As the availability of natural nesting habitat for Bank Swallows (Riparia riparia) continues to decline, operational aggregate (sand and gravel) pits have begun to provide alternative nesting habitat. With best management practices being develop[...]

For signal divergence to drive speciation, receivers should perceive structural differences in divergent signals; similar-structured signals from closer relatives are expected to elicit stronger responses than dissimilar signals from distant rel[...]

For species with declining populations across their range, such as Lewis’s Woodpeckers (Melanerpes lewis), understanding habitat selection and its influence on reproductive outcomes are critical for effective management, especially in human-modi[...]

The value of saline lakes and associated wetlands as habitats in the xeric Great Basin is dependent on having water of sufficient quantity and quality to support wetland-dependent birds. To inform conservation and management of these habitats, m[...]

Studies of geographic variation in bird song can provide important insights into vocal evolution. An intraspecific approach, focused on a single species with a broad distribution, can be particularly helpful in understanding the diverse selectiv[...]

The Guineo-Congolian “rain” forest (G-C forest) in West and Central Africa is threatened by deforestation. From 1975 to 2013, the extent of the G-C forest decreased by 37%, from about 131,000 to 83,000 km2. Overall, 46% of bird species in the G-[...]

The study of avian nesting biology in North America and Europe has a long history, resulting in an expansive and information-rich literature. In contrast, the tropics have been relatively neglected and, in most ways, we are still at the frontier[...]

Recently fledged birds often experience low survival as they undergo rapid changes in their behavior, (e.g., habitat use, mobility, and foraging rate). For species of conservation concern, information about the post-fledging period can be critic[...]

The Kohala volcano is home to the most spatially isolated population of Hawaiian forest birds on Hawai‘i Island and contains one of the few native bird populations in the state that has not been monitored since the original Hawai‘i Forest Bird S[...]

The biotic and abiotic environments in bird nests change during the nesting cycle as eggs are laid and incubated and nestlings develop and eventually fledge. Nest-arthropod communities have been studied for many bird species and are commonly sam[...]

Demographic studies of many bird species are challenging because their nests are cryptic, resulting in few nests being found. To maximize statistical power, methods are needed that minimize disturbance while yielding as much information per nest[...]

Few investigators have examined in vivo bite-force of birds, likely due, at least in part, to the difficulty in accessing suitable force transducers. We describe a low-cost, easy-to-build, and portable force transducer with the goal of encouragi[...]

Hummingbirds in North America are currently experiencing contrasting population changes, and little is known about the factors contributing to these changes. We examined the demography of two species and one genus of hummingbirds in western Nort[...]

Within-breeding season movements have not been quantified for Snowy Plovers (Charadrius nivosus) breeding on the Southern Great Plains (SGP), where suitable breeding habitat can range from less than 10 km to more than 600 km apart. This mosaic d[...]
