Nutritional value of winter foods for whooping cranes Nutritional value of winter foods for whooping cranes

We measured metabolizable energy and digestibility of Whooping Crane (Grus americana) winter foods (blue crab [Callinectes sapidus]), common Rangia clam (Rangia cuneata), wolfberry fruit (Lycium carolinianurn [wolfberry]), and live oak acorn (Ouercus virginiana [acorn])] with feeding trials to captive-reared Whooping Cranes. Apparent metabolizable energy coefficients (expressed as %)...

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...

Trouble in paradise: The brown tree snake in the western Pacific Trouble in paradise: The brown tree snake in the western Pacific

The brown treesnake (Boiga irregularis) was recognized as a pest species by Congress in Section 1209 of the Nonindigenous Aquatic Nuisance Prevention and Control Act of 1990 (NANPCA). 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...
