1977 Walter D. Koenig Melanerpes formicivorus Hastings Reservation, Monterey Co., Calif. (18 March) sap and insects (I saw no foraging while I watched). This is really neat! See the back of p. 2 for a map. 19 March 1140. On my way up to School Hill from Red House I am greeted by an ub o' alongside the knoll just across the old road from Red House. He seemed to be alone. (See map on back). 22 March Noted 2 birds up Robertson Canyon in the same area where 323 was identified on 18 March. They were together in a Sycamore. [illegible] April Emplois the net at 7 am. 7 April 1100. While up at Lambert's, I could hear something big (revolution) going on nearby. I walked over to the scene, which was the old Dead Valley Dale just South of Lambert, which I will call "Near Lambert." Indeed, a revolution was in full progress, with 20+ birds involved, who were about 95% ♀ (I finally saw 1 ♂ after 10 minutes). None were banded. I set up a net, which was not placed very well, but did catch 2 ♀♀ (356 and 357) by 1200. 1215. A real-looking copulation took place: ♂ on ♀, low in the tree! Conditions being what they are, I'm going to take down the net and return with my camera. The ♂ is doing more than his share of chasing (a resident)
