Thank you for this report, Chris, and thank you so much for welcoming us to witness that wonderful work you, Brendan, and the rest of your staff does up on that beautiful mountain. To say we appreciated it would be an understatement.

Continued good luck with your/our birds.
Barbara Brosnan

Subject: [VTBIRD] Mansfield week 4

This week's Mansfield session marked VCE's fourth visit to the mountain in
2018. A crew of visitors, including a lively group from Otter Creek
Audubon, were treated to a solid assortment of mist-netted birds, though
fewer surprises than last week. Weather was cool and dry. The avian nesting
season is clearly in full swing, as females of all species showed
well-developed incubation/brood patches. Small groups of siskins are still
present on the ridgeline, though crossbill numbers seem reduced -- we
caught juveniles of both species. I did finally hear a distant Winter Wren
sing, but their abundance is distinctly low, as is that of Swainson's
Thrush (back to numbers of 10-20 years ago). We had our first red squirrel
sightings of the season, with two individuals. This year's cone crop is
non-existent -- I have yet to see a single fir or spruce cone.

Included among the 57 birds we captured on Tues-Wed:

Least Flycatcher 1 female with regressing brood patch
Red-breasted Nuthatch 1 male
Bicknell's Thrush 12 2 new yearling males, 10 within-season retraps
Swainson's Thrush 2 2 within-season retraps
American Robin 4 2 new, 2 within-season retrap
Blackpoll Warbler 11 4 new (3 males), 2 returns (male from 2016,
female from 2017), 5 within-season retraps
Black-throated Blue Warbler 1 female
Yellow-rumped Warbler (Myrtle) 4 males: 1 new; 1 return from 2017, 2
retraps
Dark-eyed Junco (Slate-colored) 3 1 new female, 1 return male banded
as hatch-year on 2 Aug 17, 1 retrap
White-throated Sparrow 13 9 new (8 males, 1 female), 4 within-season
retraps
Purple Finch 1 new yearling male; we've now banded 8 this year vs. 1
in all of 2017
White-winged Crossbill 1 free-flying juvenile, flight feathers >85-90%
full-grown; likely a locally-hatched bird
Pine Siskin 2 free-flying juveniles
