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??
VCE and Colleagues Quantify Effects of Hurricanes Irma and Maria on Puerto Rico’s Forest Birds
In September of 2017, hurricanes Irma and Maria delivered a devastating one-two punch to Puerto Rico, causing massive defoliation of the island’s forests. While the detrimental effects of these storms on human populations were well-documented, little was known about how the island’s bird populations were affected—until now.
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.
VCE Paper Confirms Scarcity of Bicknell’s Thrush on Puerto Rico
A recent peer-reviewed paper by VCE confirms that Bicknell’s Thrush is a rare and local but regular winter resident in mid-high elevation forest of Puerto Rico. VCE’s findings also highlight the strategic importance of continuing to focus habitat conservation efforts on Hispaniola, which supports the lion’s share of this globally vulnerable species in winter.
VCE Breaks New Ground (Literally) in Cuba
VCE’s 2019 field expedition to Cuba’s remote Bayamesa mountain range pioneered new ground, endured a few hardships, uncovered small numbers of overwintering Bicknell’s Thrush, and yielded comparisons with legendary Swedish botanical explorer Erik Ekman a century earlier.
From Snowbanks to Cloud Forests: Chris Rimmer is Cuba Bound
VCE’s Chris Rimmer is bound for eastern Cuba. He’ll trade a foot-plus of new snow and subzero temperatures for humid cloud forests and Cuban Trogons.
In Haiti, Mass Extinction Underway as Deforestation Nearly Complete
A recent study reveals an unprecedented biodiversity crisis in Haiti. At current rates of deforestation in this overpopulated country, all of its original primary forests—and the majority of species that inhabit them—will vanish within 20 years.
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.
Mansfield Update: Hatch-years Predominate
VCE’s penultimate summer banding session featured relatively few birds, some very warm and humid weather, a preponderance of youthful banders, and several family members.
Mansfield Update: the Ridgeline Quiets, Planets Shine
VCE’s mid-July banding session on Mt. Mansfield featured diminished bird song, but a surprise Tennessee Warbler and spectacular planetary viewing.
