Barbs 1960 Zonotrichia leucophrys 9. June 22 2½ mi S, 5¼ mi E Detroit, 2000 ft., Marion Co. Oregon The White-crests here seem to be all on the slope or on the top just at the edge of the slope. The slope is S- facing, so is sunny all day. Here the ground cover seems densest, there being fewer open spaces due to the logging operations. Chipping sparrows are abundant here, juncos less so. There are several hawks (4 at least). As I write this, all is very quiet, so far as Zonotrichia goes. June 23 Tooh a pair which fell in almost the same place. One 840-941 had had insects (?) in its bill. Late, got one of a 842. pair which I chased for a long time, yesterday & today. This appears to be all I can get from this population. I've taken 10, and would estimate the original population to be not over ten pairs, perhaps not that many.
