Mansfield Wrap: Molt, Migration, and a Crowd-Pleasing Owl
VCE’s final 2018 summer banding session on Mt. Mansfield featured a much-anticipated tiny owl, songbirds in heavy flight feather molt, and thoughts about the impending fall migration that will take Bicknell’s Thrush (and VCE biologists) back to Cuba.
Humans and Songbirds Meet Up on Mt. Mansfield
VCE’s 11-12 July field trip to Mt. Mansfield featured favorable weather and plentiful mist net captures. Banding highlights included the season’s first Winter Wren (it’s astounding how tiny these birds are, given the volume of their song!) and Magnolia Warbler, and free-flying juveniles of 3 species. The human element of this trip was especially rewarding, with a 10 year-old and his grandfather, our two summer interns, and several other enthusiastic visitors.
VCE’s 26th Year on Mt. Mansfield Off to a Wet Start
VCE’s 26th consecutive field season on Mt. Mansfield has been so far hampered by wet weather, but neither the birds or our resolve to monitor them have been affected. Our second visit of the young season yielded many mist net captures of birds banded in previous years, underscoring the value of this long-term demographic study.
Weather and Blackpolls Storm Mt. Mansfield
VCE completed its 25th consecutive field season on the Mt. Mansfield ridgeline in dramatic fashion, encountering a storm of both weather and migrant birds. We banded a record 46 Blackpoll Warblers, and Bicknell’s Thrushes were vocalizing actively even as we took down our last nets in the gusty rain.
Owls and Tennessee Warblers Find VCE Nets on Mansfield
VCE enjoyed an eventful, if quiet, final summer field trip to our long-term study site on the Mt. Mansfield ridgeline. Banding highlights included a juvenile Northern Saw-whet Owl, 2 adult Tennessee Warblers, and 12 juvenile Bicknell’s Thrushes.
Seasonal Changes in Evidence on Mt. Mansfield
VCE’s latest field visit to Mt. Mansfield yielded signs that seasonal changes are in store, as free-flying juveniles, molting adults and non-local dispersers are beginning to supplant the resident breeders in our mist nets.
Mt. Mansfield Yields Avian Surprises
VCE’s seventh weekly visit to our long-term study site on the Mt. Mansfield ridgeline yielded a few avian surprises, including the only Indigo Bunting recorded in 25 years of field work.
Mansfield Update: Hardy Survivors and a Site-faithful Sharpie
After forced cancellation of a planned field trip to Mt. Mansfield in early June, when wind chills on the ridgeline plummeted to 14 degrees F, VCE returned on June 15-16. The avian chorus was subdued, but the hardiness of resident birds was evident. A male Sharp-shinned Hawk banded in 2013 was a surprise returnee in our nets.
The Blackpoll Warbler’s Daring Trans-Atlantic Migration
VCE has helped to document one of the most amazing feats of migration on the planet: the Blackpoll Warbler’s flight over the Atlantic Ocean non-stop for up to three days. Our research on the flights is published today in the journal Biology Letters.
