The white ibis has several other distinctive features. It has a pink coloration on its face that is bare skin rather than feathers where the beak meets the face. In flight, it reveals black tips on its wings, which are hidden when walking. Its neck is also straight in flight.
White ibises are most commonly found in Costa Rica in the wetlands around he Gulf of Nicoya, which is exactly where I took this photograph. The Tempisque River in Palo Verde National Park flows into the Gulf of Nicoya, which divides the Nicoya Peninsula from the area of Costa Rica nearer to San Jose.
White ibis reach lengths of 63 cm (25 in), so they are smaller than many herons or egrets. Their scientific name is eudocimus albus. Not surprisingly, they are known locally in Costa Rica as ibis blanco.
