Mansfield Update: The Kids Are Coming
Week 6 of VCE’s 2019 banding season on Mansfield brought a second consecutive bump in mist net captures, and the first appearance of locally-hatched juveniles. Human youngsters also highlighted the week.
Mansfield Birds Rebound Modestly in Week 5
Mist net captures on Mt. Mansfield rebounded modestly during week 5 of VCE’s 2019 banding season. While encouraging, overall numbers are still abnormally low. A scarcity of yearling birds suggests that recruitment has been low, possibly resulting from a poor 2018 breeding season.
Mansfield One-month Update—Where Are All the Birds??
One month in to VCE’s 28th field season on Mt. Mansfield, bird populations are as low as they’ve ever been. We’ve netted only 43% of the numbers we had at this date a year ago. What is going on??
Avian Surprises on the Mt. Mansfield Ridgeline
VCE’s third visit of 2019 to the Mt. Mansfield ridgeline brought fine weather and some unusual avian encounters, including our first-ever mist net capture of a Mourning Warbler. Overall, activity continues to be low, with numbers of captures <50% of what they were a year ago, but it's far too early to push the proverbial panic button and declare "silent spring"!
VCE’s 28th Mansfield Season Begins on a Quiet, Chilly Note
VCE’s 28th field season studying the breeding birds on Mt. Mansfield ridgeline is off to a quiet and chilly start. Vocal activity has been subdued and mist net captures low, but inevitable avian surprises have kept banders’ spirits high.
From New England to Colombia, Migratory Species Rely on Grassland Ambassadors – Part III
VCE biologist Rosalind Renfrew spent three weeks in Colombia with conservation partners Asociación Calidris for migratory grassland bird research and outreach. Read this final post of a three-part series about this incredible shared learning experience.
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.
