1981 Walter D. Koenig Melanerpes formicivorus Lower Haystack Hastings Reservation (6 April) 1130. Caught 9509 in the net as she was flying & into the MT. Measured and released her. 1140. As a Cooper's Hawk came cruising by being chased by the Kestrel, at least 2-3 birds gave alarm calls, while everyone shut up and hid. Why, if alarm calling is neotism, should birds at Revolutions give them? To warn their direct competitors? 1145. Well, at the moment I'd still hesitate to call this one. The 2 ub 99 are clearly ahead in that they are in charge of the MT, but the real power still to be dealt with there is 9587. Meanwhile, 9642's advantage may actually be that she need not contend (at least at the moment) with 9587. Even though 9642 is off on the periphery, she appears to be the only bird that the 88 are fairly chummy with (other than 9587); I would thus still have to refrain from counting her out. Other contenders are several and there is still a lot of chasing going on, so things are definitely not over here yet. 1154. More good news: at least 1 ub 9 in the MT is now being chased by both of the 88! Meanwhile, 8461 (at least) is still going over to 9642 in the 2nd Tree every so often and is still quite friendly with her. The 88 really are now (all of a sudden?) doing a lot of chasing of 1 or more 99 in the MT. However, 9587 is definitely not one of those being chased. 1230. Counted stores: 1342. Leaving. Still lots going on here.
