Here's an immature Heermann's Gull (Larus heermanni) that I photographed in La Jolla this morning. Another photographer ID'ed it first and when I passed the knowledge on, one lady replied "Oh! That's a lifer for me!" — the Audubon Society's Bird Festival is in town! :D
This little cutie is a Black Turnstone (Arenaria melanocephala). They have a VERY beautiful pattern on the upper side of their wings, which is only visible in flight. I lacked the motivation and dedication to try and photograph it, today. :P Maybe some other time...
These two are Royal Terns (Thalasseus maximus) — the bird in focus is in non-breeding plumage, with a white forehead; the bird in the background has the black breeding plumage on the head.
This Spotted Sandpiper was fun to watch, as it did its bouncy "dance moves" and then got down really low, sneaking up on some tiny bug (he successfully caught it!). :)
This is a juvenile Western Gull, for comparison with the first photo in this thread. Its plumage is more checkered and the feet are pink instead of dark grey on the juvenile Heermann's Gull.
These are the tide pools near "Hospital Point" in La Jolla, San Diego County — they're very popular with photographers because of the endless variations in the rocks that make for nice foreground in pictures. :)
I really liked how the sunset reflects on the wet rocks.
When we have negative tides some strange and otherwise inaccessible parts of the immediate coast become temporarily accessible. These are the cliffs near the "sea caves" between La Jolla Shores and La Jolla Cove. The magenta color on the rocks comes from, as far as I know, algae.
