Re: [nysbirds-l] Barn Swallow question
Further to Bob Paxton's comment about Tree Swallows' love affair with feather lining of their nests, I have found these birds very resourceful with their feather gathering depending on the nature of their local habitat. For years I have monitored nest boxes in Upstate counties of Schenectady, Saratoga, Schoharie and Montgomery. Depending on location, these swallows gather feathers of a wide range of species, as well as in varying quantity. Rural areas are more endowed with local fowl than are suburban areas leading to easier gathering. For instance the nest boxes at the Landis Arboretum in rural Schoharie Co. with roosters crowing in the distance had much larger gatherings of goose, duck and chicken feathers in general than did the boxes at West Hill, a suburban residential area in the Town of Rotterdam in Sch'dy Co where Great Horned Owl feathers made an almost annual appearance. In some areas the tan body feathers of barnyard geese are very popular, but so can be white feathers from domestic ducks. Less numerous are flank feathers from male Mallard, Wood Duck and body feathers of Wild Turkey. Some of the rarer choices are from Great Blue Heron, Great Horned Owl (body), No. Saw-whet Owl (primaries) and the strangest of all: Common Nighthawk. One nest in Montgomery Co contained 5-6 nighthawk feathers including flight feathers (rectrix and wing) suggesting that this swallow had found a dead nighthawk and was harvesting feathers from it. Nighthawks molt away from the northeastern U.S. spring nesting season. Feathers, flight and body, from local passerines also show up in these nests on rare occasion. But far and away, body feathers of barnyard fowl are the most common Tree Swallow nest lining material in these counties.

[nysbirds-l] ADK Chickadee Irruption Winding Down
This past winter the 7th major Black-c. Chickadee irruption in the past 50+ years of banding occurred at my Adirondack camp at Jenny Lake near Corinth in northern Saratoga Co. at an elevation of 1250 ft. The irruption started slowly in Nov, appeared to falter in Dec, then kicked into high gear in mid-Jan as follows.Date BCCH Banded/Total BCCH Captures Including Previous Bandings12/21/20 3/71/1/21 9/41/12/21 37/401/19/21 41/602/4/21 46/642/11/21 29/732/18/21 17/532/26/21 26/703/7/21 20/573/13/21 10/373/23/21 4/12These captures were made using 3 mist nets, one at each of three sunflower seed feeders over a span of 2.5-3.5 hrs.Here's how these results rank compared to six past major irruptions.Year No. Banded/Returns From Prev. Yrs Total Captures80-81 320/68 38881/82 153/108 26190/91 268/71 33999/00 165/95 26008/09 281/66 34714/15 285/64 34920/21 238/25 263The years referred to here begin Jul 1 (the month newly fledged young appear) running to Jun 30 of the following year.Two aspects of this year's irruption make it unique from others in the past. Its timing was different. Most irruptions begin in Oct/Nov, peak in Dec/Jan usually declining thereafter as birds return to breeding areas. This irruption was barely in progress in Dec/early Jan, began ramping up in mid-Jan, peaked in Feb into early Mar, declining thereafter. Sunflower seed consumption had a similar pattern. It averaged 100-200 g/day in Nov/Dec, skyrocketed upward in Jan to a peak of 1850 g/day (4 lbs/day) by 2/4/21. It ran 1300-1850 g/day from mid-Jan to mid-Mar when a total of 114.5 kg (252 lbs) was consumed.Secondly, its age composition was different. It consisted mostly of immature birds hatched in 2020 and relatively very few adult returns. In the summary of the seven largest irruptions noted above, the 25 returns noted this year is far below the range of 64-108 for the other six years. Among the 238 birds banded so far this year, 87% were immatures and 13% adults. For the total sample of all 263 captures, that ratio is 80% immature/20% adult.There was also a Red-br Nuthatch irruption most of which passed by Jenny Lake going south, only to increase in Mar as birds began returning north. Bandings were as follows.Jul-Dec 17Jan-mid-Feb 5Late-Feb 8Mar 24 with a max of 12 on 3/7/21, total so far: 54.A Tufted Titmouse irruption of sorts began in mid-Nov with 5 banded in Nov, 2 in Dec, 5 in Jan, 3 in Feb and 2 in Mar for a total of 17.

