National Wildlife Refuge. But, we were running out of daylight so decided to do that tomorrow morning, and stopped for the night at the south end of Ft. Meyers.

Florida Trip - Day 4

Monday, December 8, 2008

At sunrise we were entering St. Marks National Wildlife Refuge, and for the first time on the trip we encountered a more than a few waterbirds. We headed straight for the lighthouse to scan the Gulf of Mexico and saw some loons and grebes, as well as Oystercatchers and Brown Pelicans. It was surprising when a small group of American Goldfinches turned up with a Pine Siskin among them. This species is not on the bird checklist that is available here. Another siskin was at the Tower Trail restrooms, again with a group of goldfinches. More typical of Florida, we saw several American Anhingas (photo below) in the early morning cold (started at 32 degrees again today).

Many more familiar waterbirds were seen, including Lesser Scaup, Redheads, Canvasbacks, American Wigeons, Hooded Mergansers, American Coots, Pied-billed Grebes, and quite a few Belted Kingfishers, like the one below.

Heading east, we stopped at the Goethe State Forest to check the Longleaf Pine woodlands for Red-cockaded Woodpeckers and Brown-headed Nuthatches. We found the woodpecker nest trees, visible in the photo below marked by a white band near the base, but no woodpeckers. The nuthatches were more cooperative and allowed me to get sound recordings of their vocalizations.

And finally, a most interesting encounter. We encountered a baby of the possibly extinct Ivory-billed Woodpecker, as seen in the photo below.

Those familiar with James Tanner's study of the Ivory-billed Woodpecker from the 1930s will recognize my imitation of a photo in his book where he had two fledglings in his hat. This cute toy, which also gives accurate calls when squeezed, was available for sale at the St. Marks NWR gift shop. We stopped in Bayonet Point, Florida, for the night.

Florida Trip - Day 3

As we drove south out of Montgomery this morning, we saw our first signs of waterbirds with a small group of a dozen or so Great Blue Herons flying over the freeway. The temperature this morning was 32 degrees and all the vegetation was frosty though none of the water was frozen. We also saw a sign of the deep south, Spanish Moss draped all over the trees. We made our way into the Florida Panhandle, and drove around in the vicinity of the Choctawhatchee River, which is where there have been possible reports of Ivory-billed Woodpeckers recently. We didn't get so lucky, but did stand at a boat ramp that gave views off into the swamp. Even if the Ivory-bills no longer exist, standing in an area near where they once existed is still something I feel worthwhile doing.



From here we drove northeast to Florida Caverns State Park. We had information that the Georgia Blind Salamander was found here, so we thought we'd give it a try. Once there, they told us that it was in their cave system but only rarely was seen in the cave as the water table is usually too low. We tried our luck on the surface, finding one tiny Southeastern Slimy Salamander on a rock wall under some leaf litter, and this Green Anole (they're sold as "chamaeleons as they can change color) under a log.



From here we went back southeast to the Apalachicola National Forest where we had brief looks at two Red-cockaded Woodpeckers as they came in to roost for the night. No photos but I did manage to get a brief recording of their vocalizations. The temperature rose to 60 degrees today, we're definitely in Florida! We drove quite a ways in the dark to Medart, Florida for the night.

Florida Trip - Day 1 & 2

After having canceled two vacations this year, mainly due to the poor economy, we finally decided we could afford to get away for a few days and decided to drive to Florida and back, with no set itinerary.

Day 1, December 5, 2008

We left this morning at 7 a.m., with the temperature at 19 degrees. Today was mainly a travel day, so we didn't see too many birds other than the common roadside species including Red-tailed Hawks, American Kestrels, American Crows, European Starlings, and of course Rock Pigeons. Once we crossed into Kentucky, we soon saw a couple of Black Vultures, and the first Loggerhead Shrike of the trip was near Sonora on the way to Louisville, where we stopped for gas. Thanks to driving a hybrid, we only used $14 worth of gas to drive from Detroit to Louisville. We also started seeing what I consider a sure sign of being in "the south", evergreen balls of mistletoe in the trees. We drove south from Louisville and got a room in Cave City, then went into Mammoth Cave National Park. We asked about tours for tomorrow, and also asked about salamanders. One helpful park person suggested we walk to the Three Springs area where there was flowing water out of a hillside, where hopefully there would be Spring Salamanders. No luck. The temperature never went above 32 today.

