Metro Beach banding report - September 25 & 26, 2009

After an absence of 7 days from the area, perhaps it is not surprising that again a number of new arrivals were recorded. Among these, White-throated Sparrows and Hermit Thrushes arrived in big numbers after only a few White-throats a week ago. Strong or even moderate cold fronts continue to avoid southern Michigan, so I am very glad that nearly 250 individuals were banded on these two days, and with such good diversity represented.

Banding highlights from Friday, September 25 included a Ruby-throated Hummingbird, possibly the last one of the season. The almost complete lack of Jewelweed (Impatiens capensis) flowers in the banding area has clearly had an impact. Normally there would be hundreds of plants with dozens of flowers on each plant. But this year the deer have so completely devastated the Jewelweed that perhaps at most one plant in five has a single flower on it. The first Blue-headed Vireos (3) of the fall season were captured today.

Winter Wrens were first detected last week, but the first ones were banded today.

Hermit Thrushes made their first appearance today as well, with a good total of 9 banded.

Hatch-year Hermit Thrush

Somewhat surprising was the capture of a Wood Thrush. They've been caught later here, but any time after September 20 is unexpected.

The first Orange-crowned Warbler was captured today, just about on time for the species. Often there are reports of this species in early September and even late August. No less an authority than Jon Dunn has suggested that any claim of Orange-crowned Warbler in the Great Lakes earlier than about September 20 should be carefully scrutinized. Many observers may not realize how green juvenile Tennessee Warblers can be in the fall, and neglect to check the single best field mark, the color of the undertail coverts. While they can be pale yellowish (but most often bright white) in Tennessee Warbler, they are bright lemon yellow in Orange-crowned Warbler. Both species were captured today, and photos below may help resolve some of this confusion. Also, compare the photo of the hatch-year Tennessee Warbler with those of the second-year females posted earlier this month.

As noted, White-throated Sparrows arrived in force, with the handsome individual in the photo below only one of 32 banded today.

A species we don't catch very often, as they tend to feed in areas with more open spaces, is White-crowned Sparrow, so this individual was a little unusual.

And an unexpected species, as we don't catch very many and they don't often arrive this early, was Dark-eyed Junco.

Interesting birds observed today but not banded included 2 Cooper's Hawks, 2 Red-tailed Hawks, and a Veery calling before dawn. A couple small groups of Golden-crowned Kinglets signalled their first arrival for the fall.

Banding highlights from Saturday, September 26 included species that aren't banded here very often. A Yellow-bellied Sapsucker was only the second one banded here since 2004, and only the 8th one since 1989.

Eastern Phoebes aren't banded as often in the fall as they are in spring, and the one captured today was a little early for the first of season.

Other flycatchers captured today, both a little later than normal, were single Yellow-bellied and Least Flycatchers. Additional Winter Wrens, Hermit Thrushes, and Orange-crowned Warblers added to yesterday's totals. A flock of American Robins in the Upland Nets was unusual for so late in September in the banding area; usually they abandon the area by the end of August. A single Yellow-rumped Warbler was the first of the season, hopefully the first of many more to come.

A single Wilson's Warbler was a little bit late, and Lincoln's Sparrows were clearly peaking with 4 banded today. Another Dark-eyed Junco was as unexpected today as were the 3 banded yesterday. After just having discussed the diminishing possibility of catching a Rose-breasted Grosbeak with one of the volunteers, there was one out in the Field Nets not more than an hour later!

With a powerful bill like that, there's NO WAY I'm going to hold it in the "photographer's grip" just for a decent photo on the blog. I don't need bloody fingers from that bite! Here I'm holding it in the "banders grip" which is safe and gentle for both the bird and the bander.

Interesting birds observed today but not banded included calling Great Horned Owls before dawn, a Cooper's Hawk, at least one other Yellow-bellied Sapsucker that was heard while banding another, and a briefly singing Marsh Wren in the dying Phragmites stand near the Field Nets. Golden-crowned Kinglets were in the banding area again today, but not captured. Soon we'll have many!

Many thanks to the volunteers who made banding possible on these two days: John Bieganowski, Andrea Charlebois, Chris Charlebois, Jacob Charlebois, Amanda Grimm, Dave Lancaster, Jennifer Philpot-Munson, and Tom Schlack.
