Dispersal and habitat use by post-fledging juvenile snowy egrets and black-crowned night-herons Dispersal and habitat use by post-fledging juvenile snowy egrets and black-crowned night-herons

We studied the postfledging dispersal movements and habitat use of juvenile Snowy Egrets (Egretta thula) (SNEG) and Black-crowned Night-Herons (Nycticorax nycticorax) (BCNH) in coastal Virginia using a dye (picric acid) and radiotelemetry. Results from monitoring radiomarked birds revealed significant differences both years between species, with SNEGs dispersing more widely than BCNHs...

Age-specific survival and philopatry in three species of European ducks: A long-term study Age-specific survival and philopatry in three species of European ducks: A long-term study

Capture-recapture and band recovery models were used to estimate age-specific survival probabilities for female Northern Shovelers (Anas clypeata), Common Pochards (Aythya ferina), and Tufted Ducks (Aythya.fuligula) at Engure Marsh, Latvia, in 1964-1993. We banded more than 65,100 day-old ducklings of both sexes and captured 10,211 incubating females (3,713 new bandings and 6,498...

Like aquatic pests, tree snakes are sometimes dispersed by ships, have wide-ranging effects on natural and human communities, and threaten to spread to other areas. The problems they are causing on Guam, a...