Day 2, December 6, 2008

We drove around in Mammoth Cave National Park for a while before our tour started at 10:15, with the best bird seen being the flock of about 15 Wild Turkeys. We decided to take a 2-hour tour that would optimize the time we had available with seeing the most formations. Photography was difficult in the dim light, but I did manage a few decent photos. One of these is below.

Nancy and I like caves because of the formations, but also because of the various creatures that can be seen inside, including some of our favorites, salamanders. This time, we were lucky enough to see a single spider, and Cave Crickets, which really looked more like brown, blind, katydids.

After lunch, we continued driving south, through Tennessee and into Alabama, where we stopped near Montgomery for the night. Temperatures are warming up, as we started at 28 and ended at about 45.

Three Rufous Hummingbirds

After the main Ruby-throated Hummingbird banding season, I typically spend a lot of time (and miles) chasing down and banding other species in Michigan, Ohio, and northern Indiana. Reports typically come in during October and November, but sometimes as early as August and as late as December. Last year (2007) I banded a record four in Michigan, but significantly fewer (two) in Ohio and none in northern Indiana. In 2006 there were again only two in Ohio, one in Indiana and none in Michigan. Prior to this recent dip in numbers, 5-6 in Ohio was expected and at least two in northern Indiana. So far this year, I've banded three Rufous Hummingbirds, one in Ohio and two in Michigan. One other Rufous was banded in southwestern Ohio by Tim Tolford and one Rufous was banded in southern Indiana by Cathie Hutcheson. Here, I provide photos and brief details of the three Rufous Hummingbirds I've banded so far.

Adult female Rufous Hummingbird in Bexley, Franklin Co., OH

First Observed: mid-October 2008 (?), Last Observed: 5 December 2008+

On November 14, I arrived at the home of JoAnn LaMuth, where several local birders, and a reporter and photographer from the Columbus Dispatch had assembled. Now, 95% of the Rufous Hummingbirds I've banded have taken 5-10 minutes to enter the trap. This one took a full 2 1/2 hours! This allowed us to discuss many, many aspects of hummingbird biology, and birding, with the newspaper folks. About a minute before I was ready to quit, the bird arrived (5 hours after the last sighting) and went into the trap. Note in the photo below that she is missing quite a few feathers on her lower throat. This is something I associate with a minor mite infestation, but I can't say for sure what the cause might be on this bird.

The shapes and widths of the tail feathers are important criteria for identifying these birds. The second tail feather from the center on this bird was broken off on one side, and very slightly "notched" on the other side, which is characteristic of Rufous. The width of the outer tail feather was 3.63mm, which also is characteristically wide enough for Rufous.

Adult female Rufous Hummingbird in Shields, Saginaw Co., MI

First Observed: mid-October 2008 (?), Last Observed: 5 December 2008+

This bird, at the home of Bernie Coleman, was very cooperative, going into the trap within 10 minutes of my setting up the trap. She had a total of 17 iridescent gorget feathers, which is about typical of an adult female (ranging from 7-21).

Females are consistently entirely green above, from forehead to tail tip, with no rufous visible on the base of the central tail feathers.

The second tail feather of this female was more noticeably notched than the Ohio bird, and the outer tail feather was measured at 3.48 mm (it looks narrower in the photo below due to the angle I'm holding it at), wide enough to confirm Rufous. This bird also showed a molt pattern on the primaries that I've come to consider normal in this region, as 95% of them have shown it. The outer 4 primaries were old and all the inners were new and recently replaced.

Adult male Rufous Hummingbird in Holland, Ottawa Co., MI

First Observed: 7 November 2008, Last Observed: 5 December 2008+

It has been a while since I banded an adult male Rufous in the region. This bird was coming to the feeders of Nancy Gillis, who photographed it quite nicely, and who generously allowed me to come and band the bird on December 1. This bird was very anxious to go into the trap, and flew up before I had the door propped open. Within two minutes, he was in-hand being measured and photographed. He had the full gorget of an adult male, though the lighting did not allow the iridescent color to be seen.

The entirely rufous-brown back made the identification easy. Note the snow in the background, almost certainly not the first this adult has seen in its lifetime.

The pointed tail feathers without any white tips is also characteristic of an adult male. And, the second tail feather is described as "notched" in this species, but as the photo shows it appears more like a couple of bites have been taken out of it. Weird.

Whenever possible, I try to allow the homeowners to "release" their hummingbird. In the photo below, Nancy got a few seconds of "hand time" with her adult male Rufous, which bolted into a large tree in the yard and was back at the feeder (trap removed) within minutes.

