Feeding trial evaluation of supplemental sodium and calcium use by pigeons
Wildlife Society Bulletin, 2023 The Pacific Coast band‐tailed pigeon's (Patagioenas fasciata monilis) conspicuous and well documented use of supplemental minerals has allowed wildlife managers to conduct counts of pigeons at sites with minerals to index their abundance; but despite at ...

King Rail (Rallus elegans) presence in the Midwestern United States is predicted by local-scale factors and avian community. [PDF]
Ecol Evol, 2023 Our study is unique in that it builds occupancy and MaxEnt habitat models for King Rails at multiple spatial scales and incorporates data on the presence of other marsh‐obligate birds. We found that King Rail occupancy was associated with local wetland habitat factors and presence of other rails.

Rarity begets rarity: Social and environmental drivers of rare organisms in cities. [PDF]
Ecol Appl, 2022 Abstract Cities are sometimes characterized as homogenous with species assemblages composed of abundant, generalist species having similar ecological functions. Under this assumption, rare species, or species observed infrequently, would have especially high conservation value in cities for their potential to increase functional diversity.

Chromosome size affects sequence divergence between species through the interplay of recombination and selection. [PDF]
Evolution, 2022 Abstract The structure of the genome shapes the distribution of genetic diversity and sequence divergence. To investigate how the relationship between chromosome size and recombination rate affects sequence divergence between species, we combined empirical analyses and evolutionary simulations. We estimated pairwise sequence divergence among 15 species

Combining point counts and autonomous recording units improves avian survey efficacy across elevational gradients on two continents. [PDF]
Ecol Evol, 2021 Using avian surveys conducted in comparable, high elevation, temperate mountain habitats at opposite ends of the Americas (British Columbia, Canada, and southern Chile), we show combined ARU and point count methods are among the most efficient and accurate approaches to capturing diversity.

AN OBSERVATION OF RECIPROCAL MOUNTING BY THE SPOT-WINGED PIGEON PATAGIOENAS MACULOSA [PDF]
, 2023 Reciprocal mounting, involving heterosexual or same-sex individuals, is a widespread but under-reported behaviour in birds. It is generally accepted that it is an integral part of heterosexual courtship in some bird species, and that it may provide a ...

Hierarchical Bayesian integrated model for estimating migratory bird harvest in Canada
The Journal of Wildlife Management, Volume 86, Issue 2, February 2022., 2022 This integrated hierarchical model provides improved estimates of the hunting activity and harvest of migratory game birds in Canada and new estimates for age‐ and sex‐specific harvest. The Bayesian framework and the open‐source code that we provide will facilitate ongoing improvements and elaborations of the model.

Birds of the Estação Ecológica de Itirapina, State of São Paulo, Brazil [PDF]
, 2008 O cerrado é um dos biomas mais ameaçados no mundo, apresentando algumas das maiores taxas de destruição causadas principalmente pela agropecuária. Poucos estudos têm avaliado a diversidade local de aves no cerrado, especialmente em áreas marginais desse ...

Local Convergence of Behavior across Species [PDF]
, 2021 Behavior is a way for organisms to respond flexibly to the environmental conditions they encounter. Our own species exhibits large behavioral flexibility and occurs in all terrestrial habitats, sharing these environments with many other species.
