Anyone who has traveled west on I-8 to San Diego has passed through the Paloma Ranch, which encompasses much of the Citrus Valley just west of Gila Bend.  It's an oasis in the desert, and along its western boundary is a heron and cormorant rookery.  During the summer of 2001 all three species of egrets, cormorants, and Black-crowned Night Herons bred. 
  
In late May there was a "plague" of tarantula hawks, which were feasting on the mesquite flowers.

Double-crested Cormorant

Aside from egrets and herons, many other birds take advantage of the cover and the water.  Cliff Swallows come from the nearby overpass, grackles often roost in the trees, and last year a pair of Greater Roadrunners bred in the mesquite.

Egret Rookery in the mesquite

     
Since this rookery is on the way to and from Luke Air Force Base, I often stop there on the way to my Reserves duty.  Last summer there were numerous bees and butterflies taking advantage of the weeds and flowers.
    

   
    


Immature Great Egrets

This photo was taken through the vegetation, giving a filtered effect.  The sharpest photos on this page were made using my digital camera and scope.  The pictures of the grackles, egrets, and the d-c cormorant were taken with a Canon zoom lens and then scanned from slides, yielding much less resolution.


Because of the extraordinary bird life, I was able to experiment with my digital photography here, and figured out some tricks that yield consistently recognizable photos (provided there is enough light).

The photo of the adult Black-crowned night heron on the right was taken at a shutter speed of 1/500 of a second to cut down on vibration.

The photo of the Snowy Egret was taken with my Canon camera, panning as the bird flew by.

Wilson's Warblers can be thick during spring & fall migration.  And finally, here's a closing shot--not too difficult to ID this bird!
