ESKIMO CURLEW RESEARCH NOW AVAILABLE

Plumage states of the Eskimo Curlew
Our Eskimo Curlew research is now available as an open access document at http://www.birdconservationresearch.org/…/eskimo%20curlew%2…
It investigates the external anatomy of males vs. females and adults vs. juveniles, and identifies two previously undescribed plumage states. One of these states (see photo) exhibits prominent y-shaped markings on the breast whereas the other exhibits linear markings. It also documents, based on specimen data, the species' historical distribution.

YALE FOREST BIRDS SHOW POPULATION INCREASE


Bird populations at Yale Forest have increased since 1985, but the amount of variability among individual study sites has also increased. As the figure shows, surveys were duplicated each year to gain a perspective of survey variability.

Unlike continental trends, which show that birds have declined by 30%, forest birds in northeastern Connecticut have undergone a 20% increase. Read about this and more in Bird Conservation Research's October newsletter: http://www.birdconservationresearch.org/pdf/bcr%20newsletter%2021-4.pdf.
