Thryothorus ludovicianus, Carolina Wren, collected outside of lab

Detailed Description

Carolina Wren - Thryothorus ludovicianus. A common co-inhabitant with human nests. In this case a Wren made a nest in a tub of rags we had outside under a shed roof. We watched it for a while, but then found the tub also had a Black Rat Snake and the nest was mysteriously abandoned. We took a picture of the left over egg....lovely in its speckles laid down in the birds oviduct. Kelly Graninger took the shot. Photography Information: Canon Mark II 5D, Zerene Stacker, Stackshot Sled, 65mm Canon MP-E 1-5X macro lens, Twin Macro Flash in Styrofoam Cooler, F5.0, ISO 100, Shutter Speed 200 USGSBIML Photoshopping Technique: Note that we now have added using the burn tool at 50% opacity set to shadows to clean up the halos that bleed into the black background from "hot" color sections of the picture.
