1976 Walter D. Koening Melanerpes formicivorus Road 1 Hastings Reservation (16 April) 1715. Walked down to nest tree; a bird flushed from the late '75 nest hole. I therefore immediately walked back, retrieved the ladder, returned at 1800, and opened the hole; no eggs were inside. It does seem like the likely site for the nest this year, however. 17 April 1200. No eggs in the hole yet. 18 April 1700. Nothing in hole. 1900. Birds roosting in the above hole and the old nest hole on the other side cut open by Michael. 20 April 900. Lots of birds in storage area when I came to check holes. I didn't find any woodpeckers in them but there was a Starling (!) in the early '75 nest hole who will have to be dealt with. 905. As it happens, the activity is again being caused by the persistent presence of several intruders here, putting the circumstance into the standard frenzy, complete with all symptoms. The only difference is that in this case the resident birds far outnumber the intruders by an estimated 8:2; and thus have the situation relatively well in hand, as someone is just about anywhere in the territory at any one time and as a result the intruders never get to stop anywhere for more than a few seconds, and certainly do not make it to the storage tree. I watched to 945, seeing 8 residents: (1) RRL #249, (2) Pub, (3) #669, and 5 1st year birds - #180, #181, #182, #183, #222. One intruder was unmarked, unwilling streamer, a second was OrRW w/DBlue Bar, neither was sexed. This makes him #246 from Haystack-Blouquit, no less.
