Metro Beach banding station report - April 23 & 27, 2014

For the first time, every banding day in the month of April started out with temperatures in the 30s. The two banding days covered here did reach into the 50s by the time we closed the nets. Hopefully we'll see a warming trend soon! Only one banding day was possible the third week of April because that's all the volunteers I could convince to come out, so the first day of the next week is included here also. Overall, captures were rather low for the entire month of April. We'll see what happens once the warblers arrive.

Highlights of the 25 birds banded on Wednesday, April 23 included the third Northern Flicker of the spring, this one a male, as can be clearly seen by its black whisker.

The first swallow of the spring was captured today. But despite there being considerable Tree Swallow activity around the nest box near the Field Nets, the first swallow banded was a Northern Rough-winged.

Although they have been in the banding area for at least two weeks, the first Winter Wren of the spring was captured today. It could certainly be the last since very few have been banded in the first week of May here.

Not much of a highlight, but still a beautiful bird up close, was the European Starling; this one a male distinguished by the light blue at the base of its yellow bill. Normally I don't band starlings, but the previous bander here did, so to follow the protocol I band them here.

Interesting birds observed but not banded included a calling Pied-billed Grebe in the marsh to the north, calling Virginia Rails and Sora, an Eastern Phoebe, the lingering Louisiana Waterthrush, and a Rusty Blackbird.

Highlights of the 39 birds banded on Sunday, April 27 included the second swallow of the season, this time the expected Tree Swallow. In addition, another already banded Tree Swallow was captured, that one a male that had been banded in spring of 2013.

None were heard singing in the banding area today, or any day prior, so it was nice to have the season's first House Wren today as a sign that the migration was progressing...slowly.

Overwintering White-throated Sparrows are sometimes caught in early April. That did not happen this year, but they are almost always quite worn and dull. It was clear that the two caught today were the first migrants from farther south as they were in very fresh, bright plumage, one white-striped morph and one tan-striped morph. Both birds were aged second-year based on molt limits, and were sexed as male by wing chord (>74mm), so the differences seen below are due to each being a different color morph.

And a common species that we don't catch very often was a single House Finch.

And I'll end with a gratuitous portrait of the same White-throated Sparrow, to show off its bright colors.

Interesting birds observed but not banded included a flyover Common Loon, calling Sora and Virginia Rails, a calling Common Gallinule in the marsh north of the banding area, a briefly heard calling Solitary Sandpiper, two flyover Forster's Terns, three species of warbler; Nashville, Yellow, and the still lingering Louisiana Waterthrush, and a female Rusty Blackbird that gave good views most of the day.

It is also a great relief to have an insect highlight, as insects are finally now becoming active. You know it was a long winter when you're happy to see bugs! This half-inch beetle was found out near the Field Nets, and brought back to the station to be photographed. It is a species that I've seen several times when looking for salamanders. They like to hide under logs so are not often seen. And before now they have been too fast for me to get photos. This one had to be restrained in the ziploc bag that I keep my parking permit in...and an attempt to photograph it outside the bag failed as it flew off almost immediately.
