About the Fish Crow

The fish crow (Corvus ossifragus) is a species of crow associated with wetland habitats in the eastern and southeastern United States. The fish crow was given its binomial name by the Scottish ornithologist Alexander Wilson in 1812, in the fifth volume of his American Ornithology. The binomial is from Latin; Corvus means "raven", while ossifragus means "bone-breaker". It is derived from os or ossis, meaning "bone", and frangere, meaning "to break". The English-language common name fish crow also derives from Wilson, who ascribed the name to the crow's aquatic diet, as described to him by local fishermen. He distinguished the fish crow from John Bartram's great seaside crow by the former's diminutive size when compared to the American crow.

The fish crow's taxonomic relation to other species of the Corvus genus is still poorly understood, but DNA sequencing indicates that it is most closely related to the Hispaniolan palm crow (C. palmarum) and the Jamaican crow (C. jamaicensis), with the three species forming a Nearctic clade. The Sinaloa crow (C. sinaloae) and Tamaulipas crow (C. imparatus) bear morphological similarities to and were once considered conspecific... Wikipedia →