Metro Beach Banding - Brief Summary of Fall 2008 Results

Banding was conducted for the 4th consecutive fall season at Metro Beach Metropark, Macomb County, Michigan, as part of a continuing long term migration monitoring project to assess changes in migrant status, and to reaffirm the value of this isolated habitat as a resting and refueling stop, as well as other more specific research objectives. Results will be compared with banding efforts conducted here by Ellie Cox from 1989-2001. Hopefully, this continued monitoring will help park management make informed decisions about habitat management and prevent any future attempts to develop this area. This data is also contributed to the continent-wide Landbird Monitoring Network of the Americas (LaMNA); www.klamathbird.org/lamna

Banding was conducted on 22 days between August 9 and November 1, with 13 nets open a total of 158 hours and 1891 net hours in an area ~175 meters (~200 yards) square (~3 hectares or ~8.3 acres). A total of 1841 birds of 77 species (records for both) was banded. A detailed summary will be posted sometime before the end of the year on my website at: http://www.amazilia.net/MetroBeachBanding/

Thank you to the many volunteers who made this research possible: Barb Adams, John Bieganowski, Russ Brown, Terri Chapdelaine, Chris Goulart, A'Monica Hubbard, Thierry Lach, Dave Lancaster, Harry Lau, Rose Lau, Tessa Lau, Frank Lautner, Lori Leighton, Bonita Olesen, Steve Olesen, Renee Render, Greg Scheffler, Tom Schlack, Michelle Serreyn, Joan Tisdale, Johanna Wielfaert.

Metro Beach Banding Results...so far

That this has been a very good fall for banding is certainly supported by the numbers. It is difficult to be brief, so I won't! The 133 birds banded on Saturday (Oct 11) brought the season's total to 1447, just short of the 1493 in fall 2006 and there are still three weeks to go! These two days were also the 4th and 5th banding days in a row with more than 100 birds banded! Also, the 6 new species for the season added on Saturday brought the fall total up to 72 species, the highest ever, spring or fall. Next highest species total is 67 for spring 1995 and fall 1990 & 1991. Many records have been broken for individual species as well. Record days of 7 Winter Wrens on Thursday (Oct 9) and 6 on Saturday brought the seasons total equal to the record of 14 in fall 2005, and we'll almost certainly band more before the end of the month. The 45 Yellow Warblers banded this fall (none recently) beats the previous fall record of 30 from 2007. The 49 Black-throated Blue Warblers so far this fall beats the previous records of 41 in fall 2006 and 23 in fall 1991. The 96 Common Yellowthroats this fall beats the previous records of 53 in spring 1997, 50 in fall 2007, and 42 in fall 1991.The 151 Song Sparrows so far this fall beats the previous records of 108 in fall 1991, 101 in fall 1990, and 100 in fall 2007. The 120 Swamp Sparrows so far this fall beats the previous records of 115 in spring 1997, 94 in spring 2007, 42 in fall 1994, and 36 in fall 2007. The 226 White-throated Sparrows so far this fall beats the previous records of 203 in fall 2006 and 160 in fall 1989. The 155 American Goldfinches banded so far this fall is much higher than the previous records of 67 in spring 2007, 46 in spring 1996, and 41 in fall 2007. Higher goldfinch numbers is all thanks to the thistle sock feeder placed inside the "U" of the Field Nets a couple weeks ago. It is quite clear that the Field Nets, added in 2006, have been very productive for all species using open wet habitats.

On Thursday (Oct 9) banding highlights included a Northern Flicker (the 6th for the season), a record of 7 Winter Wrens, and the second Orange-crowned Warbler of the fall. Interesting birds observed but not banded included a late Yellow-bellied Flycatcher, a Blue-headed Vireo, a Red-breasted Nuthatch, a Marsh Wren, single Magnolia and Blackpoll Warblers, and a Dark-eyed Junco.

On Saturday (Oct 11), in addition to a lot of birds (the nets had to be closed for a couple of hours in order to catch up), there were many banding highlights. The immature female Sharp-shinned Hawk was the first since 2005 and only the 4th one since 1989. The Philadelphia Vireo was the second since fall 2005 and only the third since spring 2004. By contrast, a total of 48 were banded between 1989 and 2000 (44 in fall). So, where are they these days? The Tufted Titmouse was only the 4th since 2004 and only the 11th since 1989. The Field Sparrow was the first in fall since 1991, the second since 2005, and only the 6th one since 1989. Also, the 3 Eastern Phoebes and 1 Blue-headed Vireo were the first of the fall, and the 3 White-crowned Sparrows were a good number. A single Common Yellowthroat was somewhat late. Interesting birds observed but not banded included several Mourning Doves in the banding area (but none captured), at least 4-6 Eastern Towhees in the banding area (none of those captured either!), and a Dark-eyed Junco.

