TL;DR: It is indicated that grassland songbirds were not negatively affected, at least in the short term, by removal of duck nest predators, and changes in the relative importance of predators on removal sites in 1995 suggest that smaller predators that were not targeted by removal efforts (i.e., ground squi...

TL;DR: In this article, the authors investigated correlations between annual climatic indices and weather during the breeding season and the annual survival of Barn Swallows (Hirundo rustica) breeding at 2 sites in North America.

TL;DR: In this article, the authors evaluated natal dispersal patterns in Bicknell's thrush (Catharus bicknelli) across most of the breeding range using a 10-year data set of stable-hydrogen isotope ratios in feathers (δ2HF) grown on the natal area and sampled 1 year later at the first breeding site.

TL;DR: Stable isotope analyses of 39 Arctic marine species to investigate trophic relationships and isotopic niches of the West Greenland food web in 2000–2004 provide new insights into species and functional group interactions, as well as into the food web structure and ecosystem functioning of an important Arctic region that can be used as a template to guide future modelling of carbon, energy and contaminant flow in the region.

TL;DR: This study evaluated if male age and body size, density of conspecifics, and arthropod biomass contributed to variation in territory size and overlap of Ovenbirds, Seiurus aurocapillus, in a fra...
