Spring tree species use by migrating Yellow-rumped warblers in relation to phenology and food availability.(Report)
Sep 01, 2009; Strode, Paul K. ... Global climate change has affected the phenology of many biological events (Root et al. 2003, Parmesan 2006, Rosenzweig et al. 2008). Long-term data over the last 40-100 years in Europe and North America show advancing phenological events including earlier spring flowering (Bradley et al ....
Habitat selection by Cerulean Warblers in eastern Kentucky.(Report)
Sep 01, 2009; Hartman, Patricia J. ... The Cerulean Warbler (Dendroica cerulea) is a neotropical migratory songbird that has gained widespread attention as a species of conservation and management concern. It breeds in mature, deciduous forests of eastern North America and has experienced range-wide declines over the last 40 ...
Nest-site selection and nest survival of early successional birds in central Pennsylvania.(Report)
Sep 01, 2009; Schill, Katie L. ... Many neotropical migrant bird species in the northeastern United States are experiencing population declines (Sauer et al. 2008). Those using early successional habitats appear to be at particularly great risk, perhaps because of habitat loss due to forest maturation (Askins 1993, ...

Nesting habitat use by Common Eiders on Stratton Island, Maine.(Report)
Sep 01, 2009; Donehower, Christina E. ... Non-random distribution of animals among available habitats is often cited as evidence of habitat choice, a product of natural selection (Burger 1987, Clark and Shutler 1999). The choice of where to breed can have important consequences for reproductive success (Misenhelter and Rotenberry ...
Observations on the breeding biology of the Silky-tailed Nightjar (Caprimulgus sericocaudatus mengeli).(Report)
Sep 01, 2009; Wilkinson, Fiona A. ... The behavior and ecology of most nightjars and nighthawks (Family Caprimulgidae) are poorly known resulting from their largely crepuscular and nocturnal habits. They are difficult to locate and monitor, especially in complex habitats (e.g., rainforests) and only limited data about their ...
Incubation in Great Tinamou (Tinamus major).(Report)
Sep 01, 2009; Brennan, Patricia L.R. ... Uniparental male care has been associated with a variety of mating systems including monogamy, polyandry, and polygynandry (Handford and Mares 1985). The Tinamidae is the largest family of birds where exclusive male parental care is known to occur. However, the breeding biology of most ...
Egg laying, egg temperature, attentiveness, and incubation in the Western Bluebird.(Report)
Sep 01, 2009; Wang, Jennifer M. ... Timing and duration of egg-laying bouts have been mostly studied in open-cup or groundnesting species that are amenable to direct observation (Wiebe and Martin 1995, Oppenheimer et al. 1996, McMaster et al. 1999). Egglaying times are commonly estimated by visiting a nest before and after a ...
Spatial ecology of breeding Least Bitterns in northwest Missouri.(Report)
Sep 01, 2009; Griffin, Amanda D. ... The Least Bittern (Ixobrychus exilis) is currently classified as vulnerable in Missouri (Missouri Natural Heritage Program 2006) and a Region 3 priority species by the U.S. Fish and Wildlife Service (USDI 2002). Much of this species' wetland habitat has been lost over the past 80 years as ...
Estimation of avian population sizes and species richness across a boreal landscape in Alaska.(Report)
Sep 01, 2009; Handel, Colleen M. ... The vast boreal region of North America encompasses a quarter of the world's remaining intact forests and is estimated to support 50% or more of the entire breeding population of at least 98 species of birds (Blancher and Wells 2005). A substantial amount of avian research has been ...
Breeding bird response to field border presence and width.(Report)
Sep 01, 2009; Conover, Ross R. ... Grassland birds have exhibited more significant and consistent population declines than any other avian guild highlighting the urgency for conservation action (Peterjohn and Sauer 1999, Brennan and Kuvlesky 2005). These declines in the United States have largely resulted from extensive ...
Breeding seasons, molt patterns, and gender and age criteria for selected northeastern Costa Rican resident landbirds.(Report)
Sep 01, 2009; Wolfe, Jared D. ... Temporal patterns of molt and breeding seasonality are largely unknown for many resident tropical species (Dickey and van Rossem 1938, Snow and Snow 1964, Snow 1976) in contrast to Nearctic-Neotropic migrants (hereafter 'migrants'). One might assume differential molt sequences and extent ...
Vocal repertoires of auklets (Alcidae: Aethiini): structural organization and categorization.(Report)
Sep 01, 2009; Seneviratne, Sampath S. ... Vocal and other animal displays typically are correlates of speciation and population divergence (Lanyon 1969; Payne 1986; Martens 1996; Price and Lanyon 2002; Isler et al. 2005, 2007), and are used routinely in modern species-level systematics (Cuervo et al. 2005, Athreya 2006, Gonzaga et ...
Foraging behavior of Tufted Tit-Tyrants (Anairetes parulus) in semiarid northcentral Chile.(Report)
Sep 01, 2009; Engilis, Andrew, Jr. ... The Anairetes (Tit-Tyrant) flycatchers of South America inhabit dense scrublands and forested regions from southern Colombia to Patagonia; one species is endemic to the Juan Fernandez Islands (Ridgely and Tudor 1994). Six species are included in the genus (Ridgely and Tudor 1994, Roy et ...
Wintering Yellow-bellied Sapsucker time activity budgets in east Texas bottomland hardwood forests.(Report)
Sep 01, 2009; Speights, Jason R. ... The Yellow-bellied Sapsucker (Sphyrapicus varius) is a migratory woodpecker that winters in the southeastern United States, through east and south Texas, Mexico, the West Indies, and south to northern South America (Walters et al. 2002). Yellow-bellied Sapsuckers excavate and maintain ...
High mountain lakes provide a seasonal niche for migrant American Dippers.(Report)
Sep 01, 2009; Garwood, Justin M. ... Study of avian migratory strategies has been of intense interest to ornithologists, especially when bird species exhibit broad variation in seasonal habitat use (Alerstam 1990). Many species of passerines make seasonal altitudinal migrations to high elevation habitats during spring and ...
Survival rates and lifetime reproduction of breeding male Cooper's Hawks in Wisconsin, 1980-2005.(Report)
Sep 01, 2009; Rosenfield, Robert N. ... Survival is a fundamental attribute in understanding population ecology of avian species as well as trade-offs that may exist among other life history traits, including increased reproduction versus decreased survival (Ricklefs 1973). Information on survival is difficult to obtain (Newton ...
Nomenclatural history and a new name for the Blue-winged Warbler (Aves: parulidae).(Short Communications)(Report)
Sep 01, 2009; Olson, Storrs L. ... This convoluted tale begins in the pre-Linnean times of Mark Catesby (1731: plate 61 and its text), who described and illustrated what he called "The Pine Creeper," with the descriptive Latin phrase Parus americanus lutescens. His illustration, probably drawn from birds obtained near ...
Additional data on the occurrence of the plantaris muscle in the Hawaiian finches (Carduelinae: Drepanidini).(SHORT COMMUNICATIONS)(Report)
Sep 01, 2009; Olson, Storrs L. ... Raikow (1976; 1977a,b; 1978) found great uniformity in the appendicular musculature of the Hawaiian finches, or honeycreepers, of the tribe Drepanidini, subfamily Carduelinae, which he interpreted as providing strong evidence for a monophyletic origin of the group. The only consistent ...
