Site Fidelity and Natal Philopatry in Dickcissels
Spiza americana (Dickcissel) colonized a restored Conservation Reserve Program grassland in Maryland during the second year of restoration and has continued to return in subsequent years. In 2000–2010, we banded 125 adult and hatch-year birds; during this period the population ranged annually from one to 16 individuals. Twenty-one percent of adult male Dickcissels (n = 38) returned in a subsequ...
متن کاملHippocampal Astrocytes in Migrating and Wintering Semipalmated Sandpiper Calidris pusilla
Seasonal migratory birds return to the same breeding and wintering grounds year after year, and migratory long-distance shorebirds are good examples of this. These tasks require learning and long-term spatial memory abilities that are integrated into a navigational system for repeatedly locating breeding, wintering, and stopover sites. Previous investigations focused on the neurobiological basi...
متن کاملNatal Philopatry and Apparent Survival of Juvenile Semipalmated Plovers
—Natal philopatry is rare in long-distance migrant shorebirds and requires long-term population studies to detect. We report on the rate of natal philopatry from a 18-year study of Semipalmated Plovers (Charadrius semipalmatus) marked as hatchlings to an arctic breeding site near Churchill, Manitoba. About 2% (27/1271) of banded hatchlings returned to the Churchill area to breed. There was no m...
متن کاملPerformance-enhancing role of dietary fatty acids in a long-distance migrant shorebird: the semipalmated sandpiper.
At the end of summer, semipalmated sandpipers (Calidris pusilla) traveling from the Arctic stop in the Bay of Fundy (east coast of Canada) to build large fat reserves before a non-stop flight to South America. During a 2-week stopover, the body mass of this small shorebird is doubled ( approximately 20 g to 40 g) by feeding on a burrowing amphipod, Corophium volutator, that contains unusually h...
متن کاملAtypical Nest Site of a Semipalmated Plover
—We report on an unusual nest site of a Semipalmated Plover (Charadrius semipalmatus) at La Pérouse Bay, Manitoba, Canada. The nest was located at the base of a 41-cm-high willow (Salix spp.) in a dense willow patch surrounded by coastal mudflats. Vegetation height and percent visual obstruction at the nest site were unusually high compared to height and cover previously described for Semipalma...
