1976 Walter D. Koerig 4 Melanerpes formicivorus BigTree Hastings Reservation 9 May 1215. All 4 birds here; only one [illegible] identified (but a 2nd ♀ was present). Birds mostly hawking but some bark gleaning seems to be going on. Several flights made to the storage tree, but not apparently to a known hole. 10 May 2015. Birds are roosting in Valley Oak immediately next to the road across from the perch tree. All 4 were seen. 11 May 1700. I set up for an ambush here. It occurs to me in walking by here and flushing the group, however, how "pack-like" they are acting - not all being in one place, necessarily, but all flying together at the same moment and landing at the same place within inches of each other. This is very reminiscent of the similar behavior seen in a magnified form at A3 and BlackOak just before they began nesting, and I suspect that there's a good chance that the same phenomenon may be about to occur here. 12 May The ambush was ½ successful - somehow 2 of the birds (♂108 and one of the ♀♀) managed to get around (through?) - the wire net. In any case I did catch ♂104 and an unringed ♀, apparently a first-year bird (pointed 1°, very worn retrices) rectrices) who was #399 and is now #264. I also counted stores here: 📋 120 (definitely getting to the bottom). 20 May 1805. Walked over here, flushing 2 birds from one of the holes in the Valley Oak roost tree east of BigTree. One other bird was seen for a total of 3. 24 May 1520. Both ♂♂ (104, 108) sitting in perch tree. Holes checked; ♀ not seen. / Flash! ♀ found in hole in rear storage tree. That's it!
