Social Flycatcher, Myiozetetes similis, Photographed in the wild at the National Butterfly Center in Mission, TX.
The NBC is a wildlife refuge for native and migrating butterflies and birds. There are no cages, and winged critters are attracted by a wide range of host plants and feeders scattered around the gardens, fields and forest areas.
I took this photograph with a 50-200mm zoom which wasn’t quite long enough to give the DOF I wanted, so I blurred out the background in Photoshop to remove distractions. Olympus E-3, 158mm, 1/100 @ f/5.6, ISO 200
