Selective alarm call mimicry in the sexual display of the male superb lyrebird (Menura novaehollandiae)

Taylor L. Crisologo, Sarah A. Dzielski, James R. Purcell, Michael S. Webster et autres

Abstract Despite much research on mimicry, little is known about the ecology of dynamic mimetic signals involving mimicry of multiple species. Some of the most conspicuous examples of phenotypically plastic mimicry are produced by oscine passerines, where vocal production learning enables some …

Supplemental feeding of insect larvae increases mass of nestling Eastern Bluebirds, but not nestling Black‐capped Chickadees

Sarah A. Dzielski, Robyn L. Bailey, Facundo Fernandez‐Duque, David N. Bonter

Globally, billions of U.S. dollars are spent annually to provide food for wild birds. The variety of foods offered continues to diversify, yet the consequences for wildlife of this widespread human activity are relatively unexplored, as are the relative benefits of different …

Emergent Freshwater Insects Serve as Subsidies of Methylmercury and Beneficial Fatty Acids for Riparian Predators Across an Agricultural Gradient

Cornelia W. Twining, N. Roxanna Razavi, J. Thomas Brenna, Sarah A. Dzielski et autres

Aquatic-to-terrestrial subsidies have the potential to provide riparian consumers with benefits in terms of physiologically important organic compounds like omega-3 long-chain polyunsaturated fatty acids (n-3 LCPUFAs). However, they also have a “dark side” in the form of exposure to toxicants such as …

Helpers at a Sapayoa nest are kin

Benjamin M. Van Doren, Jack P. Hruska, Sarah A. Dzielski, Bronwyn G. Butcher

The natural history of the Sapayoa Sapayoa aenigma, the sole member of the Sapayoidae and the only New World representative of the ‘Old World suboscines’, is poorly known. Previously, we reported a pair of adult Sapayoas breeding with assistance from two immature …

Habitat-specific divergence of air conditioning structures in bird bills

Raymond M. Danner, Eric R. Gulson‐Castillo, Helen F. James, Sarah A. Dzielski et autres

We used high precision computed tomography (CT) and traditional radiography to study the nasal conchae, complex structures within the nasal cavity that condition air via countercurrent heat exchange. Air conditioning in the conchae assists thermoregulation and water balance, both of which pose …

Reproductive biology of the Sapayoa (Sapayoa aenigma), the “Old World suboscine” of the New World

Sarah A. Dzielski, Benjamin M. Van Doren, Jack P. Hruska, Justin M. Hite

The Sapayoa (Sapayoa aenigma), a low-density resident of Chocó rainforests from Panama to Ecuador, has long perplexed ornithologists. It was originally described as a manakin (Pipridae), but molecular work has revealed its closest living relatives to be Old World suboscines (Eurylaimides) and …
