UNIDENTIFIED GULLS - KELP-like:

Note that here I include any birds that might possibly be explained by being a KELPxAMHE hybrid, due to the known hybridization event on the Chandeleur Islands of Louisiana between c.1990. and at least 2000. I gather that since then no mixed pairs of pure or F1 birds were detected, and that the colony was in the process of becoming almost entirly AMHEs (or birds with such diluted Kelp input that they were undetectable) until its destruction by Hurricane Katrina in 2005.
