Guest feature | Sora research and morphometrics on the Patuxent River, Maryland
Nestled near the middle of the Patuxent River stands Jug Bay — the largest freshwater tidal wild rice (Zizania aquatica) marsh in Maryland. It boasts a unique and rich history intertwined with the region’s abundance of migrating Sora (Porzana carolina). These elusive birds have drawn hunters to the Patuxent for over 200 years. Historical logs from local gun clubs paint a vivid picture of Jug Bay's allure, including one staggering account of just three hunters, from one of the clubs, bagging a remarkable 1,800 Soras in six hours.

Guest feature | New information from old tags: getting the most out of geolocator data
Just about every bird nerd I know loves a good tracking study. As tracking tags have gotten lighter, we’ve been able to deploy them on more and more species. The movements they have uncovered have confirmed suspected migratory routes in some cases and completely flipped those expectations on their head in others. But regardless, the information we gather from tracking tags are both exciting to read about and invaluable to protecting migratory birds. Read More
Guest feature | Unveiling the secrets of the breeding season in Broad-winged Hawks: home range size and site fidelity
When studying avian breeding ecology, the first questions that come to our minds are: where does the bird breed? How much space does it need? Does it change annually? Indeed, understanding home range size, and identifying the habitat features influencing it, is key to addressing potential conservation issues. Read More

Guest feature | Northern Bobwhite (Colinus virginianus) breeding season roost site selection in a working agricultural landscape in Clay County, Mississippi
Northern bobwhite (Colinus virginianus) have been considered a beloved gamebird of the North American hunter for generations. Unfortunately, bobwhite populations are experiencing range-wide population declines. By the early 1990s, bobwhite populations declined by 60-80% throughout approximately 70% of their range. Read More
AFO news | Statement on common name changes
The Association of Field Ornithologists (AFO) strongly endorses efforts to increase diversity, equity, and inclusion in the field of ornithology and the pastime of birding. The recent decision by the American Ornithological Society to change all eponymous bird names caused a stir in much of the ornithological community. We have had many discussions among AFO […] Read More
Guest feature Studying | Bird Migration without ever capturing a single bird
The ability to attach devices such as satellite transmitters or geolocators to birds has transformed our knowledge of how birds migrate. However, these technologies have their limits. They require capturing the birds, usually twice, and the expense limits most studies to a small number of individuals within a relatively limited portion of their range. Also, some species, such as the Ruby-crowned Kinglet, are too small to allow tagging with current geolocators. Read More
Guest feature | Long-term changes in arrival timing and site functionality in two passerine species during spring migration in northeastern Pennsylvania, USA
We have been studying migratory songbirds for more than 18 years in and near Lackawanna State Park in Lackawanna County Pennsylvania, USA. Over the years we have examined a number of questions, mostly focused migration. In addition to capturing and banding birds for identification, we take assorted morphological measures, weigh, age (via plumage and measurements), and sex […] Read More
