SOUTHERN BLACK-BACKED GULL (Larus dominicanus)
The Southern Black-Backed Gull (or kelp gull) is about 24 inches long, and adults are white with a black back. However the juveniles look very different, as can be seen below. It is a gull of the southern hemisphere. This gull is omnivorous which includes being also a scavenger. High numbers of them near landfills is not a good environmental sign. Those birds have also been observed pecking into the blubber of live whales, leaving them with large open sores.
