Feb 2. notes and the ♂ flew into that oak, onto the trunk nearby. He then moved up in to the tree and I couldn't tell that anything went on there. I found a broken off branch, healed over but with no real cavity. About 8:35, I located another pair moving N from a point SE of the house. The birds went into a large liveoak NE of house and W of windmill. Again one bird was talkative and the other foraged more steadily. I noted some attention to oak leaves on the part of the latter. The birds then flew to liveoak on W side of house and the ♂, calling vet-vet-vet, circled N and E to liveoak W of tank. I had lost track of ♀ meanwhile but saw her in liveoak, foraging. A third ♂ was present and mild "approach-threat" was directed toward presumed first "♂" in tree (one with mate, there earlier). No real struggle nor exchange of song. Two birds flew to SE, followed by a third, all going to liveoak SE of house. Then 2 birds together, after foraging briefly in live oak (twig in one case), moved quickly thru brush to next liveoak to S. I left them there at 8:55 with an impression that liveoaks may be of considerable importance for foraging although they are only scattered or concentrated along streamcourses here. The foraging observations thus recorded may
