hh Wolf 1964 Journal August 10 Cuernavaca, Morelos Mexico Up at 0500 after bed nights sleep. After breakfast drove out to 5 mi. E. Cuernavaca where Dick left me to watch Rusty Sparrows while he drove back up to the pine-oak locality 7.5 mi. N. of town. I spent until 12:15 watching Rusty Sparrows. Concentrated on pairs 1,4,2,&6. Apparently the pair I watched yesterday that had a young out of the nest is pair 6 which moved to SE after I first watched them. Probably due to limited wanderings of the young. Checked the Blue Grosbeak & Brown Towhee nests. Grosbeak had laid another egg & a Bronzed Cowbird had contributed one. Also found another Violet-crowned Hummingbird building a nest. This makes three nests - one with 2 eggs & two being built. I have found no young birds so the hummers are apparently just beginning to breed - maybe for 2nd time this year?? Saw first Tanager species for the area. Moved to a mistlobe champ while Dicks following it. Clear all morning until 1000 & then began to cloud over on ridges to N & moved south. Back to town where prepared specimens while Dick took car in to have it fixed & went to market. Had supper, wrote notes, & to bed at 2030.
