2 June 1000. Wandering around here, I ran across a blue oak just this side of the old A3 area (actually, between A3 and the Surrey Canyon Live Oak over here) that has 3 good-looking holes in it! The lowest, only about 10' off the ground and facing Keep Out (more or less) looked particularly fresh, and after watching a short time and seeing a bird go in I opened it, only to find 1 fresh egg! [marked 1: 25.7 x 19.0]. Huh.
7 June Apparently this is the 2nd nest; Neil saw two NOBA juns here.
13 June 1315. 4 eggs, incubated. ①+② 24.6 x 18.6 ③ 24.8 x 18.7 ④ 25.3 x 18.7. Set ambushes up all over the place.
20 June 1500. Checked the nest: 3 kids (1 a rent) + 1 unhatched eggs.
25 June 500. Ambushed the old nest hole (2 birds: 43833 and 43997) and the new hole above the current nest hole (4 birds: 43733, 43994, an adult ♂ NOBA [4186] and a juv fledgling [4187]. Good haul! Also, note that ♂4186 was not roosting in the nest, so there's almost certainly a 2nd NOBA ♂.
28 June 1630. Got the NOBA ♂ #2. Now only 1 (?) NOBA kid left here
1 July 800! Bummer - 2 kids dead in nest. Guess catching.
