SIMONS 2 CooperativeFish and Wildlife Research Unit, Department of Zoology,North Carolina State University, Raleigh, North Carolina 27695, USA ABSTRACT.--Recentevidence suggests that the nestingsuccess of forest-interiorNeotrop- ical migrantsis lower in fragmentedhabitat. We examinedthe nestingsuccess of Wood Thrushes(Hylocichla mustelina) in a largecontiguous forest from 1993 to 1997.From a sample of 416nests we testedfor predictorsof daily nestsurvival rates, including activity at the nest andvegetation parameters at the nestsite. We tested whether disturbance during nest checks (asmeasured by the behaviorof the adults)was relatedto subsequentnest predation. Fe- maleswere more likely to vocalizewhen brooding chicks than when incubating eggs. How- ever,we found no evidencethat observerdisturbance or WoodThrush activity influenced daily nestsurvival rates. Wood Thrushes nested predominately in smallhemlocks, generally surroundedby many other small hemlocks.However, survival ratesof nestsin hemlocks were not significantlydifferent from thosein othersubstrates. Overall, neither activity at the nestnor habitatin the vicinityof the nestwas a goodpredictor of nestingsuccess, and only onevegetation characteristic, a measure of concealment,was significantly correlated with successfulnesting. Brood parasitism by Brown-headedCowbirds (Molothrus ater) was extremelylow (<2% of nestsparasitized). However, nesting success was moderate(daily survivalrate = 0.958)when comparedwith otherpublished studies from more-fragmented landscapes.Our resultssuggest that daily nestsurvival rates do not increasemonotonically from smallto very largeforest patches.

  • Pattern and Chronology of Prebasic Molt for the Wood Thrush and Its Relation to Reproduction and Migration Departure
    Wilson Bull., 110(3), 1998, pp. 384-392 PATTERN AND CHRONOLOGY OF PREBASIC MOLT FOR THE WOOD THRUSH AND ITS RELATION TO REPRODUCTION AND MIGRATION DEPARTURE J. H. VEGA RIVERA,1,3 W. J. MCSHEA,* J. H. RAPPOLE, AND C. A. HAAS ’ ABSTRACT-Documentation of the schedule and pattern of molt and their relation to reproduction and migration departure are important, but often neglected, areas of knowledge. We radio-tagged Wood Thrushes (Hylocichlu mustelina), and monitored their movements and behavior on the U.S. Marine Corps Base, Quantico, Virginia (38” 40 ’ N, 77” 30 ’ W) from May-Oct. of 1993-1995. The molt period in adults extended from late July to early October. Molt of flight feathers lasted an average of 38 days (n = 17 birds) and there was no significant difference in duration between sexes. In 21 observed and captured individuals, all the rectrices were lost simultaneously or nearly so, and some individuals dropped several primaries over a few days. Extensive molt in Wood Thrushes apparently impaired flight efficiency, and birds at this stage were remarkably cautious and difficult to capture and observe. All breeding individuals were observed molting l-4 days after fledgling independence or last-clutch predation, except for one pair that began molt while still caring for fledglings. Our data indicate that energetics or flight efficiency constraints may dictate a separation of molt and migration. We did not observe Wood Thrushes leaving the Marine Base before completion of flight-feather molt. Departure of individuals with molt in body and head, however, was common. We caution against interpreting the lack of observations or captures of molting individuals on breeding sites as evidence that birds actually have left the area.

The chimney swift's genus name, Chaetura, basically translates into “spine tail”. This is an accurate description of the bird's tail, as the shafts of all ten tail feathers end in sharp, protruding points. This assists them with vertical perching.

  • Using GIS to Monitor Forest Fragmentation and Designate Wood Thrush Habitat for Conservation Along the Eastern United States
    Using GIS to Monitor Forest Fragmentation and Designate Wood Thrush Habitat for Conservation along the eastern United States By Isabel Esparza Background and Hypothesis The Wood Thrush (Hylocichla mustelina) is a neotropical migratory songbird whose renowned flute-like song can be commonly heard in eastern U.S. forests in the spring through early summer. This beautiful and reclusive bird can be observed thrashing and hopping around the leaf litter on the forest floor, probing for insects to eat. Though this native species is still abundant in the U.S., its numbers are rapidly declining. Reasons for Wood Thrush decline are currently being researched, but hypotheses include increased numbers of brown-headed cowbird (Molothrus ater) nest parasitism, which lowers Wood Thrush nestling survival. Also, the Wood Thrush relies on interior deciduous forest for nesting, and increased habitat fragmentation is diminishing suitable Wood Thrush habitat in the United States (“Wood Thrush” 2013). Habitat fragmentation is the process of breaking down continuous habitat into smaller, isolated patches, thus reducing the overall amount of habitat and producing smaller isolated patches of habitat with decreased interior and increased edge. Increase in edge habitat facilitates the proliferation of invasive species of plants and animals as well as predators. Furthermore, the creation of new edge habitat allows species such as the brown-headed cowbird to infiltrate into habitats which were once interior forest. Wood Thrush thrive in interior forest habitat, and experience decreased success in edge habitats because edge habitats make Wood Thrush nests more vulnerable to predation by raccoons, domestic or feral cats, crows, jays, and the brood parasite brown-headed cowbird.

Nesting Success and Juvenile Survival for Wood Thrushes in an Eastern Iowa Forest Fragment Larkin A. Powell1, Lara J. Scott, and Jason T. Hass ABSTRACT Forests in NE Iowa are highly fragmented, which may affect sustainability and dynam- ics of bird populations. We studied Wood Thrush (Hylocichla mustelina) nesting success at the Mines of Spain Recreation Area near Dubuque, IA during 2001. We also monitored movements of juveniles using radio transmitters during the birds’ initial dispersal from the nest site, and we used DNA analyses to determine their gender. Seventy percent of the nests (n=10) were parasitized by Brown-headed Cowbirds (Molothrus ater). The daily nest suc- cess rate was 0.9612 (SE=0.0189), and daily juvenile survival was 0.9703 (SE=0.0169).

  • Reproductive Success of the Wood Thrush in a Delaware Woodlot
    REPRODUCTIVE SUCCESS OF THE WOOD THRUSH IN A DELAWARE WOODLOT JERRY R. LONGCOREAND ROBERT E. JONES OODLAND habitat in northern Delaware is being altered considerably by urbanization (Catts et al., 1966). These habitat changes are not confined to Delaware but encompass most of the Atlantic seaboard. Changes in land-use priorities stemming from the increasing human population are resulting in the destruction of wooded areas. To evaluate the effects of these changes on wildlife populations, an ecological study of suburban woodlots is under way in the Department of Entomology and Applied Ecology at the University of Delaware. Birds, being conspicuous and common, seemed a logical choice on which to undertake studies. Initially a 35.6-acre relatively undisturbed woodlot was chosen as a basic study unit so that a base line of breeding bird SUC- cess could be established. Information gained on this unit is to be used for comparative purposes with breeding bird success obtained for greatly disturbed, remnant woodlots scattered throughout suburban developments. This paper deals only with the Wood Thrush (Hylocichla mustelina) in the 35.6-acre study unit. In addition to the standard information on breed- ing success; i.e., per cent of nests successful, per cent of eggs hatching, per cent of young fledging, etc., an attempt is made to relate reproductive success to the interplay of the physical and biological factors at work in the woodlot. An analysis of the 142 Wood Thrush nesting attempts recorded over a two-year period is presented. METHODS Systematic nest searches were initiated in mid-May, 1965, and in late April in 1966.
