Food Availability Cannot Explain Dispersal and Settlement Decisions of a Grassland Bird
We test a commonly assumed explanation for animal movements—namely that food availability shapes where animals disperse to. Based on the results of four strong predictions, 3 years of data, and hundreds of individual birds, we show that food cannot explain breeding dispersal in this system, and we propose alternative explanations consistent with our ...

Prospecting Western Bluebirds demonstrated a strong response to public information simulating reproductive success within nest boxes deployed in agricultural systems, but this initial attraction did not translate to increased box selection the following breeding season.

Comparative foraging ecology of lynx and coyotes in three Gulf of Alaska national parks
Abstract Consumers exhibit varying degrees of dietary specialization, with foraging strategies shaped by both evolutionary history and local food availability. In boreal systems, Canada lynx are considered snowshoe hare specialists, whereas coyotes are classically generalist foragers capable of exploiting diverse resources.

This study investigated the distribution of 29 legacy and emerging per- and polyfluoroalkyl substances (PFASs) in soil, nettles, invertebrates, and plasma and feathers of great tits (Parus major) of a terrestrial ecosystem near a fluorochemical plant ...

This paper provides tips on various aspects of organizing a songbird rehabilitation program. Whether one works in a large center with several volunteers or is a home–based rehabilitator, developing procedures, protocols, and policies helps one manage each day more productively and provides continuity of care for each songbird patient.

Partner fidelity is a key component of reproductive strategies in socially monogamous species, yet its adaptive value remains context dependent and poorly understood outside environments with short breeding seasons. In most bird species, partners may remain together or re‐pair between successive nesting attempts, but it remains unclear which components

Although there is abundant evidence that timing of spring migration in landbirds is influenced by annual variation in temperature and longer-term warming due to climate change, much less is known about how these factors influence fall migration ...

Niche partitioning is important for the coexistence of closely related species, allowing species to reduce overlap in resource use despite shared ecological requirements. In alpine environments, harsh climatic conditions and low habitat complexity constrain opportunities for ecological segregation, making seasonal resource fluctuation especially ...

Our study contributes to our understanding of the effects of interspecific competition in species with biparental care where male and female parents must somehow coordinate their response to interspecific competition. Abstract Interspecific competition is an important evolutionary driver of many species' life histories and behaviours, arising wherever ...
