The Avra Valley sewage treatment plant, approximately 10 miles west of Tucson, Arizona, has four large and several small ponds that are, depending on their water levels, often attractive to shorebirds. The large pond immediately west of the office building is being drawn down, and should provide good habitat for at least the next several days. Two and a half hours of watching there this morning produced the following:
Least Sandpiper, 39 ad, 3 juv
Baird's Sandpiper, 11 ad
Western Sandpiper, 5 ad, 3 juv
Lesser Yellowlegs, 1 ad, 2 juv
Willet, 1 ad
Long-billed Dowitcher, 8 ad
Wilson's Phalarope, ca. 30, including juvs
Semipalmated Plover, 1 ad
Killdeer, ca. 10
Black-necked Stilt, 125
