45 Journal Borell 1964 Ojo Sahuero, Chihuahua, 5200 ft. May Simmon - Apr 21 - May 20 Continued. American Redstart - 3 Black-throated Gray Warbler - 1 Audubon Warbler, Common from Apr 21 here and at Flores Mayor, last recorded or may 18 Black and white warbler - 2 Townsend Warbler, 1 to 3 each day from May 2 through at least May 12. Meadowlark, common in all grassy areas. Now all in pairs. Their song indicates that all the nesting birds that I have encountered are Eastern. Red-winged blackbird, like the myriator Flocco left in early may redwings are not common. I know of only 3 singing &o. Of course the marsh situation is not good this year.
