Long-Eared Owl

You can read the long and detailed report, or you can just read the relevent excerpt below:

Bill Haas' continuing quest for the Long-eared Owl has disclosed that mysterious species in 15 squares, most recently in Lawson Valley (R17). Extensive undisturbed oak woodland is the key habitat for the Long-eared Owl, revealed by Bill's searches to be far more widespread in San Diego County than anyone guessed before this project began. Phil Nelson saw the species at Tamarisk Grove (I24) on 17 and 18 March but since then they have deserted this traditional site.
