Geographic variation of the Veery

Veery (Catharus fuscescens) Science Article 3 abstract the course of identifying Ohio Veeries the writer recently discovered further evidence supporting the suspicions of Howe (Auk, 17: 20, 1900) and Bangs (Bull. Mus. Comp. Zool., 70: 331, 1930) that the form described by Ridgway from Fort Garland, Colorado, as Hylocichla fuscescen salicicola, commonly called the Willow […]

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 […]

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 […]

JUVENILE AND ADULT SURVIVAL OF SWAINSON’S THRUSH (CATHARUS USTULATUS) IN COASTAL CALIFORNIA: ANNUAL ESTIMATES USING CAPTURE-RECAPTURE ANALYSES

Swainsons Thrush (Catharus ustulatus) Science Article 1 abstract We estimated annual rates of survival for juvenile and adult Swainson’s Thrushes (Catharus ustulatus) using capture-recapture analyses from 22 years of mist-netting data in coastal California (n = 2,651 individual captures). Our apparent survival estimate was 56% for adults and 25% for juveniles. We are the first […]

Documented Winter Records of Swainson’s Thrush in U.S.A. and Canada

Swainsons Thrush (Catharus ustulatus) Science Article 4 abstract Part of the documentation for an ‘out-of-season’ bird may be its being banded by a reputable bander. Since banding data often contribute to patterns of change in bird distribution, it might be advantageous to leave unverified records in the Bird Banding Laboratory’s database with a code indicating […]

Hurricane-Related Vagrancy of Swainson’s Thrush and Veery in Puerto Rico

Swainsons Thrush (Catharus ustulatus) Science Article 5 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 […]

THE IMPORTANCE OF FRUIT TO SWAINSON’S THRUSHES, CATHARUS USTULATUS, DURING FALL MIGRATION: A FIELD TEST OF PLASMA METABOLITE ANALYSIS

Swainsons Thrush (Catharus ustulatus) Science Article 2 abstract I evaluated the hypothesis that fruit availability significantly influences stopoverhabitat quality for fall migrating Swainson’s Thrushes (Catharus ustulatus) in coastalnorthern California. I analyzed plasma metabolites (triglycerides,
