White-faced Ibis breed in marshes, usually nesting in bushes or low trees.  Locally common, the White-faced Ibis winters in large flocks in Mexico, western Louisiana, and Eastern Texas.

This species has been reported as being sensitive to pesticide contamination and eggshell thinning has been detected in Texas colonies and this may be attributed to their nesting near agricultural drainage canals.
