The Slough is one the San Diego's birding hotspots. I can't believe I hadn't been there before this. Here are pics of some of the birds we saw. (I didn't realize some of the settings on my camera were off, resulting in some over exposure, sorry!)
Belted Kingfisher (female):
A scaup parade led by an American Coot. I think that the 3rd scaup from the left is a greater scaup, the rest definitely are lesser scaup.
Little Blue Heron:
Lots of ducks: Coot, American Wigeon, two Gadwells.
(We also saw northern pintails, ruddy ducks, blue winged teal, northern shovelers and some mallards.)
Pied-billed grebe and horned grebe:
Blacknecked stilts, american avocets, northern pintails among others. The stilts and the avocets have successfully bred in the Slough the last few years.
Aside from the birds already mentioned, we also saw:
Orange crowned warbler
Yellow rumped warbleer
It was indeed birding heaven. If you are in San Diego, definitely worth a visit! See their website for more information.
