This photo of of a Red-throated Caracara was taken by Manfred Bienert on April 18 near the village of Bijagua, which is just adjacent to of the Reserva Biológica Indio Maíz and close to the Costa Rican border. It shows one individual of a group of six perched high in a tree with a piece of wasp nest (Polybia spp.).
This photo is important documentation of the continued presence of Ibycter americanus in Nicaragua, where they are considered extremely rare, having declined across most of Central America over the past several decades.
Despite the status of the Red-throated Caracara across much of this region, there are no formal conservation plans for these birds as they are not in danger of going globally extinct. In this way, the statistics used by the International Union for Conservation of Nature (IUCN) can be misleading on a regional scale, as when a species is labelled “Least Concern” it misses out the fact that the bird may be disappearing in many countries.

In Mexico, Red-throated Caracaras have been considered extirpated for some time, although it was previously present in Oaxaca, Chiapas , and Veracruz . They are listed as critically endangered in the Republic of Costa Rica , and “probably extirpated” in Guatemala [4,5]. In Honduras, the species has only recently been rediscovered after being largely extirpated since 1955 . In Panama, they are considered vulnerable.
Factors responsible for these declines have not been identified, although habitat destruction is probably involved. Illegal shooting of birds could also be a factor, as they are likely to have a very slow rate of reproduction and a highly developed cooperative breeding system (we documented a group of 6-7 adults caring for a single chick) .
I am glad to see that these impressive wasp-loving birds have not completely disappeared from Nicaragua, and am grateful for people like Manfred Bienert for documenting the wonderful birds of the region.
