We Roll With the Blackpoll!

 Captain Sams:

Our day started later than expected this morning due to the presence of a rain cloud seemingly stuck over the banding station. After it parted, we set out under cloudy skies and blowing winds to open the station, and we finished doing so a little after 9:00 a.m. In the 4 hours that followed, we captured 44 total birds; 35 new and 9 recaptures. 

With great surprise, amongst our seemingly endless Common Yellowthroats, was the station's first Blackpoll Warbler of the year! Our individual was an after-hatch-year female, and she gave us good looks at the dramatic change in appearance these birds go through between their basic and alternate plumages!

In the Spring, these warblers sport an achromatic alternate (breeding) plumage, made up of blacks and whites. They also have an incredibly high-pitched call that birders akin to that of a tiny helicopter passing by, how specific! During Fall, individuals show off a completely different, and quite cryptic, basic (non-breeding) plumage made up of greens, greys, and blacks. In fact, so similar is Blackpoll Warbler plumage in Fall to that of another warbler, the Bay-breasted Warbler, that birders must rely on the soles of their feet to distinguish them. The former has soles that are yellow; the latter has soles that are blue-gray.

We were also excited to catch another adult warbler, an after-hatch-year female Northern Parula. Breeding males of this species show off a flashy color pattern of yellow, blue, and brown on their throats, but our lady was quite a stunner too! From the bright lemon-yellow of her throat to the rich olive-green on her back, she was all color and all spunk, giving us a great end to our day at the station!

With Northeastern winds to continue over the coming days, we expect more exciting migrants and a whole ton more birds. Hopefully, these predictions come true!

Little Bear:

Todays weather was a little off and we started out our morning a little later than normal. With the unpredictable rain and wind, we ended up closing up still a little early. We ended our morning with a total of 37 birds with only 3 of them recaptured. We had a special recapture today with a Carolina Chickadee that was banded from previous years. Usually at LB we don't catch as many recaptures from previous years, so I do enjoy seeing these cuties. This one was banded in 2021 in August as a hatch year bird. I love seeing recaptures coming back and seeing how well they are doing since we banded them!