Summer Hummer Banding

Reality has a way of altering good intentions. It was my intention to post about my hummingbird banding throughout the summer. The reality was that I had gotten a paying gig as a field biologist for the Michigan Breeding Bird Atlas which meant I was traveling up to Macomb and St. Clair counties in the pre-dawn darkness up to four days a week, and getting home around dinner time, and spending the evening transferring my data to the data cards. On the other days, I was able to band hummingbirds, but blogging just never made the priority list. I have a t-shirt that says "Life is simple: Eat, Sleep, Bird". Well, this Atlasing gig made the first one of those three possible while at the same time making the second one much more necessary! The upside was that I was able to bird/survey some interesting areas.

Over the summer I did manage to visit at least 20 of the 40+ banding sites that I normally visit. Despite the reduced coverage, I was able to band a total of 263 Ruby-throated Hummingbirds during June and July. This compares favorably with 265 in summer of 2007, 240 in summer of 2006, and 335 in summer 2005 (which included 117 banded in the Upper Peninsula). In addition to documenting the breeding populations, returning birds, longevity (including 3 birds that are now at least 6 years old), and breeding timing, there were other interesting observations from this summer. One of these included an adult female with a crossed bill.

At another locale, another adult female was showing several white feathers on her forehead. This is something I regularly encounter at the few sites were I band a lot of birds (50+ per season per locale). This plumage condition is called albinism, though sometimes when only a few feathers are involved it is called (inaccurately) "partial" albinism.

Another odd plumage condition is called Leucism, which is a fading of the pigment in the feathers. I captured this molting adult female, which the homeowner called "Gray Girl", which was a very pale grayish-green on the upperparts. Given that the iridescense of hummingbird feathers is due to microscopic structures, I'm not sure how the fading happens as there is no green pigment in bird feathers.

As summer comes to a close, the adult females signal that they're done fledging young by entering the next phase of their lives, where they molt all their body feathers prior to migrating south. Some of them can look pretty bedragled during this awkward phase of their life, like the adult female in the photo below.

Ruby-throated Hummingbird molt is not well documented in our region, and it is one major aspect of my research. Also, as July comes to a close, I begin anticipating the capture of the first hatch-year (young) of the summer. Although I've banded nestlings that have left the nest earlier, I've so far never banded a young hummer at a feeder before July 25. This year the first one was on August 1. Hatch year birds are in very fresh, pristine plumage which is quite a contrast to the molting adults.

My next good intention is to post the results of my "fall" banding, which will cover all hummingbird banding activity during August and September.

Where are all my hummingbirds?

Every year around this time, I get asked the same question. Where are all my hummingbirds? If I'm feeling silly, I answer "I don't have them!" But this can be a difficult question to answer seriously. Over the past few years that I've been giving talks on hummingbirds at many Audubon meetings, Nature Centers, garden clubs, and others, I have queried the audiences about this. On average, about 15-25% will raise their hands when asked "How many people have fewer hummingbirds than normal?" Then I ask "How many people have more?" Again, the number seems to be about 15-25%. And to the question "How many people have about the same?" the response is from about 50-60%. People who have the same or more rarely ask me why!

I began the Great Lakes HummerNet project, in part, so that I might understand the population cycles of Ruby-throated Hummingbirds in Michigan. Most bird species undergo population cycles, and I suspect that hummingbirds are no different. It also seems that centers of abundance may shift from year to year, so that for every location that has less, there is one that has more. This year, in my own yard, I had only seen a single adult male Ruby-throat at my feeders until the thunderstorms came through today when another male, and my first female of the year, was seen. This is extraordinarily late for my first female. And, some of the comments I've been receiving indicate that perhaps some of the declines are more serious than other years. There might be something going on. But, I don't have an answer on that yet.

I would appreciate it if you could share your story about hummingbird numbers this June by either posting your comment to this blog, or sending me an e-mail directly (amazilia1@comcast.net). Please provide your location as part of your story (Michigan locations only please). I'll compile the results in some manner and post something on it later. In the meantime, you might enjoy a photo taken last week by Bob Anderson, who feeds hummingbirds in Marenisco, Gogebic County, in the far western Upper Peninsula of Michigan. My best guess is that there are 65 hummingbirds in this photo, mostly males. If you're missing some hummingbirds this year, I don't have them, but maybe Bob does!
