We banded a nestling Bicknell's Thrush (Catharus bicknelli) in southern Vermont and recaptured the same individual 19 months later on its wintering territory in the Dominican Republic. Such recaptures, where both the natal or breeding site and w[...]

Forest fragmentation can create negative edge effects that reduce the reproductive success of birds nesting near the forest/nonforest interface, and threaten bird populations deeper in remnant forest habitats. Negative edge effects may be more p[...]

The threatened Atlantic Coast population Of Piping Plovers (Charadrius melodus) has not increased in recent years and remains 332 pairs short of the recovery goal of 2000 pairs. Habitat loss to development is a major threat to the population, an[...]

Food is generally considered to be the primary resource structuring winter territories in migrant songbirds, but there is little experimental evidence to support this. In southeastern Louisiana, ripe fruits, consumed opportunistically in the abs[...]

Many temperate-zone birds must track seasonal variation in food availability to time breeding and enhance reproductive success. However, the external cues birds use to fine-tune sexual development and timing of reproduction remain unclear. One p[...]

Adult Common Terns (Sterna hirundo) reportedly respond to nocturnal predation by deserting colonies from the time of disturbance until dawn the following morning. However, direct evidence for this behavioral response is limited because the noctu[...]

Shorebirds migrating through the Southern Great Plains (SGP), USA, use freshwater playas and saline lakes as stopovers. The importance of playas is well documented, but the role of saline lakes is not clearly understood. During 2002 and 2003, we[...]

We tested the hypothesis that the abundance of Brown-headed Cowbirds (Molothrus ater) and their hosts, as well as parasitism rates, changed between 1992-1993 and 2001-2003 in riparian habitats in the Okanagan Valley, British Columbia, Canada, wh[...]

Accurate determination of nest fates and nest predators is possible through continuous video monitoring, but such monitoring is relatively expensive and labor intensive. If documenting of the timing of nest termination events is Sufficient, then[...]

Although sexual differences in birds can be extreme, differences between males and females in body size and plumage color are more subtle in many species. We used a genetic-based approach to determine the sex of male and female Steere's Liocichl[...]

The Mouth of the Yangtze River is an important stopover site for migratory shorebirds using the East Asian-Australasian Flyway. From 1984 to 2004, we censused and banded shorebirds and monitored hunting activities at the mouth of the Yangtze Riv[...]

In studies of avian nest success, investigators often face the difficult task of periodically checking nest status while at the same time limiting observer influence on nest survival. Remotely monitoring nests using temperature data loggers is o[...]

Carotenoid-based coloration of skin and plumage has been found to be correlated with individual quality in many species of birds during the breeding season. However, less is known about the possible role of these signals during the nonbreeding s[...]

Territorial songbirds generally use song to defend territories and attract mates, but conspecific song may also serve as a cue to attract other male songbirds to a breeding site. Although known to occur in some colonial and forest-associated spe[...]
