Cogswell 1948 Ereunetes mauri Oct. 31 - Bay Farm Id., Alameda, Alameda Co., Calif. (See entry under Enola algeira regarding foraging). Dec. 30 - Beach opposite S. end of Morris Bay, San Luis Obispo Co., Calif. - only 2 molivicolis in 1/2 hours walk up the beach, & there were fully 150 Least Sandpipers nearby — a reverse of the usual ratio of these two species on a sandy beach. 1949 Apr. 22 - base of St. Isabel to N. end of Golden Gate Fields racetrack, Contra Costa & Alameda Cos., Calif. Massed flocks, far outnumber all other shorebirds. Estimated 20,000 + near highway at high tide. Most are showing rusty on head, back; a few still rather gray. Apr. 23 - N.W end of Bay Farm Id., Alameda Co., Calif. — altho outnumbered by Dowithers along Oodittle Drive at ebb tide, this species is by far the most common on the broad flats NW of Island Rd. & Martland Drive now at noon (nearing low tides). I estimate 1 bird every 2 square yards of exposed mud — and they are so scattered all across to the dike along edge toward S.J. Bay proper. Some of the distant specks, of course, may be E. minutilla or E. algeira; but certainly most are this species. Only a few were seen in the up- turned tail threatening actions noted in spring. Some still show grayish cast to upperparts. [From map area of this region my est. of nos. here would be 374,400 !!! birds — perhaps too high]
