1976 Walter D. Koenig Melanerpes formicivorus Road 1 Hastings Reservation (10 February) 1125. Several birds at each of the 2 x spots now. No wing-streamered birds seen. Birds are apparently sapsucking in a Live Oak in the bottom of the gulch here (+ on map). 1145. I moved down slightly to scare off the birds on the knoll that I could not see below me (⊙ on map). I could not tell what the birds had been doing; they were in a patch of young Blue Oaks and flushed first to a large Live Oak below (if I were forced to guess, I'd say they were probably sapsucking, but I could see very little resembling sap holes, and in any case, what would douglasii be doing with its sap running this time of year?) The birds, ☺ at least 4-5 of them, eventually flushed across the road and then all went up the ridge of Poison Oak Hill about 100 meters before stopping in a Live Oak there. In the group I saw all 4 of the early juveniles (180, 181, 182, 183); 181 had been definitely come from the area where I'd just flushed birds. I did not see any other wing-streamered birds: almost ½ way to first saddle ↓ Saddle PO Hill (×) Saprance of last year. 1200. Now I'm lower, and above me again several birds are greeting (about where the ☺ is). A chase occurs, then a minute later ♀ PRW is still in the tree where the chase occurred and then flies down rather than up to the other calling
