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

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
