Inca Tern

Larosterna Inca

Inca Terns are best known for their white “mustaches,” found on both male and female birds. Unfortunately, Inca Tern numbers are decreasing in South America, largely as a result of declining fish populations. Nesting on rocky cliffs in the wild, the El Paso Zoo’s Inca Terns show the same behavior in the rock work upon entering the Aviary.
