Finally do OK here. ♂624 Blue-Red / Blue-Red, ♂545 tBlue / Metal ♀652 Yellow / Corn all seen in the Lambert area. ♂691 pBlue-Yellow (N) / Corn and ♂624 were seen in the keep out area earlier, about 1030. 1200, ♂691 finally seen in the Lambert area, so a complete census up here. But... A 5th bird is around, whose left leg bands I read as ♂ B Pink / Metal, absolutely unresolvable with any other Black Oak birds. Could it be the old Lambert ♂[illegible]583? Will have to check. Seems friendly (or at least not aggressive) with the other birds, although I have seen some chases up here. Will I ever figure out what's going on up here? Sample of 50 acorns taken from the down limb, + replaced with an equivalent number.
