White-faced Ibis

Erika and I added the White-faced Ibis to our February trip list at the Estero Llano Grande State Park in south Texas. I have previously posted a note on how to differentiate between White-faced and Glossy ibis. The White-faced Ibis is the more likely species in most of Texas. The species breeds in the western United States and winters in Mexico, western Louisiana, and eastern Texas. Also note the red facial skin on this ibis. This area is dark or blue in Glossy Ibis.

The two ibis have interbred in captivity, but are not known to do so in the wild. Thus, for the time being anyway, they are considered to be distinct species (Ryder and Manry 1994).
