Duval, E. H. 2000 Journal Isla Boca Brava, Chiriqui, Panama Apr un't its nestling, so I went back & picked up the egg. It was 29.1mm long x 21.1mm wide, & perfectly ellipsoidal. The contents more freely (ie no anchoring membrane?) Inside was an embryo, 8.4mm x 9.8mm with an eyespot ~ 1.5mm in diameter. There was no distinct yolk & the "white" of the egg was a milky pink color. I'm not sure why it failed or if it truly had. The abandoned egg from the nest near EDA, was broken & on the ground, with the (dead?) bodies of many small ants in it. On 11 April I found only a chick in nest E-7, which had been found on 10 April with one chick and one egg. I located the egg in the leaf litter below the nest and cracked it into a vial for storage in liquid N2. There was no embryo visible. The eggshell was folded into another vial and also frozen. As of 15 April, we've still been unable to identify the female associated with this nest.
