Flamingoes are gregarious wading birds, usually 3 to 5 feet (0.9 to 1.5 m) tall, found in both the Western and Eastern Hemispheres. Flamingos filter-feed on shellfish and algae. Their oddly shaped beaks are adapted to separate mud and silt from the food they consume and, uniquely, are used upside-down. One species has been recorded in Virginia.

A 2005 molecular study reviewed segments of DNA of the common raven and found that Chihuahuan raven are genetically nested within common ravens based on mitochondrial DNA. That is, common ravens from the California clade are more similar in mtDNA to Chihuahuan ravens than they are to common ravens in the Holarctic Clade. [4] [5]

The pied raven had large areas of white feathering, most frequently on the head, the wings and the belly, and its beak was light brown. Apart from that, it looked like the all-black North Atlantic ravens (C. c. varius morpha typicus), [3] which remain widespread in the Faroe Islands and are also found in Iceland. [4]
