Least Terns at Heron's Head


I spent three hours doing a predator monitor watch at Alameda Naval Air Station Tuesday evening. There are lots and lots of Least Terns there with lots of chicks. I would imagine they don't take very long to cross the bay in their search for nice small surface fish. I saw lots of feeding of young and some continued ritual mating behaviour--the offering of a fish to a female. I even witnessed a copulation, guess the fish worked!
