The California Least Tern, shown here, is on the endangered species list. The idea here is to launch as many fledglings as possible so if global warming does comes to pass the population will be as large as possible[it's the conservative thing to do]. The San Diego Audubon in cooperation with the US Department of Fish and Wildlife and the City of San Diego has set aside five tern nesting areas of which Mariner's Point is the most active with over 100 active nests.
Here I am during a Ternwatcher shift at Mariners Point in San Diego's Mission Bay on Wednesday morning.
