5 June Checked the hole, 1730: 7 eggs stone cold!
Has the nest been abandoned? It was active
Friday when we did a snake experiment here.
Anyway, the 7 eggs measure out
① 25.3 x 18.9 (496)
② 26.3 x 20.1 (494)
③ 26.0 x 19.1 (496) ?
④ 27.0 x 20.2 (494)
⑤ 26.2 x 19.9 (494)
⑥ 26.4 x 19.2 (496)
⑦ 26.2 x 19.7 (494) laid 28 May
I suspect that the snake experiment may have
directly caused abandonment. Also, the birds have been
making a lot of [illegible] noise here. I wonder if
♂521 has disappeared.
15 June Routine gravity census (back):
17 June " " " All 5 birds (♂521, ♀494,
♀496, ♂721, ♂723) see well
1 July Wow, strange goings-on here. Around 1200, while walking
down from Buckeye, up in the vicinity of the 81
nest tree, I find ♂521 sitting next to a banded
juvenile! In the late PM (~1800) I watch ad
find J889 of Pipeline M / white Green! Amazing!
This juvenile wandered a full mile up the canyon
and wound up on the territory with his grandparents!
