1983 R.C. Numme Melanerpes formicivorus Bianca 17Jan ** GROUP UPDATE ** ① 9871 (9NB) died of unnatural cause 04Oct1982 ② Juvs. 764,765,766 NSA B 29 May 1982 ③ J.763 disappeared 23 July 1982 ± 2 weeks Lastseen 27 June, gone by 18 Aug 4 Jun Watching here 1230, after Walter reported the collapse of the main Black Oak granary tree. However, I still can find ~100 acorns stored in a dead limb of a Valley Oak 40m down the ridge, near the very tall, spindly Valley Oak. 1305, success. A 9NB and a 8NB definitely still here. First picked them up on the border of the woods between Bianca & Black Oak. Saw the 8NB fly to the knoll VO, then the 9 fly to the granary very purposefully to chase a Plain Titmouse. She was joined there by the 8NB. 16May Nobody in any holes, though birds + acorns appear to be present 23May Nobody in any holes 1430 4 Jun Nobody in any holes 24 June Watching 0740, 0900 OK. One 8 + one 9, both fairly surely (but not positively) unbandeD. No sign of a nest, though I did see the 8 holding an entire acorn for a few moments. I guess they still have a few acorns left. 9 Oct 1045, karrits + a good number of stored acorns (Golden Oak + Black Oak) indicate that Bianca is occupied.
