Origin Nandayus nenday is native to Neotropical South America. A popular pet bird, black-hooded parakeets were introduced to the United States by escaping enclosures or intentional releases. Life Cycle N. nenday are approximately 12 in. (30 cm) in length and weigh 5 oz (140 g). Plumage is bluish-green on the chest with black feathers on the head and a black beak. Feathers on the thighs are red. Females are smaller than males with a more curved beak. N. nenday gather in large communal roosts outside of breeding season. During nesting season, females lay 3-5 eggs in a clutch with nests found in holes in trees. Distribution N. nenday have established large breeding populations in California, Texas, and Florida. Control Efforts Large populations of N. nenday could pose a threat to crops. However, limited problems have been reported. https://www.parrots.org/encyclopedia/nanday-conure
