For every season, or at least every Summer, we have migrating terns on the California coast. I found a nice group of terns in the lagoon on Pescadero Creek near the ocean beach this morning. Lots of Caspians, and a few not-a-Caspians. I'm pretty sure that I have a couple decent pictures of Elegant Terns, which are a new bird for me. I am a little challenged by sorting out what appear to be a fair number of juvenile Elegants and Caspians in the mix. Here are a few of the better photos, I'd appreciate help from the experts here which ones are which.
#1 and #2, juvenile Elegant (yellow legs) with adult Caspian
#3 two juvenile Caspians (yellow beaks but black tipped) with an adult Caspian
#4 busy shot, but I think: most are Caspians, especially the clear top bird; the left bird is an adult Elegant (yellow beak, no dark underwing tips, forked tail), along with the blurrier lowest bird
#5 two adult and two juvenile Elegants; the beak on the more central adult looks freakishly long and narrow here
Do I have the hang of Elegant Terns yet?
