MOLECULAR PHYLOGENETICS OF THE BUTEONINE BIRDS OF PREY (ACCIPITRIDAE)
The Auk, 2008Abstract Phylogenetic relationships among birds of prey in the subfamily Buteoninae are not fully established but are of particular interest because the Buteoninae constitute one of the largest accipitrid subgroups and include multiple species of conservation concern. Genera previously included within the Buteoninae are Buteo, Leucopternis, Buteogallus,

The rufous crab hawk (Buteogallus aequinoctialis) is a crab-eating specialist restricted to South American mangroves. Even though it is considered Near Threatened, with presumed population declines, its breeding biology remains poorly studied.

Taxonomy and distribution of the Pygmy Eagle Aquila (Hieraaetus) weiskei (Accipitriformes: Accipitridae) [PDF]
We re-evaluated the taxonomic status of the New Guinean subspecies weiskei of the Little Eagle Aquila morphnoides and confirmed that it differs considerably from the Australian A. morphnoides in multiple morphological and plumage characters. Genetic differentiation in published mitochondrial cyt-b and ND2 sequences between the nominate subspecies and ...

Exposure of Threatened Accipitridae to Mycobacterium bovis Calls for Active Surveillance
EcoHealth, 2017Anthropogenic activities have cumulatively led to the dramatic decline of world populations of vultures that currently face serious survival challenges in several regions of the world. In Portugal, the three resident species qualify as endangered and are under conservation efforts, mainly in the central east and south-east regions, where habitat ...

Chromosome banding studies in the Bateleur (Terathopius ecaudatus, Aves, Accipitridae).
Chromosome research : an international journal on the molecular, supramolecular and evolutionary aspects of chromosome biology, 1998The karyotype of the Bateleur (Terathopius ecaudatus) was studied with conventional and Ag-NOR staining, and using GTG and CBG banding. The karyotype organization is typically accipitrid, with satellites and few microchromosomes, close to the karyotypes of true vultures.

Doomed to die? Predicting extinction risk in the true hawks Accipitridae
Animal Conservation, 2008AbstractOne of the most important tasks in conservation biology is identifying species at risk from extinction and establishing the most likely factors influencing this risk. Here, we consider an ecologically well‐defined, monophyletic group of organisms, the true hawks of the family Accipitridae, which are not only among the most studied, but also ...

Evidence for heterochrony in the evolution of the goshawk Accipiter gentilis (Accipitridae, Aves)
Annales des Sciences Naturelles - Zoologie et Biologie Animale, 1999Abstract An analysis of the growth patterns of two close relatives of the genus Accipiter (the European sparrowhawk A. nisus and the European goshawk A. gentilis) was conducted, in order to elucidate a possible mechanism for the evolution of the ontogeny of the goshawk from that of its presumed smaller ancestor.

Evolution of Karyotype Organisation in Accipitridae: a Translocation Model
2000We propose a model of evolution of the atypical karyotype of Accipitridae species (diurnal raptors) from the classical avian karyotype, based on computer simulations of translocations.
