Between-Year Survival and Rank Transitions in Male Black-Capped Chickadees (\u3cem\u3ePoecile Atricapillus\u3c/em\u3e): A Multistate Modeling Approach [PDF]
, 2008 In dominance-structured animal societies, variation in individual fitness is often related to social status. Like many passerine birds, Black-capped Chickadees (Poecile atricapillus) have a short average adult life-expectancy (Ø2 years); however, the ...

Ibis, EarlyView.Detailed knowledge about bird migration patterns can enhance our understanding of the evolution of migration and temporal changes in space use throughout the annual cycle. Additionally, as many migratory bird species are experiencing population declines, understanding the connectivity between their spatial distributions during breeding, migration and ...

Vectors and Vector‐Borne Diseases: Biology, Epidemiology and Integrated Control Strategies
Journal of Applied Entomology, EarlyView.ABSTRACT Vector‐Borne Diseases (VBDs), transmitted by arthropods such as mosquitoes, ticks, fleas and sandflies, represent a significant threat to global health. These diseases can be caused by a variety of pathogens, including bacteria, viruses, protozoa, and helminths.

Journal of Anatomy, EarlyView.Juvenile scolopacid shorebirds possess well‐developed osteological correlates of tactile bill‐tip organs, indicating sensory systems for remote‐touch foraging are present from early life. Ontogenetic changes in bill‐tip morphology suggest ecological specialisation and interspecific variation develop later, after fledging in these highly precocial ...

Radar studies of bird migration [PDF]
Observations of bird migration with NASA radars were made at Wallops Island, Va. Simultaneous observations were made at a number of radar sites in the North Atlantic Ocean in an effort to discover what happened to those birds that were observed leaving ...

Elevation, rather than land use, causes important dietary shifts in the Mediterranean golden eagle
Journal of Zoology, EarlyView.In an ever‐changing landscape, golden eagles in the Iberian Peninsula demonstrate remarkable dietary adaptability. We monitored 50 distinct breeding events over 4 years using camera traps, collecting over 520 000 images. Elevation, rather than land use, emerged as the main driver of prey composition: lagomorphs and columbiforms dominated at lower ...

Contrasting mechanisms driving the northward expansion of African raptors in Europe
Journal of Zoology, EarlyView.Recent climate warming and landscape changes are enabling African raptors to reach Europe through contrasting mechanisms. Using species distribution models, we show that the Atlas Long‐legged Buzzard expands northward following climatic suitability, whereas African vultures reach Europe despite low climatic favourability through socially mediated ...
