Figure 8. Nest box occupancy of Blue-throated Macaw and number of fledglings presented over the 14 years of Armonía’s nest box program. The 2018-2019 breeding season resulted in the highest ever Blue-throated Macaw nest box occupancy (9) and the highest ever number of successfully fledged chicks (12). Over the 14 years, a total of 81 Blue-throated Macaws successfully fledged Armonía’s nest boxes
Figure 9. Nest box occupancy of Blue-throated Macaw vs Blue-and-yellow Macaw presented over the 14 years of Armonía’s nest box program. Since Armonía started experimenting with entrance size (from 12 by 25cm to 10 by 10cm) between 2013 and 2015, competition between these large macaws significantly dropped.
