Subject: [VTBIRD] New study uses VT eBird data
Thanks everyone for adding your checklists to Vermont eBird, a project of
the Vermont Atlas of Life (https://val.vtecostudies.org/), to help make
studies like this possible!

A new study using sightings reported to eBird found that many migratory
birds time movement to match “green-up” or emergence of leaves, as they
travel north and south. Frank La Sorte, a research associate at the Cornell
Lab of Ornithology and Catherine Graham, a researcher at the Swiss Federal
Research Institute in Switzerland, found that migratory birds that eat
plants and seeds moved north in sync with foliage emergence in the spring.
This is the first study of its kind to examine migration timing in relation
to seasonal changes in greenness for a large number of North American
migratory bird species that feed on a variety of foods including plants,
seeds, nectar, insects, birds, and small mammals. Their findings were
published this week in the Journal of Animal Ecology.
