Abstract Since 2005, the Brazilian Ornithological Records Committee (CBRO) has published
updated checklists of Brazilian birds almost every year. Herein, we present a completely …

There is compelling evidence that A fro‐P alaearctic (A‐P) migrant bird populations have
declined in E urope in recent decades, often to a greater degree than resident or short …

We describe a new collaborative network, the Motus Wildlife Tracking System (Motus;
https://motus. org), which is an international network of researchers using coordinated …

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 …

Once-abundant aerial insectivores, such as the Tree Swallow (Tachycineta bicolor), have
declined steadily in the past several decades, making it imperative to understand all aspects …

Aerial insectivores (birds that forage on aerial insects) have experienced significant
population declines in North America. Numerous hypotheses have been proposed for these …

Ecologists studying bird foraging ecology have generally focused on food quantity over
quality. Emerging work suggests that food quality, in terms of highly unsaturated omega‐3 …

From butterflies to elephants, the rapidly developing science of movement ecology is
providing increasingly detailed spatio-temporal data on a wide array of mobile animals …

Light‐level geolocation data loggers, or geologgers, have recently been miniaturized to the
extent that they can be deployed on small songbirds, allowing us to determine many …

The rise of antibiotic resistance demands the acceleration of molecular diversification
strategies to inspire new chemical entities for antibiotic medicines. We report here on the …
