The Grey-bellied hawk (Accipiter poliogaster) is a rare diurnal raptor of the Accipitridae family and is distributed throughout the Neotropics. BirdLife has it listed as a “near threatened” bird and, despite their wide distribution, it is one of the least known of the raptors. In Peru, it occurs in the eastern side of the country, mostly in lowland tropical forests, and has been also reported along forest edges, and fragmented forest. Since 2015, birders at Los Amigos have been able to observe and admire the beauty of this raptor. This represents a unique opportunity to learn and increase the scarce knowledge about this species. In this note, we recapped A. poliogaster sightings at Los Amigos (LA).
In June of 2015, a Peruvian researcher specializing on raptors (R. Piana), found a juvenile A. poliogaster hunting at the forest edge near the Los Amigos River, at LA. The following year, September of 2016, Fernando Angulo (LABO Advisory member) and R. Piana located a reproductive pair defending their territory located ~1 km away from the station. Both individuals were sighted in the same location on consecutive days after the first encounter. On April of last year, a Peruvian bird guide, identified a juvenile of this species around LA garden, close to the territory identified the previous year. Lastly, on mid-April of the present year (2018), two juvenile individuals were located on a nest situated on an emergent tree and in the same territory of the reproductive pair previously identified. These events prove that A. poliogaster is breeding and nesting within the Los Amigos Biological Station, making this place a unique study site for this species.

The first recorded observation of the reproductive behavior and biology of A. poliogaster were described in Southern Brazil few years ago, where an adult female was observed incubating two eggs and an adult male was actively hunting. Only one nestling survived, and after ~49 days post-hatching the nestling left the nest. The fledging was fed by the female for ~90 days post-hatching. Given the importance of raptors in Neotropical forest, and LABO’s goal to increase the knowledge and conservation efforts of Neotropical avifauna, one of our Franzen fellows, Igor Lazo, will be assessing the ecology and natural history of A. poliogaster at LA, being the first study of this species in Peru. The information coming out from this project will create a firm foundation for further research on the Grey-bellied hawk!

We have been working with the açaí and Brazil nut harvesters, who depend on the Santa Rosa de Abuná conservation area for their livelihood, to improve how they locate, gather, and process the forest goods they sustainably harvest. This is a key conservation and community development strategy for providing local people with the incentive to keep forests standing, as many of the globally in-demand fruits and nuts they harvest can only grow in healthy forests – not in large-scale plantations. With this strategy in mind, we help families improve their income by growing their local economies through instituting ecologically sustainable activities that protect the forests they call home.
The new harnesses have already proved their value. One of the açaí harvesters, Omar Espinoza, used the new harness to climb a 50-foot high açaí tree, which he does on a daily basis during the harvest season in order to collect the fruit that generates almost all of his family’s income. Due to a misstep coming down the tree with a heavy branch of açaí in hand, Omar fell from a height of about 40 feet, head first. Thanks to one of the features in our safety harnesses – aptly called a “life line” – he was stopped from hitting the ground and just dangled from the harness instead. His head was just a few feet from the ground. Using the harness he had before this project would have meant a certain fall. Had it not been for this new equipment, he would have faced severe and debilitating injuries or possibly, death.
