Creco - July 1929 Squirt allowed me to approach within five feet of it when and only an adult (?) 15ft away gave a sharp alarm note and the youngster dropped into its hole. The adult assumed the picket-pin attitude and sniffed and watched me while the youngster almost immediately put its head out of its hole again - chipmunks were seen and many golden-mantled ground squirrels. Much blasting on new highway. List of birds seen (or heard) at Creco July 11-15. Sierra Brown .
