Ambushed the lower Blue Oak hole tonight with Morne and Roger, catching the 2 1st yr birds (81899 81900) along with the ♀NOBA, now 81903. Maybe we'll eventually be able to figure out what went on here last summer? 5 April 900. Watching, with the thought, at least, of doing a mate-guarding watch. There egg acorns remaining here. 925. ♀(m)/m #8899 flew in. Now 288! 933. A ♂ flew to a new hole in one of the upper Valley Oaks! This is no doubt The one we missed last year! Now 2 girls up there! Birds going in & out of the hole. 945. Well, I think this does in the mate-guarding. Better go check the hole instead! 1115. Well! I went up and opened the hole from below, finding it empty and still being built. But it was also very rotten and very hard to put back together, so I moved up and started to open a hole on top of the limb, only to have the whole limb collapse and fall off! Oops! So much for that hole. At least it won't collapse when they have babies! 25 April 1130. After Mark reported 4 incubated eggs in the upper hole of the 4th enclosure tree I went up and placed 2 cardboard.
