1976 Walter D. Koenig Melanerpes formicivorus 10 MacRoberts Hastings Reservation (9 November) and was greeted with a full opened-winged walk by the subordinate ♂. Seconds later the other ♂ flew up as well and proceeded to pick up where he left off. The subordinate bird did not leave, however. Perhaps this is how such an entry into a group can be achieved - a ♂, for example, may under some circumstances be accepted if he fully and clearly understands that he is a subordinate 1600. Leaving, to return at dusk. At dusk only 2 birds were present, a ♂ and ♀. The ♀ disappeared rather early, leaving the ♂ on the granary, where he mostly flew hawked (probably for the oak moths). At roost time he headed over my head directly toward Chongo gulch, where I lost him. This is probably the same hole where they were seen going by us in September. But wow - when I lost him he was near the path leading around the hill that I take toward Chongo. This may be a first - birds roosting somewhere entirely off their territory. (An alternative explanation, perhaps, is that he is budding from Chongo (or Buckeye?) and still returning there to roost. 16 November 930. Sub hawkling from granary. I'm going to set up a net. 1000. Net up. 2 birds came briefly while I was setting it. 1015. Sub in granary working stores. Flew to tree on left along fence. 1025. Flurry of karrit-cuts and a chase - certainly an intruder - who is ♂-w-? /m #194 from 1500 (formerly School Hill). 1030. Leaving. Net still up. 1240. No catch. Captive AW in cage in tree now. 1245. ♂ sub came almost immediately. Very interested in
