5 June 0550-0640 Spied, hello'd - got nothing. Several (Flights into gran, several to road (or beyond). ???
6 June 0945-1000 Spied From truck. A bird went to tool hole!
1030 Climbed. Empty, but I dumped in .5 l of chips. ->
8 June Erected a platform - worked like a charm! No food
To make a platform you must have L-shaped metal fence posts (not the T-shaped ones). See diagram on back. Use self-tapping screws. Go through the holes in the metal post.
10 June Jim Yooked for nest yesterday - nothing. I spent From 0610-0635 spying. 2 Flights to creek (cliff places), some flights down from uphill. But what really makes me wonder was the garricking (just once) and drumming (twice). Is this a finch effect. Census!
4 Aug 1400 Val reported a bird in the hole last nite at 2000. I watched it for 10 min r saw nothing. Hello'd-nada. Put Food on platform. Set ambush at dusk - 4 in!
5 Aug 0400 Ambush! But 1 (BM) escapes while I'm pulling birds out. Damn! I do a cort series as well, but I later Find out several got spun out in the centrifuge. Plus Val pooled all but 1 tube before the spin (wrong!). So all that work is completely Fucked. Took birds in For lapping. 1609 (BM) has overy coming into conduit. HM 2015 semi- wormy parasite small testes but hey, it's too early to really tell or is it normal for HM for a successful ambush, it certainly did suck. Christ! This was the only potential Fall nest with a & helper.
