Abstract

We radio-tracked Summer Tanagers (Piranga rubra) at a Gulf coast stopover site to study en route activity budgets. Tanagers were inactive a majority of the time, with scanning, foraging, and preening being the next most commonly observed activities. When foraging, tanagers primarily used sallying to capture a variety of insect prey. Possible explanations for inactivity during stopover include the need for rest following prolonged flight, muscle repair, reduced digestive capacity, and the short distance remaining to the breeding grounds.
