  1. Provide artificial nesting sites for parrots

    A replicated study in 1992-2004 in a palm swamp in southeast Peru (Brightsmith & Bravo 2006) found that blue-and-yellow macaws Ara ararauna nested in modified Mauritia palms Mauritia flexuosa, but not in five PVC nest boxes (a pair of scarlet macaws A. macao used one box). A total of 41 palms had their crowns removed over the study period and slowly rotted to produce nesting cavities, with 12 nesting attempts by blue-and-yellow macaws in these cavities. Productivity in 1995 of two pairs of blue-and-yellow macaws and three pairs of red-bellied macaws Orthopsittaca manilata nesting in the palms was comparable to previous estimates for the region (50% success, 0.5 chicks/nest). As palms rotted and productivity declined over time, the authors recommend a rotation system to maintain both the structure of the palm swamp and provide adequate nesting cavities.
