Mid-summer arrival by Blue Grosbeaks at the northern extent of their breeding range: evidence for dual breeding?

Mid-summer arrival by Blue Grosbeaks at the northern extent of their breeding range: evidence for dual breeding?

Posted on by David Swanson
On my morning running route through farmland with shrubby field borders in southeastern South Dakota, I noticed that Blue Grosbeaks often first showed up in the area on approximately July 1st. This arrival pattern seemed odd and different from arrival patterns of typical migrants in this habitat, such as Dickcissel, Indigo Bunting, Field Sparrow and Orchard Oriole... Read More

Diverse patterns of migratory timing, site use, and site fidelity by Alaska-breeding Whimbrels

Documenting the ecology of Cerulean Warblers in the understudied Ozark region

Posted on by Jacob Wessels
Cerulean Warblers (Setophaga cerulea) are a Nearctic-Neotropical migratory songbird species in decline. During the breeding season, Cerulean Warblers nest in deciduous forests of the eastern United States and Canada. Over about the last twenty years, much research has focused on improving our knowledge of the biology of this species to inform conservation and reverse this decline. Read More

Bergstrom Award helps Ph.D. student with research on threatened grassland birds in Argentina

When I was awarded my Ph.D. grant I was filled with excitement and joy as I would be able to study some of the most iconic bird species of northeastern Argentina’s vast grasslands: the Strange-tailed Tyrant (Alectrurus risora), the Black-and-white Monjita (Xolmis dominicanus), the Tawny-bellied Seedeater (Sporophila hypoxantha), and the recently described Iberá Seedeater (S. iberaensis).

The professional ornithological societies of the Americas have come together in solidarity with a statement affirming our commitment to maintaining the safety of everyone participating in ornithological field activities or exploring the natural world.
