Talk about a crazy day! Today takes the new record for total captures at Captain Sam's for the season! We caught 252 birds total! Despite the continuing rush of common yellowthroats we saw some great variety of warblers among other things today at Captain Sam's. First of season Chestnut-sided warbler, Gray-Cheeked Thrush, Tennessee Warbler, and Eastern Phoebe!

Little Bear
It was an incredibly busy day at Little Bear this morning 167 new birds and 9 recaptures, representing 25 different species. Unfortunately, we were forced to shut down early due to the extremely warm weather. The 176 birds handled this morning were all captured within a less than 4 hours period, producing a record capture rate of 231 birds per 100 net hours. Surprisingly, we did not have any first of the season but we captured 2 more Chestnut-sided Warblers, a Magnolia Warbler, and a handful of Cape May Warblers.
Like most of the warblers, Chestnut-sided Warblers can be
aged by the presences or absences of a molt limit. Hatch-year birds will most often have a molt
limit within their alulas, where A1 is replaced and contrast with the retained A2
and A3. In the example below, you can
see A1 has black center and surrounded by bright green edging and contrast with
the brown and worn A2, A3, and primary coverts.
On after hatch-year birds, the wing will lack any molt limits and all
the coverts will have dark centers and will be relatively fresh.

| After hatch-year Chestnut-sided Warbler |
Chestnut-sided Warblers can be sexed based on the amount of
chestnut they have along their flanks.
After hatch-year males will have the extensive amount of chestnut along
their flanks. After hatch-year females
can have a few hints of chestnut or can completely lack it. Hatch-year birds with chestnut along their
flanks can be sexed as males but birds without chestnut are better left as
unknown because both males and females can completely lack chestnut.
