Summary
BirdNote Daily explores the fish crow, a smaller relative of the American crow distinguished by its nasally call. The episode explains how fish crows differ from American crows, their geographic distribution across the eastern U.S., and their expanding range northward and westward.
Insights
- Fish crows are morphologically similar to American crows but have distinctly different vocalizations that serve as a reliable identification method
- Fish crow populations are expanding their geographic range beyond traditional eastern U.S. territories, suggesting environmental or ecological shifts
- Fish crows demonstrate adaptive behavior by joining mixed-species flocks in urban environments and competing for food resources in cities and landfills
- Understanding bird species identification through distinctive calls increases public engagement with wildlife and environmental conservation
Trends
Geographic range expansion of fish crow populations northward and westwardIncreased presence of fish crows in urban and suburban environments alongside American crowsGrowing public interest in bird identification and species differentiation through audio cuesWildlife adaptation to human-modified landscapes including cities and landfills

Quotes
"The harsh caws of American crows are one of the most familiar bird calls in North America. But a few crows in this flock sound like they've got stuffy noses."
Michael Stein•Opening
"Fish crows are a little smaller than American crows. Otherwise, they look very similar. But their voices are distinctive."
Michael Stein•Mid-episode
"While they do love seafood, fish crows aren't limited to coastal areas. They're found in much of the eastern U.S., and the species seems to be spreading to new areas, north and west, to breed."
Michael Stein•Mid-episode
"So if you hear a bird in your neighborhood that sounds like it could use some cold medicine, keep an eye out for fish crows."
