Give Back Days: Visit Marsh Madness for a Good Cause

Give Back to the Birds Day: Do you have plans for after the The Biggest Week In American Birding? Birds will still be around, with some later migrants coming through like Connecticut!!! What better way to find them than being in the leaf litter helping Friends of Magee Marsh remove invasives on the boardwalk? This will be for just a few hours on a weekday afternoon. We are planning to meet on May 18 and 19th, 2015.    We need to encourage native plant habitat again. It's good for the birds! OOS will be there and your help is needed. Fill out the volunteer application today located on the Friends of Magee Marsh website ( it takes a long time to get approved) and come work and bird with us! 

Will You Accept the Rusty Blackbird Challenge?

Rusty Blackbirds have experienced an 85-99% population drop in the last half-century. Over the last 15 years, research on Rusty breeding and wintering ecology has allowed us to develop conservation strategies to protect this vulnerable species. But many questions still remain, and Rusty Blackbird migration habits are largely a mystery. Are there hot spots where many Rusties congregate during migration? Are similar migratory stopover areas used by Rusties each year, and are these areas protected? The International Rusty Blackbird Working Group, in partnership with eBird, the Cornell Lab of Ornithology, the Smithsonian, and the Vermont Center for Ecostudies, is launching a spring migration Blitz. The objectives of the Blitz are:1. Identify migratory stopover sites; 2. Determine consistency of numbers/timing of Rusty Blackbird migration;3. Strengthen relationships with state and federal agencies in order to advance Rusty Blackbird conservation;4. Engage the birding community and create increased awareness and excitement about Rusty Blackbirds
Go to  to help advance understanding of one of the most rapidly declining landbirds in North America!

Birding Festivals

Looking for a birding festival this summer? Visit the Bird Watcher's Digest  "Festival Finder" page to have look for festivals around the country. This is a great way to get to find birds with local guides and field trips to hotspots in the area, and a fun way to get to know other birders too!

The Passenger Pigeon in Ohio

Passenger Pigeons in Ohio

Historian Caleb Atwater observed in 1838 that passenger pigeons still passed through Ohio in huge numbers in the spring and fall, adding that "[f]ormerly the pigeons tarried here all summer, building their nests, and rearing their young, but the country is too well settled for them now; and so, like the trapper for beaver, and the hunter, they are off into the distant forests, where their food is abundant, and where there is none to disturb them in their lawful pursuits." Actually, large nesting colonies survived in a few spots in the state after the middle of the century, even though there were growing numbers of humans who continued to persecute them. 

By 1882, Wheaton, born in 1840 and author of Report on the Birds of Ohio, observed it had become "much less abundant and irregular." Less than twenty years later its extinction in the wild was complete. Lawrence Hicks in 1935 summed up its former abundance in “immense numbers in every section of the state and presumably breeding generally, though usually locally and in very large colonies,” citing confirmed large nestings historically in rural Licking, Pickaway, Morrow, Huron, Wayne, Medina, Columbiana, Portage, Trumbull, Ashtabula, and Geauga counties. 

Last Records of the Passenger Pigeon:
Still extant is a mounted specimen, now at the Ohio Historical Society in Columbus, collected in the state in 1900, thought for many years to have been the last pigeon verified in the wild.  Martha, a pigeon kept at the Cincinnati Zoo until her death in 1914, is considered to have been the last of all her kind.

Reporting a Rare Bird Sighting

Part of the excitement of birding comes when we find something unusual, something rare or unexpected that we can relish and share with others. But telling others about your finding, in person or on the internet, is fleeting. Even more important, for the ornithological record, is documenting your record in a permanent way. Reports of rarities, when they can be authenticated and published, help to fill out the total picture of our local avifauna. As records, they can help us all to recognize habitats, regions, or seasons in which scarce species are most likely to be found.

Why Submit Documentation?

Any scientific report of an unusual phenomenon must be supported by documentation: that is, verifiable evidence reported and vouched for by a first-hand observer, submitted for peer review before acceptance and publication. In general, the rarer and more interesting the occurrence, the more important it is to document and verify it for the record.
