Abstract Full-annual-cycle (FAC) models integrate seasonal demographic and
environmental processes to elucidate the factors that limit and regulate animal populations …

Migration is typically associated with risk and uncertainty at the population level, but little is
known about its cost–benefit trade‐offs at the species level. Migratory insects in particular …

Conservation of migratory animals requires information about seasonal survival rates.
Identifying factors that limit populations, and the portions of the annual cycle in which they …

Migratory bird species that feed on air-borne insects are experiencing widespread regional
declines, but these remain poorly understood. Agricultural intensification in the breeding …

Technological constraints have limited our ability to compare and determine the proximate
and ultimate drivers of migratory behavior in small-bodied birds. Small VHF transmitters (< …

Grasslands are one of the most imperiled ecosystems worldwide. Conversion to cropland
and desertification, including shrub encroachment, are primary factors behind the loss of …

Background Artificial light is ubiquitous in the built environment with many known or
suspected impacts on birds. Birds flying at night are known to aggregate around artificial …

Aim Migratory species rely on multiple ranges across the annual cycle, rendering them
vulnerable to a wide range of spatially disparate anthropogenic threats. The spatial …

Understanding the factors that limit and regulate wildlife populations requires insight into
demographic and environmental processes acting throughout the annual cycle. Here, we …

Understanding how events during one period of the annual cycle carry over to affect survival
and other fitness components in other periods is essential to understanding migratory bird …
