Scoping June

Shorebirds and late Neotropical migrants are wrapping up the spring migration in the first week or so of June. Local breeding birds are busy nest building and rearing future generations. Now is the time to catch up with birds you may have missed during spring migration!

The Iroquois NWR complex is high priority on many birder's itineraries this time of year. Species such as Cerulean and Prothonotary Warblers which are rare to stumble upon during migration can be found breeding within the swamps and wet woods of Iroquois. Black Terns are hawking insects and looking immaculate in their high breeding plumage. Cayuga Overlook is a great spot to observe these terns. On quiet mornings, visitors may hear the call of Least Bitterns in the cattail marshes.

Two other species that breed locally but are rarely seen during migration are Louisiana Waterthrush and Acadian Flycatcher. These two species can be found near the Eternal Flame at Chestnut Ridge SP in Orchard Park, NY. Broad-winged Hawks nest in this forest as well.


The Buffalo Ornithological Society, Inc. (BOS) was established in 1929 to promote the study of the birds of the Niagara Frontier Region. Annual grants are awarded by the BOS to fund member-sponsored avian research projects. We are proud of our extensive scientific research databases, our continuing involvement in environmental and conservation activities that impact birds, and our promotion of the enjoyment of ornithology.

The BOS coverage area includes Western New York and parts of nearby Ontario, Canada. This region is rich in bird life with over 380 species and 25 recognizable subspecies of birds recorded. Explore our site to learn more about where to report and find birds, both regional specialties and rare visitors.

The Buffalo Ornithological Society has something to offer to anyone passionate about birds: from the backyard feeder- watcher, the avid lister or the environmental activist, to the dedicated citizen scientist or the professional ornithologist. Society activities include regular programs, field trips, intensive long-term bird counts, checklist and date guide development, varied research activities, and involvement in local conservation efforts. We invite you to join in the activities of the society!

I like the BOS… where else will you find others who like to hang out in garbage dumps and wastewater plants?
