Highlights of the 23 birds banded on Thursday, May 23 included a female Ruby-throated Hummingbird that was already banded. Checking the records, it was banded in fall 2010 as a hatch-year female, so it is 2 years 11 months old.

One of the most surprising season firsts today was a single Swainson's Thrush. It is surprising because normally the first one is captured here before May 10, and they typically peak in numbers around May 20.

Among the few migrant warblers captured today were two Magnolia Warblers, a single Ovenbird, and this second-year male American Redstart. How many birders would call this a female in the field because of the yellow on the wings and tail, overlooking the black blotches on the head?

Interesting birds observed but not banded today included a pair of Spotted Sandpipers observed copulating, a calling Yellow-billed Cuckoo, a singing Willow Flycatcher, a rather late but clearly seen Hermit Thrush, and Tennessee, Black-throated Blue, Bay-breasted, and Wilson's Warbler, and Northern Waterthrush.
Highlights of the 46 birds banded on Friday, May 24 included a first ever for the station, and a first for me personally as well, a Spotted Sandpiper! This individual was aged after second-year because it showed no pale fringing on any feathers on the upperparts, and sexed as female because of the numerous large spots on the underparts (males have fewer and smaller spots according to Pyle).

The first "Traill's" Flycatchers of the season were represented by five individuals banded today, two of which keyed out as Alder Flycatcher.

For the second time, Eastern Phoebe makes the list of highlights because of how late one was banded. Back on May 4 an individual was record late for this site by 16 days. So, today's bird, more than a month past the previous record, was extraordinary since they do not nest in the park as far as I know, so are only migrants here.

It was also a good day for banding swallows, with two Barn Swallows and two Northern Rough-winged Swallows.

The Barn Swallows were both sexed as female based on the relatively short tail fork measurement, and one individual also had an extensive brood patch.

There was one male and one female Northern Rough-winged Swallow; the male sexed based on the rough little hooklets along the leading edge of the 10th primary. The female was a bit unusual in that she seemed to have some oily patches on her head and wings, probably from building a nest in some dirty pipe in the area.

Interesting birds observed but not banded included a calling Virginia Rail, single Magnolia Warbler, Bay-breasted Warbler, and American Redstart.
Highlights of the 30 birds banded on Monday, May 27 included the third Ruby-throated Hummingbird of the spring (plus one returnee on Thursday), plus two more fledgling Carolina Wrens. These were almost certainly two more from the brood from which two were banded more than a week ago, as they were captured in the same general area.
Hatch-year Carolina Wren |
And returning to the highlights again is the Veery, one of which was captured today bringing the season's total to a record of 10. Although single Swainson's and Gray-cheeked Thrushes were also captured today, only the Veery has been banded in good numbers, with these other two species notably scarce so far.

Interesting birds observed but not banded included a winnowing Wilson's Snipe, which has not been heard in more than two weeks, and singing Alder and Willow Flycatchers, and singing Magnolia, Bay-breasted, and Wilson's Warbler, and American Redstarts.
