1979 Walter D. Koenig Melanerpes formicivorus School Hill Hastings Reservation (21 April) 935. Scratch that. A ♂ is in the tree above the exclosure and is ♂ Yel/Red #402. He is hawking and gives occasional Garricks. 950. #402 flew down to lower area. No obvious chasing has occurred and his Garricks were not acted upon. Hmm. Is he returning here? If so, why does he Garrick and act like an intruder? What's his status with the other 2 birds (886, remember, is presumably his father or uncle). 1000. Now leaving. This ♂ is pretty interesting. Might be worth watching roosting to see if 2 (?) birds are roosting here. 1003. Several questions solved: All 3 of these birds - ♂, ♀, and ♂ Yel/DP #402, are peacefully coexisting in a Valley Oak down below the exclosure eating catkins. It would appear as though #402 is rejoining this group as well. Both interesting! No aggression resulted from this, though each was several feet away from the others. 24 April 1750. Noone in any holes. 29 April Add: ♀260. Moved as adult 3 April (see notes) 3 May 1130. Checked '77 (etc.) nest hole - bottom ok but no eggs (Larry reported a bird in here last week). 7 May 1905. Late this evening I came up and shouted at the '77 hole to no avail. But I did scare a bird from the storage area, who flew up to the top of the exclosure and then, after several minutes, returned and roosted in the hole (alone, as best I could tell).
