El águila Harpyhaliaetus solitarius es una rapaz neotropical poco conocida y escasa. Con sólo dos nidos descubiertos para esta especie, existen pocos datos sobre su biología reproductiva, hábitat de anidación, período de emplumamiento o su dispersión juvenil. Observamos a una pareja con un juvenil volantón durante un período de tres meses, desde ju...

... first observed the juvenile on 31 July 2009. It was perched in a Caribbean Pine (Pinus caribaea), picking at an epiphyte and hopping clumsily between the branches. This was the same location where we observed both adults on 27 July 2009. Based on the juvenile's behavior and fresh Basic I plumage (Fig. 1), we believe it had recently fledged and was close to the nest tree. The next day we observed the juvenile vocalizing and perched on a snag on top of the ridge 300 m away from the previous day's observation. During subsequent sightings, we noted an obvious im- provement in its flying ...

... Solitary eagles are likely to inhabit more southerly stretches of the Sierra Madre Oriental, as suitable habitat also exists there. Importantly, those pine-oak and broad-leaved forests also contain snake species that are the eagles' prey, such as Mastigodryas melanolomus, Spilotes pullatus, and Lampropeltis annulata (Seminario et al., 2011;Phillips, 2012;Lemos-Espinal et al., 2018). We recommend continued surveys for these and other indicator raptor species in northeastern Mexico, including areas such as El Cielo Biosphere Reserve (Tamaulipas), SATBR, San Nicolás de Los Montes (San Luis Potosí), Sierra Gorda (Querétaro), and Tlanchinol (Hidalgo). ...
We report our observation of an adult solitary eagle (Buteogallus solitarius) in northeastern Mexico, in the Sierra del Abra Tanchipa Biosphere Reserve, on 18 October 2019. We took photographs of the solitary eagle for identification and then reviewed available records of its distribution in Mexico from different information sources. Recent sightings of the solitary eagle are very rare in Mexico, and our observation in northeastern Mexico is noteworthy considering (1) the rarity of the species and (2) that our sighting was outside of its known distribution.
... The tarsometatarsi exhibit only characters of specific value, related to (or derived from) differences in raptorial habits between living (see Seminario et al. 2011, Phillips 2012 and fossil species, due to specialisation on particular prey. Some of these osteological characters (see Results), frequently present in other accipitrids, perhaps misled Campbell (1979: 83) who thought Amplibuteo more closely related to Buteo and Geranoaetus than to Harpyhaliaetus. ...
A large, extinct species of Buteogallus Lesson is described from post-cranial elements in Quaternary cave deposits in western Cuba and south-central Hispaniola. The new taxon was approximately the same size as females of the extinct continental B. woodwardi, but more robust. Some fossils, recently documented from Hispaniola as Accipitridae genus and species indeterminate, are probably referable to taxa previously known from Cuba, including the new species described herein. Osteological comparisons of both living and extinct species indicate that the extinct genus Amplibuteo Campbell is synonymous with Buteogallus.

Despite the key role that knowledge on breeding biology of Accipitriformes plays in their management and conservation, survey of the state-of-the-art and of information gaps spanning the entire Neotropics has not been done since 1995. We provide an updated classi cation of current knowledge about breeding biology of Neotropical Accipitridae and de ne the taxa that should be prioritized by future studies. We analyzed 440 publications produced since 1995 that reported breeding of 56 species. ere is a persistent scarcity, or complete absence, of information about the nests of eight species, and about breeding behavior of another ten. Among these species, the largest gap of breeding data refers to the former “Leucopternis” hawks. Although 66% of the 56 evaluated species had some improvement on knowledge about their breeding traits, research still focus disproportionately on a few regions and species, and the scarcity of breeding data on many South American Accipitridae persists. We noted that analysis of records from both a citizen science digital database and museum egg collections signi cantly increased breeding information on some species, relative to recent literature. We created four groups of priority species for breeding biology studies, based on knowledge gaps and threat categories at global level. Group I (great scarcity of information, plus higher categories of threat): Leptodon forbesi, Cryptoleucopteryx plumbea, and Buteogallus lacernulatus; Group II (breeding data have recently increased, but threat categories are high): Spizaetus isidori, Accipiter gundlachi, Buteogallus coronatus, Pseudastur occidentalis, and Buteo ventralis; Group III (“Near reatened” species with still scarce breeding information): Accipiter poliogaster, Accipiter collaris, Buteogallus aequinoctialis, and Pseudastur polionotus; and Group IV (other priority cases): Buteo ridgwayi, Buteo galapagoensis, four eagles (Morphnus guianensis, Harpia harpyja, Spizaetus ornatus and Buteogallus solitarius), Leptodon cayanensis, Accipiter superciliosus, Buteogallus schistaceus, and the three Leucopternis hawks (L. semiplumbeus, L. melanops and L. kuhli). We also discuss the way that novel breeding data can show in what manners di erent species and populations are responding to environmental changes.
... Benesh (2006) observed a pair copulating in 2005 and a juvenile in 2006. In 2009, a pair and fledged juvenile were seen near an Orange-breasted Falcon (Falco deiroleucus ) release site operated by The Peregrine Fund, Inc. (Seminario et al. 2011). In 2011, we observed a Black Solitary Eagle displaying breeding behaviors near the falcon release site and followed it to a nest ~3.5 km away. ...
... The ecotonal nest placement and ophiophagous diet are in agreement with previous reports (Harrison and Kiff 1977; Valdez and Osborn 2004; Seminario et al. 2011). The prey species we identified are found in broadleaf forest (Table 1, Stanford and Meyer 2000), the habitat in which we observed the Black Solitary Eagle hunting. ...
Behavioral observations of the first recorded Black Solitary Eagle (Buteogallus solitarius) nest with a two-month-old nestling in the Cayo District, Belize were made from 7 – 30 June 2011. The nest was in a fork of the main trunk of a Nicaraguan Pine (Pinus oocarpa) with an eastern slope exposure at ~670 m elevation. The nesting area was ecotonal submontane pine forest overlooking deep valleys of broadleaf forest. Observations suggest the species forages for snakes (Genera: Spilotes, Drymobius and Dryadophis) in broadleaf forest habitat at elevations ≤ 400 m. Black Solitary Eagles relied on static soaring to deliver prey to the nest, following an indirect route over mountain contours. Of the observed flights (N=10), soaring averaged 4.65 min, while flapping flight averaged 0.08 min. Soaring duration (N=6) averaged 6.75 min with carried snake prey, but decreased to 2.00 min without prey (N=3). Our notes offer new insights on the habitat use, flight styles and patterns, and other behaviors of this poorly known Nearctic-Neotropical raptor.

The Solitary Eagle (Buteogallus solitarius) is a poorly known Neotropical raptor and many aspects of its natural history remain unknown. The species is often misidentified and confused with other congeners. In Venezuela, its occurrence, based on voucher specimen and photographic records, is restricted to the Cordillera de la Costa Central. Here we report on four new confirmed records of the Solitary Eagle in Venezuela. These records represent a distribution extension (>160 km) from its previously known geographic range within the country.
