Nearly 300 species of landbirds, whose populations total billions, migrate between the
Neotropics and North America. Many migratory populations are in steep decline, and …

In 2007, the first miniature light-level geolocators were deployed on small landbirds,
revolutionizing the study of migration. In this paper, we review studies that have used …

Geolocator accuracy varies, depending on bird behavior, geographic location, habitat, and
weather (Fudickar et al. 2012, Lisovski et al. 2012). Ground truthing at multiple sites prior to …

Migration movements connect breeding and non-breeding bird populations over the year.
Such links, referred to as migratory connectivity, have important implications for migratory …

Many migratory animals are experiencing rapid population declines, but migration data with
the geographic scope and resolution to quantify the complex network of movements …

There is an overdue and urgent need to establish patterns of migratory connectivity linking
breeding grounds, stopover sites, and wintering grounds of migratory birds. Such …

Juvenile songbirds on spring migration travel from tropical wintering sites to temperate
breeding destinations thousands of kilometres away with no prior experience to guide them …

Understanding migratory connectivity is critical for interpreting population dynamics,
seasonal interactions, and for the implementation of conservation strategies of migratory …

Populations of most North American aerial insectivores have undergone steep population
declines over the past 40 years but the relative importance of factors operating on breeding …

One of the greatest challenges to informed conservation of migratory animals is elucidating
spatiotemporal variation in distributions. Without such information, it is impossible to …
