Provide artificial nesting sites for parrots
A replicated study in 2004-6 in four tropical montane sites in Colombia (Quevedo et al. 2006) found that four of five threatened parrot species bred and roosted in 240 nest boxes provided. Indigo-winged parrots Hapalopsittaca fuertesi, golden-plumed parakeets Leptosittaca branickii, flame-winged parakeets Pyrhura calliptera and Santa Marta parakeets P. viridicata all used the nest boxes, with an increase in the numbers of young individuals of indigo-winged parrots and golden-plumed parakeets entering natural populations. There was no evidence that rusty-faced parrots H. amazonina used boxes. Boxes were 100 x 25 x 25 cm with a 10-15 cm entrance hole, except for those designed for rusty-faced parrots, which were only 60 cm tall. All boxes had grooves to allow parrots to climb the inside.
