Understanding animal movement is essential to elucidate how animals interact, survive, and
thrive in a changing world. Recent technological advances in data collection and …

We present an overview of the global spatiotemporal distribution of avian biodiversity,
changes in our knowledge of that biodiversity, and the extent to which it is imperilled. Birds …

Bird migrations are impressive behavioral phenomena, representing complex
spatiotemporal strategies to balance costs of living while maximizing fitness. The field of bird …

Many birds fly non-stop for days or longer, but do they sleep in flight and if so, how? It is
commonly assumed that flying birds maintain environmental awareness and aerodynamic …

Technological advances in recent years have seen an explosion of tracking and stable
isotope studies of seabirds, often involving repeated measures from the same individuals …

Soaring birds often rely on ascending thermal plumes (thermals) in the atmosphere as they
search for prey or migrate across large distances,,–. The landscape of convective currents is …

The extraordinary adaptations of birds to contend with atmospheric conditions during their
migratory flights have captivated ecologists for decades. During the 21st century …

Soaring migrant birds exploit columns of rising air (thermals) to cover large distances with
minimal energy. Using social information while locating thermals may benefit such birds, but …

Single-cell RNA sequencing (scRNA-seq) has been developed for characterizing the
transcriptome of cells that are rare but of biological significance. With cell barcoding and …

Despite being a prominent aspect of animal life, sleep and its functions remain poorly
understood. As with any biological process, the functions of sleep can only be fully …
