Leg bands are commonly used to mark shorebird chicks as young as 1-d old, but little is known about the possible impacts of bands on survival of prefledging shorebirds. We used a mark-recapture framework to assess the impact of bands and banding[...]

Censusing seabirds from coastal areas requires reliable estimates of bird numbers and the distances of the birds from the coastline. Logistical constraints make visual estimation of distances the only feasible method in many studies. We tested t[...]

The potential advantages of repeated breeding at a particular location should improve reproductive performance in long-lived species of birds. However, for short-lived species, natural selection should favor individuals that most quickly develop[...]

Individual markers are essential for measuring survival rates, but few reliable techniques exist for marking young waterfowl. We banded 572-d-old Mallard (Anas platyrhynchos) ducklings from 85 broods with plasticine-filled leg bands in 2006-2007[...]

To ensure adequate protection of nonbreeding habitats used by Neotropical migratory landbirds, we must first address questions about habitat use and quality. On the Yucatan peninsula, migrants use many habitats, several of which remain unstudied[...]

Population size and trends are demographic parameters that can be used to help determine the threat of extirpation or extinction of bird populations and in determining management strategies. Chapada Flycatchers (Suiriri islerorum) are endemic to[...]
