The nocturnal spectacled owl (Pulsatrix perspicillata), characterised by spectacles made of white feathers around its eyes and throat, is the largest tropical owl species. The male call sounds like a hammer hitting a hollow tree that gets progressively quieter. Females have a screech call that is mainly used to attract males during the breeding season. The majority of the spectacled owl diet is made up of mice and insects. They are fast hunters swooping down onto prey before quickly returning to their perch. Insects are plucked directly off vegetation. The spectacled owl lives in thick, tropical rainforests, wetlands and savannahs, from Mexico to South America.
