18 June Walter reports legg yesterday by ♀604, and no eggs
today. See his notes for details.
→ **Also, further insights into the death of ♂173
and failure of the first nest, Leslie's nest watch of
30 May would suggest that the nest had failed by
that time already. Only a few visits to the nest by
♀604 + ♂173, without ever going in, excepting 1 visit
by ♂173, However, ♂S62 also visited the nest
once and peeped in, but did not enter, and ♂173
was very much alive at this date! Very interesting.
All kinds of possibilities. Infanticide, murder,
etc. impossible to tell, but at least we can
eliminate all the scenarios of ♂173 dying as the nest
failing all at the same time. Also, we must now
consider scenarios of ♂S61 + ♂S62 actively contributing
to the demise of both. Very interesting.
** GROUP UPDATE **
① ♂173 found dead, died ~ 5 June
② ♂S61 + ♂S62 moved here ~ 7 June (± 1 week,
but not plus. These 2 ♂♂ were here for sure on
9 June (See Leslie's notes). See above discussion
for further info.
28 June Leslie reported weirdness here yesterday: No incubation during
a nest watch, but lots of flying around by the four residents,
wasas, & intruders. I walk up here at 0930 and find
things relatively calm. And it looks like incubation is
still in progress. I do a 2 hour nest watch
