26. Birth to a colt (yng was about 3 out.) Black-b. Magpie - Helped Rowans Bond 3 yng from nest I found yesterday @ Mi. W. Murphy's. Nest was 4' up in dense willows. There were also 4 infertile eggs. West. Kingbird - Looked at nest (found yesterday) just before leaving the morning Camp. Found no eggs. Some new material had been added since yesterday, including wads of cotton (probably from debris left from skinning) Say Chorus - Banded 5 yng from nest under pool at Murphy's. Parent close to nest most of the time. Citellus laredon - We spent time looking for these between morning Camp & Murphy's. Only a few old mounds were seen. From my observations today it seems that the species is located in just a few isolated colonies. Appears that they were more abundant and then now due to our finding many old and unused mounds. (Perhaps they migrate?) "Old timers" at Murphy's say they used to be there by the millions & that a disease took toll several yrs. ago. (They call them Sage Squirrels) Our biggest study of these today was in a sharply circumscribed area (Giffords) of about a square 4 mi.
