Here is another Gull from the Sea of Cortez, now taken perching in a fishing boat.
Note:
Is a gull resident in the United States and Mexico. Of the current population of about 150,000 pairs, 90% nest on the island of Isla Rasa off Baja California in the Gulf of California, with smaller colonies as far north as California and as far south as Nayarit. After breeding, birds commonly disperse to central California, and less commonly north as far as British Columbia and south as far as Guatemala. They are usually found near shores or well out to sea, very rarely inland.
Heermann's Gull sometimes pirates prey from other seabirds, particularly Brown Pelicans, with which it often associates.
Isla Rasa was declared a sanctuary in 1964, and egg-collecting and disturbance during the breeding season are discouraged. Current threats to this gull include the effects of weather on prey species. |
