Dieta
Cuervillo de cañada/White-faced Ibis17-12-05 © Roberto Ares
The White-faced Ibis detects food using the tactile sensors on the bill. It introduces the bill in soft substrates such as mudflats or areas covered with grasses. A long and decurved bill facilitates the penetration into the substrate. It feeds on invertebrates, seeds, reptiles and amphibians.
