The Ornithological Council is updating the Guidelines to the Use of Wild Birds in Research – and we need your help! The Ornithological Council is planning a minor revision to the Guidelines to the Use of Wild Birds in
Warblers are what they eat: Distinctive morphologies influence dietary variation among coexisting species Thinking about dietary specialization in birds may elicit images of raptors carrying animals in their sharp, curved beaks or shorebirds using their long, slender bills to
Only long-term field data can capture nature’s stealthy rarities A tiny crested tit snags a spider from under a twig, shaking the icy needles of a branch tip far above the ground. A lightning fast swoosh, smack! … a
There are many that I like, but this one is mine: A single resource predicts territory occupancy in a population of Peruvian Plantcutters Habitat selection is the process in which organisms choose and avoid features of the environment, ultimately
Grad student experience from a Latin American Bergstrom awardee Click here to view the article in Spanish I could come up with a long and boring lecture picturing how my 5-year PhD came together. Opposite to that, the picture of
Conventional and network analyses of song organization and complexity in northern House Wrens (Troglodytes aedon parkmanii) One important enduring issue in birdsong research concerns the functional value of song diversity. There is particular interest in how species with large
Fledgling Bachman’s Sparrows in a longleaf pine ecosystem: survival, movements, and habitat selection Bachman’s Sparrow is a species of conservation concern throughout many parts of its breeding range and is strongly associated with the fire-dependent longleaf pine ecosystems in
In the hot seat: Mexican Spotted Owl habitat could dry up in the face of climate change Global climate change represents a growing conservation threat, but our understanding of the effects of climate change remains limited for most species. Understanding
Citizen-science recordings prove to be a useful tool in detecting diel patterns in birdsong When listening to birds sing, we often wonder: what are they “saying”? To whom are they singing? For decades, researchers have extensively studied birdsong and the
Do you sing like I do? Geographic variation in the vocalizations of a Neotropical sparrow species complex Variation in phenotypic traits are common in geographic scenarios, and conspicuous when geographic isolation is involved. Genetic, morphological and cultural traits are all
