The squirrel cuckoo, also known as Piaya cayana, is a type of cuckoo that is both big and lively. It has an exceptionally long tail, measuring anywhere from 40.5 to 50 centimeters (15.9 to 19.7 inches) and weighs between 95 to 120 grams (3.4 to 4.2 ounces).
Grown-up birds possess chestnut upper parts and head which gradually transform into a gentle pink hue around the throat area. The gray lower breast and nearly black belly are accompanied by rufous central tail feathers, while the outer ones have white tips. Additionally, the bill appears yellow and the eyes are red. These avian creatures are commonly found from Northwestern Mexico down to Northern Argentina, Uruguay and Trinidad.
