Movement, from foraging to migration, is known to be under the influence of the
environment. The translation of environmental cues to individual movement decision making …

Highlights•Timing of reproduction and migration vary within and among populations.•Timing
differences arise from variation in neuroendocrine mechanisms.•Timing differences …

We hypothesized differences in molecular strategies for similar journeys that migrants
undertake to reproduce in spring and to overwinter in autumn. We tested this in redheaded …

The circadian rhythms are involved in the photostimulation of seasonal responses in
migratory blackheaded buntings. Here, we investigated whether changes in daily levels and …

Twice a year billions of birds migrate between breeding and wintering grounds. To facilitate
migrations, birds develop migratory disposition, a complex suite of behavioral and …

Abstract Blue-winged Teal (Anas discors) initiate southward migration from their North
American breeding grounds in late summer, making trans-Gulf flights to overwinter in South …

Prescribed grazing management can have myriad effects on wildlife, with low to moderate
grazing being associated with an increased abundance of some grassland birds …

Migratory animals such as birds are unique in that they change location over the course of
their annual cycle in response to variation in weather and food availability. Many passerine …

A factor common to human-dominated environments, artificial light at night (ALAN), has
become pervasive and disruptive to wildlife. Many species rely on changes in day length to …

Climate change is having a disproportionate impact on the Arctic. For Arctic breeding birds,
basic knowledge of their annual cycle, specifically the timing, route, and movement behavior …
