1982 R.C. Munne 4 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.
