(131) Thus Brown-eyes, on this occasion, after eating all she wanted, proceeded to search the grass and surrounding plants for more food almost frantically. I have not observed such activity before and it gives rise immediately to the thought, that, perhaps; perhaps, there are young in the nest and the food problem is now urgent. I have never looked in this nest, so do not know what it contains, but, off hand it would seems that young are at about due. At 9;15 a thrasher was singing beautifully in the canyon below and west of the house. I went down to the fence along my western line to a point, as determined from the map, 110 yards from the nest NO.3 as the crow flies. The song came from the canyon below and, I estimated the location of the singer at about 100 yards further west and about 50 feet lower in elevatio (I have contour maps of this section). The intervening hill- side slopes steeply and is densely covered with scrub live oak, baccharis ("Coyote bush"-"Chaparral broom"), mimulus, etc. It is impossible to see through it. I called when the song ceased and presently a thrasher began calling: "Scrap, scrap." The sound gradually approached and once I caught a glimpse of a thrasher momentarily on a branch of an oak about 60 yards away. From that point the call was much louder. I was, myself standing in a thicket of oak and hazel. I continued calling and the bird answering and rapidly approaching, apparently on the ground. From its call I thought it to be Green-eyes, but when the bird walked out of the thicket about six feet from me, crawled through the fence and jumped up into my hand, it was Brown-eyes. The bird certainly could not see me when I began calling; she had never seen me, as far as I know, in these surroundings. I had never seen her anywhere near this place and neither of us from past experience had any reason to expect to see the other
