Global patterns and predictors of avian population density
Abstract Aim How population density varies across animal species in the context of environmental gradients, and associated migratory strategies, remains poorly understood. The recent influx of avian trait data and population density estimates allows these patterns to be described and explored in unprecedented detail.

Bird genetic databases need improved curation and error reporting to NCBI
The ongoing biodiversity crisis is causing rapid species losses faster than taxonomists' capacity to describe new species. Integrative taxonomic approaches need robust taxonomic baseline data to correctly describe and conserve global species diversity, in which genetic data are one of the pillars.

Abstract In several taxa of Neornithes (crown group birds), the lacrimal/ectethmoid complex exhibits small bones, the comparative osteology of which is poorly studied. Some of these ossicles—which are commonly known as uncinate bones (ossa uncinata or ossa lacrimopalatina)—were already described two centuries ago, but knowledge of their distribution ...

Co‐infections: Simultaneous detections of West Nile virus and Usutu virus in birds from Germany
Abstract The emergence of West Nile virus (WNV) and Usutu virus (USUV) in Europe resulted in significant outbreaks leading to avifauna mortality and human infections. Both viruses have overlapping geographical, host and vector ranges, and are often co‐circulating in Europe.

Niche Partitioning of Feather Mites within a Seabird Host, Calonectris borealis [PDF]
According to classic niche theory, species can coexist in heterogeneous environments by reducing interspecific competition via niche partitioning, e.g. trophic or spatial partitioning.

The eggshell structure in apteryx; form, function, and adaptation
Apteryx incubates its eggs for 74 days in a ground burrow. The eggshell structure reveals adaptations to this type of environment, and in relation to the climate, the eggshell has been laid in. Abstract Apteryx is a genus of flightless birds endemic to New Zealand known to lay very large eggs in proportion to body weight.

A partir de los movimientos de un pájaro... La «danza de la perdiz» en los rituales ganaderos de los Andes peruanos [PDF]
This paper presents a brief look at the conception of a bird that the people of the central Andes of Peru have. We explore this perspective through the collective representations found in a ritual and in beliefs and stories about this animal in the ...

Captive-born collared peccary (Pecari tajacu, Tayassuidae) fails to discriminate between predator and non-predator models [PDF]
Captive animals may lose the ability to recognize their natural predators, making conservation programs more susceptible to failure if such animals are released into the wild.
