Salton Sea & Imperial Valley
4 Sep 2006
by Henry Detwiler

Mickey and I braved the 109-degree heat & humidity to hunt down some fine Imperial Valley birds.

We left Yuma at 5:30am and started our birding in the Imperial Valley just as the sun peeked over the horizon.  A flooded field of Bermuda Grass highlighted why so many birders make the pilmigrage to the Salton Sea area.  It was teeming with 100's of White-faced Ibis, egrets, Willets, Black-necked Stilts, yellowlegs, dowitchers, Wilson's Phalaropes, and other birds.

Black-necked Stilt & Wilson's Phalarope

At Finney Lake we found both Western and Clark's Grebes, and found almost all the small dead snags emerging from the water covered with swallows--mostly Tree, but a sprinkling of Bank and Cliff Swallows, too.

Our first stop at the Salton Sea itself was Obsidian Butte.  The east side of this peninsula was as birdy as I've ever seen it, with terns, pelicans, gulls, and cormorants.

Yellow-footed Gull

Here we found Mickey's life Yellow-footed Gull--lots of them, in fact.  The Yellow-footed Gulls rear their young in the Gulf of California, and then fly up to the Salton Sea for a post-breeding vacation.  During the late summer you can find hundreds here--but come the winter there are only a few left on the entire sea.  While the east side of Obsidian Butte was great, the west side was fantastic!  Hundreds each of Caspian Terns, Black Skimmers, and Brown Pelicans shared the islands and surrounding waters with other terns, gulls, and shorebirds.

When startled, the Black Skimmers and Caspian Terns would lift off the islands and wheel around a couple of times before landing again, rearranging themselves in the viewing arena.


Caspian Terns



Black, Forster's, & Common Terns
and Brown Pelicans, of course!

This turned out to be an excellent spot to examine an assortment of terns in a variety of plumages:  Black, Forster's, and Common.  Offshore from here there had been several sightings of jaegers earlier in the day--but we missed them.

Following the sea wall to the south, we came upon this falcon surveying the shoreline for lunch.  It stayed put long enough for me to take this digiscoped shot with my Sony DSC W7, hand-held up to the eyepiece of my Swarovski 65mm spotting scope.  A nearby field held several hundred Laughing and Bonaparte's Gulls.

The irrigated fields in the Imperial Valley are not all alike by any means.  Many have their own unique species, depending on the height of the water, type of crop, and available food sources.  A couple of fields seemed to attract good numbers of Black Terns, while others had none.  Similarly, we found a flock of Black-bellied Plovers in one field, and saw them nowhere else.
   


Ruff, Imperial Valley

In a field close to Hoober Road & Hwy 115, we met Guy McCaskie and Gjon Hazard.  They pointed out some Baird's Sandpipers, and then we moved together to another flock of shorebirds in a different part of the field.  Here I found this colorful Ruff, which was our rarest bird of the day.  After looking over a few more watery fields, Mickey and I called it quits--driven out by the heat and humidity.  But it had been an amazing day, filled with the spectacle of 1000s of beautiful birds!
