Hermit Thrush (Catharus guttatus) Science Article 2 abstract Studies using artificial nests or remote cameras have documented avian predation by redsquirrels (Tamiasciurus hudsonicus). Although several direct observations of avian predation events are known in the northern range of the red squirrel distribution, no accounts have been reported in the southern portion. We observed predation upon […]

Hermit Thrush (Catharus guttatus) Science Article 4 abstract The Hermit Thrush (Catharus guttatus) is a widespread breeder innorthern forests in Canada and the United States. In the eastern U.S. thisspecies is found breeding from northeastern Minnesota east through NewEngland and New York and south to extreme northeastern New Jersey andnorthern Pennsylvania, with isolated populations in […]

Hermit Thrush (Catharus guttatus) Science Article 1 abstract We conducted winter censuses of two short-distance migrants, Hermit Thrushes(Catharus gu
atus) and Yellow-rumped Warblers (Dendroica coronata), over seven years in fi ve diff erent habitats to determine whether their local abundances could be predicted by fruit pulp biomass. Sampled habitats were stands of upland and bottomland […]

Hermit Thrush (Catharus guttatus) Science Article 3 abstract 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 absence of preferred arthropod resources, are a primary food resource for wintering Hermit Thrushes […]

Hermit Thrush (Catharus guttatus) Science Article 5 abstract During the summer of 1902 I stayed from the twenty-fourth of June to the thirtieth of July at a camp on the shore of Lake Memphremagog. My tent was placed at the edge of a cedar andhemlock grove, mixed with occasional maples and birches which furnished nesting […]

Hermit Thrush (Catharus guttatus) Science Article 7 abstract Despite the Hermit Thrush’s wide distribution and exceptional singing ability, its vocal behavior is poorly known. In recorded samples from Arizona and New England, weshow that males have repertoires of 6 to 12 discrete song types. Those types can be presented in highly regular sequences, but the […]

Hermit Thrush (Catharus guttatus) Science Article 6 abstract Seasonal changes in food choice by migratory birds often reflect changes in relative food abundance and increased energetic demand. Hermit Thrushes (Catharus guttatus) in southeastern Louisiana are highly frugivorous during winter but forage exclusively onarthropods just prior to spring migration. JENNIFER A. LONG AND PHILIP C. STOUFFER, […]
