White-tailed Kite (Elanus leucurus) Science Article 1 abstract I examined the diet of breeding White-tailed Kites (Elanus leucurus; Aves; Accipitridae) and Barn Owls (Tyto alba; Aves; Tytonidae) in an agrarian area of southern Brazil by analyzing regurgitated prey remains. The objective was to evaluate how these raptors, which differ markedly in their hunting activity periods […]

PREY OF THE WHITE-TAILED KITE IN CENTRAL CHILE AND ITS RELATION TO THE HUNTING HABITAT
White-tailed Kite (Elanus leucurus) Science Article 3 abstract Between November 1973 and January 1974 we collected 702 pellets of Whitetailed Kites (Elanus lecurus) in two areas of central Chile differing in their vegetation physiognomy (disturbed versus undisturbed). We compared the diversity, age structure, and mean prey size of items found in pelletsf rom both simmTs.h […]
Natal and breeding dispersal in the mount White-crowned Sparrow Zonotrichia leucophrys oriantha.
White-crowned Sparrow (Zonotrichia leucophrys) Science Article 1 abstract Dispersal data were collected on Mountain White-crowned Sparrow Zonotrichia leucophrys oriantha, an open-nesting migratory songbird breeding in high elevation meadows of the Sierra Nevada of California. Young birds began to move soon after fledging. Although some remained on their meadow of birth until migration, most moved away. […]

Hurricane-Related Vagrancy of Swainson’s Thrush and Veery in Puerto Rico
Veery (Catharus fuscescens) Science Article 4 abstract Low pressure waves that contributed to the formation of Hurricane Wilma in the westernCaribbean produced westerly winds in the central Caribbean and Puerto Rico during the second week of October, 2005. On October 12 and for the following two weeks Swainson’s Thrush (Catharus ustulatus, six locations) and Veery […]
Spatial heterogeneity in predator activity, nest survivorship,and nest-site selection in two forest thrushes
Veery (Catharus fuscescens) Science Article 6 abstract The ability of prey to find and use predator-free space has far-reaching consequences for their persistence and interactions with their predators. We tested whether nest survivorship of the ground-nesting veery (Catharus fuscescens) and shrub-nesting wood thrush (Hylocichla mustelina) was related to the local absence of a major nest […]
First photographic evidence of Veery (Catharus fuscescens) for Peru
Veery (Catharus fuscescens) Science Article 1 abstract The Veery (Catharus fuscescens) is little known in Peru. We present the first photographic evidence of Veery in Peru during October 2004. The date of our observation and of other sight-records suggests that Veery is a rare migrant in extreme eastern Peru. Michael J. Andersen et al, Boletin […]
TRUE WINTER RANGE OF THE VEERY (CATHARUS FUSCESCENS): LESSONS FOR DETERMINING WINTER RANGES OF SPECIES THAT WINTER IN THE TROPICS
Veery (Catharus fuscescens) Science Article 2 abstract Most recent references describe the winter range of the Veery (Catharus fuscescens) as including an extensive area from northern Colombia, Venezuela, and Guyana south to south-central Brazil. Analysis of seasonal distribution of specimen records in SouthAmerica, however, shows that 91 of 105 specimens were taken during spring and […]
Removal of Banded Cowbird Nestling by Veery
Veery (Catharus fuscescens) Science Article 5 abstract In the course of a nesting study of the Veery (Hylocichla fuscescens) made at the University of Michigan Biological Station, at Douglas Lake, Cheboygan County, Michigan, in July, 1956, I banded a young Brown-headed Cowbird (Molothrus ater). At that time, the nest contained two Cowbirds, which had hatched […]
