One initiative, which has been in progress for Useveral years, is to train and support people from local communities in the Red-tailed Amazon breeding zone to keep native species of bees. The objectives include to help the native bees sustain healthy populations, and to provide local people with an additional source of income from the sale of honey, which in turn gives them an incentive to help protect the forest. The native bee species most favoured for honey production is the Yellow jataí (Tetragonisca Two well-feathered angustula). chicks at the entrance to a natural nest. During the 2019/2020 breeding season in Paraná, the lowest number of hatchings of Red-tailed Amazons in the last ten years was recorded. A total of 105 cavities What kind of mattress suits you best for a good night’s suitable for forming nests were monitored, of which 74 sleep? Is it the spring kind, or foam, or maybe air or eventually had breeding activity. A total of 155 eggs were water, or even one that has hexagonal cells called a laid, from which 69 (44.5%) chicks hatched. Of those, only honeycomb base. If it is the latter, you are sharing this 15 (21.8%) successfully fledged. On the south coast of honeycomb experience with the Red-tailed Amazon São Paulo State, 23 suitable nest cavities were monitored, (Amazona brasiliensis) except that, in the case of the with only five of them showing breeding activity. In those, parrot, it is real honeycomb. This has been observed in a nine eggs were laid, seven chicks hatched and five of long-running project of the Brazilian NGO, the Society for them successfully fledged. The poor results are surprising, Wildlife Research and Environmental Education (SPVS), the numbers being 34% lower than those recorded for the for the conservation of this species throughout its coastal previous breeding season, and similar to the results prior distribution in south-east Brazil, especially in the State of to the installation of artificial nests from 2003.

The Red-tailed Amazons nest in forest of the low-lying islands and neighbouring coastal plains, where they Flying a drone face diverse challenges to reproduce successfully. One (indicated with of those challenges is that suitable nest cavities, both red arrow) over natural and artificial, can become colonised by introduced forest to monitor aggressive Africanized honeybees (Apis mellifera). While Red-tailed the bees are in residence the parrots are excluded, but Amazon nests. after the bees vacate a nest, the parrots return to use the cavity again in the following breeding season. Pieces of broken honeycomb piled-up on the cavity floor, although not the usual substrate, do not deter the breeding amazons. Indeed, one can imagine that the body heat from the chicks (and brooding female) gradually softens the honeycomb in a way somewhat akin to a natural memory foam! 4 LORO PARQUE FOUNDATION Red-tailed Amazon chicks hatched on old honeycomb.
