Redwing (Turdus iliacus) Science Article 1 abstract A significant proportion of Redwings Turdus iliacus reject non-mimetic model Cuckoo Cuculus canorus eggs experimentally introduced into their nests. However, very few cases of Cuckoo parasitism have been recorded for this species. In the present study we tested the hypothesis that egg rejection by Redwings has evolved as […]

Autumn migration of thrushes over eastern Finland: A comparison of visible migration and ringing recovery patterns
Mistle Thrush (Turdus viscivorus) Science Article 1 abstract The migration of thrushes Turdus spp over eastern Finland was investigated using data from 4,482 foreign recoveries of five species ringed in Finland between 1913 and 2001, and records of visible migration of nearly 28,000 thrushes observed during diurnal autumn movements between 1996 and 2001. Ringing recoveries […]
NOTES ON THE NESTING OF TURDUS LEUCOMELAS IN SURINAM
Pale-breasted Thrush (Turdus leucomelas) Science Article 1 abstract The Grey-headed Thrush (Turdus ZezLcomelas) has a vast range in South America from Colombia eastward to the Guianas and southward to southeastern Brazil, Matto Gross0 and Peru. The representative in Surinam, T. 1. albiuenter, is confined to Colombia, Venezuela and the region from the Guianas southward to […]

AVIAN NESTLING PREDATION BY ENDANGERED MOUNT GRAHAM RED SQUIRREL
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 Nesting in North Carolina
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 […]
DIET AND PREPARATION FOR SPRING MIGRATION INCAPTIVE HERMIT THRUSHES (CATHARUS GUTTATUS)
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, […]
FRUIT ABUNDANCE AND LOCAL DISTRIBUTION OF WINTERING HERMIT THRUSHES (CATHARUS GUTTATUS)AND YELLOW-RUMPED WARBLERS (DENDROICA CORONATA) IN SOUTH CAROLINA
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 […]
Experimental fruit removal does not affect territory structure of wintering Hermit Thrushes
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 […]
A HERMIT THRUSH SONG
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 […]
