Melantrypes formicivorus
Low Hay
21 April Watching here 0610: Well well, at 0615 hanging out in
the starling nest tree in the 2° area are both a ♀N13
(certain) and a ♂N13 (pretty sure). Perched only 30
meters away near the Blue Oak nest tree are 3 Low Hay residents.
Ever heard the two newcomers wake to each other!
0645, Un-oh, ♂523 is looking out of the 79 hole!
Probably entered about 0630, when she flew to the quarry
from the 2° area, not followed by ♂461. I bet she has
laid! Timing seemed right, etc. ♂523 leaves 0655.
Whoa, 0707 ♂524 enters nest, leaves <10sec
later carrying egg! Almost certainly just laid by ♂523.
The egg was carried by ♂524 to a high, uphill branch
of the tree, and she pecked at it a few times before
ticking up higher. The egg looked pretty small.
Could have been a runt! I might be able to get to
it to measure it before its destroyed, but I better
give ♂524 a chance to lay, first.
0715 ♂524 enters, 1.0. 30sec later, leaves 0716:
0727, (checking nest. Empty (thank god!)
Plus, I was able to get to the egg placed in the tree,
NOT A RUNT! 25.5 x 20.3, with (as is the
norm for ♂523) an asymmetrical air cell. We're in good
shape!
The egg had a very small pustule near the middle of the egg.
0755, En blind, watching hole egg. I don't believe ♂524
was going to lay today, as she made two short trips to the
hole Notes on egg eating on back End 0845.
