Resource allocation in breeding seabirds: responses to fluctuations in their food supply
In the vicinity of the Pribilof Islands in the Bering Sea, abundance of food available to surface-foraging seabirds was greater during the chick-rearing period in 1988 than in 1987, whereas abundanceExpand

NEST SITE SELECTION AND NESTING SUCCESS IN SALTMARSH BREEDING SPARROWS: THE IMPORTANCE OF NEST HABITAT, TIMING, AND STUDY SITE DIFFERENCES
Abstract We examined nest-site selection and nesting success in Saltmarsh Sharp-tailed (Ammodramus caudacutus) and Seaside Sparrows (A. maritimus), at seven sites in Connecticut. We found 160Expand

Developing Dynamic Mechanistic Species Distribution Models: Predicting Bird-Mediated Spread of Invasive Plants across Northeastern North America
Species distribution models are a fundamental tool in ecology, conservation biology, and biogeography and typically identify potential species distributions using static phenomenological models. WeExpand

The hummingbird tongue is a fluid trap, not a capillary tube
Hummingbird tongues pick up a liquid, calorie-dense food that cannot be grasped, a physical challenge that has long inspired the study of nectar-transport mechanics. Existing biophysical modelsExpand

Feeding mechanisms: Hummingbird jaw bends to aid insect capture
The upper jaws of birds, unlike those in many tetrapods, move relative to the skull and are often flexible along their length, whereas the lower jaw (mandible) is usually a rigid structure formed byExpand

INVASIVE FRUITS, NOVEL FOODS, AND CHOICE: AN INVESTIGATION OF EUROPEAN STARLING AND AMERICAN ROBIN FRUGIVORY
Abstract We compared the feeding choices of an invasive frugivore, the European Starling (Sturnus vulgaris), with those of a native, the American Robin (Turdus migratorius). Using captive birds, weExpand

  • 1 April 1996
Sexual size dimorphism is widespread in shorebirds, yet no tests of the assumption that such size dimorphism extends to functionally significant dimensions of the bill exist. This report presentsExpand

Testing the function of the domed nests of Saltmarsh Sharp-tailed Sparrows
Saltmarsh Sharp-tailed Sparrows (Ammodramus caudacutus) build ground nests, often with a closely-woven dome, in marshes that frequently flood during high tides. To test the hypothesis that domedExpand
