1977 Walter D. Koenig Melanerpes formicivorus Pump (25 October) These birds are greeting one another, flying around, eating acorns, etc., just like they were a resident group (furthermore, most seem to be "unattached" birds, at least as far as I know). If only they'd start storing acorns here I'd feel more sure. 915. 2ub ♀♂ here now, both in the willow; 1-2 others as well. 917. 8 or 4el-2a#297 on storage limb in the Valley Oak. 922. The 2ub♀♂and 8297 greeting each other at the storage limb in the Valley Oak, then over in the willow. Possibly a 4th bird around also. Birds are flying to the Valley Dale over by the road to get acorns. 925. Somebody Carrickling in the willow thicket. 930. Actually, these birds seem to meet most any criterion for a "group" that I can think of. Certainly they are living here for now (and 8297 at least seems to be here regularly). They are clearly centered here and defending it from others. (Some intruders are here now getting chased). First they chased them from the trees by the pond, then they returned and grouped on the storage limb in the Valley Oak. 29 October 1425. At least 3 birds here, eating acorns in the Willow, among other things. 2ub and 2ub' seen. These birds may very well be storing in the remaining bark in the Willow. 1428. 3 birds (1♂, 2♀, I may be banded) together in Willow, flew over to greet (?) a 4th bird in the Valley Oak. 1435. Something upset one of the birds - (karrit-cutting). 1440. Leaving. Still really looks as though there are birds really living here. You might try to band some more here- 30 October 1345. Birds here again. Put the net up. 1500. Had caught a bird, but somehow he escaped from the net as I
