Data from monitoring hundreds of nests from Blue and Gold, Red and Green, and Scarlet Macaw nests show that:

.	Natural, PVC, and wooden nest boxes all have vastly different hatching success rates. Natural nests have a hatching success rate of 65% while the PVC nest boxes commonly used around TRC have hatching rates of only 41%. The hatching rates in wooden boxes may be higher (80%) but the sample sizes are too small to draw any conclusions.
.	Twenty four percent of all Scarlet Macaw chicks monitored (9 of 37) died of starvation or would have if the researchers had not intervened. Our findings suggest that sibling competition and not the overall food supply may be the determining factor in chick survival, but larger sample sizes are needed to confirm these preliminary findings.
.	Dipteryx micrantha and Mauritia flexuosa are keystone tree species for parrot nesting in southeastern Peru. Clearing for agriculture, targeted destruction of parrot nests by collectors and selective felling of key species will reduce the density of suitable nest cavities.
.	Across three studies (two in Costa Rica and the one in Peru) a total of 71 Scarlet Macaws have been released. The combined first-year survival post release was 74% and the post first-year survival was 96%. Breeding attempts have been recorded at all three sites and hand-raised birds with wild mates have successfully fledged young in Peru. Supplemental feeding post release played an important role in establishing a core flock at all three release sites.