Re: [nysbirds-l] White Red-tails
Rich - as a winter raptor bander in eastern Upstate NY for the past 23 years, I have banded three leucistic Red-tails as follows. 1) On 3/18/03 an after-third-year probable female in the Town of Florida, Montgomery Co. 2) On 2/18/17 an after-four-year probable female in the Town of Glen, Montgomery Co. That winter, residents of the area where this bird was banded claimed that two leucistic birds existed. 3) On 1/15/19 a second-year bird in the Town of Ft. Edward, Washington Co. This bird had been reported repeatedly by birders in the area from summer through fall, 2018 into the winter of 2018-2019.Amazingly, this bird was recaptured 1/27/20 in the Town of Halfmoon, Saratoga Co., 23 mi to the S of where banded. An account with photos will appear shortly in No. Am. Bird Bander. Every feather on this bird was white earning it the name "Snow White." The prior two birds were predominantly white with some few normal brown or orange flight feathers and scattered brown in their body plumage.

[nysbirds-l] Rufous Hummer banded in Baldwinsville, NY
Yesterday, 12/3/20, an imm./F Rufous was banded at a private residence in Baldwinsville, Onondaga Co, NY (just NW of Syracuse), air temp 37*F., 1" previous day's snow on the ground, warmed to 41*F. Species/age/sex determined by measurements and plumage. The bird was healthy weighing 3.82g, fat class 1 on a 0-3 scale. While being processed, the hand-held bird was allowed to feed from a feeder. Interestingly, after weighing at 3.82g, it was allowed a feeding session during which time it drank eagerly, and was reweighed: 3.98g, a 0.18g or 4.2% weight gain. The bird visits several neighborhood feeders and was back feeding after release. A detailed report on data collected will be filed with NYSARC.

Front 8 mm of forehead plumage renewed, contrasting with wear and color of retained juvenile head/body; occasional sheaths on body. Age confirmed by striations on maxilla, sex by measurements and shape of R2. Various measurements ruled out other Selasphorous species possibilities.

!important;border-radius: 2px;}Larry - as you correctly point out,
brown-plumaged Purple Finches can be females or imm. males. A brown bird is
not automatically a female even though field guides give that impression. The
imm. males don't acquire rosy adult male plumage until their molt in Jul-Sep of
the year after they hatched.
Certain species of passerines show sexual variation in the extent of their
migration; males remaining farther north than females to be closer to their
breeding area come spring to claim their territories. I'm not certain if
Purple Finches do this, but from year-round banding work that I've done at at
my Adirondack camp at Jenny Lake near Corinth in Saratoga Co, adult male
finches outnumber and outlive females.
In a 47-yr study conducted 1970-2016 at JL I banded 13,256 Purple Finches
primarily during the breeding season and recaptured 3,240 of them in subsequent
years. Imm. brown birds were 6,017 of the total 13,256. Among birds banded
as adults, males outnumbered females 51.9% to 48.1%; and among the 3,240 return
recaptures of those adult birds, males outnumbered females 61.5% to 38.5%.
Among the 6,017 banded brown imm., which were later recaptured as adults when
their sex could be determined, males outnumbered females 58.9% to 41.1%.
The oldest recaptures by sex were two males at 11yr-01mo and a female at
10yr-0mo. Repeatedly, year after year, return captures 5 yrs old or more were
predominantly male, 65.7% male to 34.3% female. The No. Am. age record is a
male at 12yr-08mo in NC.
I banded another 3007 Purple Finches in my yard in Schenectady, 1964-2008,
primarily as winter visitors. The three largest invasions were 303 banded in
1965, 808 in 1975 and 1323 in 1977. Apr was the month of greatest abundance as
migrants poured north: 1260 banded out of the 3007 total banded.
Sadly, Purple Finches no longer appear in my yard, and they have declined 52%
as breeders at Jenny Lake (elev. 1236 ft.) as a result of climate change, the
local Adirondack forest no longer cool enough to their liking.
Enjoy your visitors,
