1976 Walter D. Koenig Melanerpes formicivorus BigTree Hastings Reservation (22 March) 1230. A bird (♂) was in the storage tree when I came to count: ✓ 378 (all in BigTree) 24 March 1130. What was apparently ♂108 (looked more like ♂y-Red/y-R) was sap-sucking in the tree along the fenceline. Within several minutes the other 2 birds were here also (♀104 and ♂110), all sap-sucking. 20 April 1400. 3 birds seen sitting in this area. 22 April 1440. 3 birds flushed from the BigTree sap tree (the one along the fence by Keep Out). Eventually all flew to this area, where I identified the 2 ♂'s (104 and 108) 28 April 1320. The 2 ♂'s seen and identified here. Holes checked. 30 April 1045. Something going on in the sap area up by the fence. See Keep Out notes. Most likely a dispute/1-2 intruders in this territory. 2 May 1330. Looked down and saw 4 (!) birds in the perch tree by the BigTree. At least 2 were ♂'s; one (the?) ♀ I looked at and couldn't get a good reading but from what I did see she appeared unbanded. Oh boy. A couple minutes later the ♀ returned followed by ♂108 2 adult ♂'s, the first of whom proceeded to mount the ♀ and the second of whom attacked the first when he arrived. One of the ♂'s was ♂ y-Red/y-led , who is still theoretically #108 (see 24 March above), but I'm not so sure any more. 1400. Well. As best as I can tell, the birds here are ① ♂104 → the mystery bird ② ♂108 → bands look y/y ③-④ 2 unringed ♀'s!
