12 April
1045. No stores left, best I can tell.
Pretty quiet up here.
25 April
1220. Doug had reported a bird in the 2001 hole, so
I checked it: in good shape but empty.
8 May
1205. Opened last year's hole again; still empty.
22 May
1030. And it's still empty.
17 August
Presumably was a group here this spring
(Joey saw 3 birds on 16 July) but we've failed
at getting much of a fix on them since early
spring. No nest and no stores, at the most!
2003
19 April
1130. Bird in hole (tag 1315): 1 fresh egg, marked
(25.7 x 21.1). Stores here: yes.
21 April
1310. Check hole: still the 1 egg (!)
26 April
1225. Still the 1 egg - and it's developed! They're
apparently incubating it! Wow. A real 1-egg clutch!
10 May
945. Hole empty. Yet another weather casualty,
I dare say, directly or indirectly.
20 May
1215 Bird in (same) hole: Legg, not so fresh that
I'd swear they're going to lay more. Size: 25.4 x 22.0
(as close to a ball as any I've seen!) Another
1 egg clutch!
30 May
915. 1 baby, ~2-3 do. Band ~ 17 June.
Ambusher set as in case there are NOBAs.
10 June
1600. Hole empty! There are definitely still
stores here, by the way.
18 June
1630. Bird in new hole, in lobata or Bradley's
