1976 Walter D. Koenig Melanerpes formicivorus Upper Arnold 2 (26 January) intruder was eventually driven off toward A3, leaving the ♀ alone once again. 1110. A ♂ was seen in the storage tree. After a [illegible] minutes he flew to the old nest Blue Oak toward A3 and proceeded to walk up it quite nervously; at this point ♂128 was seen in the storage tree. The ♂ split after reach a top snag. 1115. A ♂ now with the ♀ in the storage tree; he karrit-cuts loudly for ~2 minutes before being [illegible] threatened by the ♀, who flew up to the branch he was in with a threat posture.

Clearly her ties with A3 are still existent, as manifested by visits/intrusions by numerous
