  1. Provide artificial nesting sites for parrots

    A replicated study in 1993-9 in a tropical forest on an island in Venezuela (Sanz et al. 2003) found that yellow-shouldered Amazons Amazona barbadensis used repaired natural cavities more often than artificial nest boxes. One box of 14 was used in 1997, a second in 1998, and three in 1999 compared with all 15 repaired natural cavities being repeatedly occupied following repair. Fledging rates were also low for nest boxes; with four out of five clutches being removed by poachers (the remaining clutch fledged three chicks). Nest boxes were wooden, 160 x 30 x 30 cm with a 20 x 15 cm entrance hole, had 10 cm of woodchips inside and grooves to allow parrots to climb out. Boxes were placed 2-4 m up in trees, with all used boxes being on Bulnesia arborea trees.
