21 April
1800. Bird flushed from 1988 (2nd) nest hole. Climbed up and
checked it - it has been deepened and I couldn't reach the
bottom, but with a stick I was pretty sure I felt at least
2 eggs.
22 April
1700. Opened the hole, which has 3 eggs; 2 are opaque and
dirty, one translucent and dirty. My guess is that only the
2 are fertile and that incubation is well along.
27 April
1420. Noone in hole, but still 3 eggs, warm & dirty.
30 April
1200. All 3 babies have hatched; look fine!
13 May
1140. Set up for nest ambush.
1300. NOBA ♀ came to feed! Got her! Banded and released by 1315.
Staying on to try for a 2nd bird. ♀ is now #1687.
1400. Pretty darn slow up here. Will have to try again tomorrow.
14 May
1445. Set up and trying again.
1545. 08 or M #530, fed.
1625. 8 or Wh/m #530 again.
1645. Leaving. My guess is that it's just a pair here: 8530
and the new ♀ that I caught yesterday. Things are so
slow here that's it's hard to know for sure, but I doubt
anyone else is here. Indeed, were all those other birds
(♀1374, ♀1389, & 8ub) really seen well earlier this year?
Sorry, Mark - it was too cold, and I was too tired, to measure
the babies!
21 May
1515. Came up to band the babies only to find them (2) dead and
cold in the nest. What happened? Babies have certainly not
been dead more than a day or so. WL = 59 and 55. Parasites
are still on them! I guess I'll take them back and get tissue.
