Ring-billed Gull (leucistic)

Description:

Typical size and shape of common ring-billed gull. All-feathers.

Habitat:

Pond at city park.

Notes:

Discussion of albinism/ leucism in birds: http://www.birds.cornell.edu/pfw/AboutBi... "Typically birds with abnormally white feathers do not survive long because they are so much more visible to predators. Those that do survive may have trouble attracting a mate. Consequently, the mutated genes that cause albinism and leucism are less likely to be passed on to a new generation."
