The turquoise-winged parrotlet (Forpus spengeli ) is a species of parrot in the family Pscittacidae.
Turquoise-winged parrotlets are typically 12 centimetres (4.7 in) long and weigh about 28 grams (0.99 oz). Their bodies are mostly yellow-green; eyes are dark brown and legs and beak are light peach. Turquoise-winged parrotlets are sexually dimorphic: males have bright turquoise feathers on their lower backs and rumps, and have purple-blue underwing coverts and axillaries. Females have no blue markings, but their foreheads and faces are brighter yellow-green than males'. Like all parrots, turquoise-winged parrotlets exhibit zygodactyly: two toes face forward and two toes face backward.
Turquoise-winged parrotlets are found in northern Colombia from the Caribbean coastal region southwest of the Santa Marta Mountains, Atlantico, and south along the Rio Magdalena in Bolívar and Cesar.
Turquoise-winged parrotlets are most often found in drier, open or riparian woodlands, cerrado, caatinga, savanna, palm groves, semi-arid scrubland, and pastures.
Turquoise-winged parrotlets mostly feed on Cecropia sp. fruits, Mikania sp. and Trema micrantha seeds, and Ambrosia sp. and Marcgravia sp. flowers. They are also known to occasionally feed on other plants such as grass.
The turquoise-winged parrotlet's breeding season is May to August. Females lay 3-7 small white eggs.
There is not an estimate for the number of turquoise-winged parrotlets, but it is believed that their population is decreasing because of increased human interference and habitat destruction. Turquoise-winged parrotlets are listed as Least Concern by the IUCN Red List.
