Abstract The caracaras belong to a group of falconids with widespread geographical distribution in the Western Hemisphere, particularly in South America. Here we report fossil remains of a new species attributed to the genus Caracara from the late Pleistocene of Uruguay. This bird would have had an estimated body mass of 3700 grams, a value that greatly exceeds the maximum body mass reported for living falconids. Apparently, it would have had flying capabilities, in contrast to another… Expand
A new fossil species of small crested caracara (Aves: Falconidae: Caracara) from the Pacific lowlands of western South America
Abstract A new species of small crested caracara, Caracara seymouri, from Quaternary asphalt deposits of the Talara Tar Seeps, northwestern Peru, is described from most major elements of theExpand
Two species of Uria (Aves: Alcidae) from the Pleistocene of Shiriya, northeast Japan, with description and body mass estimation of a new species
The genus Uria includes volant wing-propelled diving birds widely distributed in the Arctic and boreal waters in the Northern Hemisphere. It includes two Recent species, U. lomvia and U. aalge, whichExpand
First report of large cathartids (Aves, Cathartidae) from the late Pleistocene of Uruguay
Abstract The fossil record of South American cathartids, with few exceptions, is largely restricted to Late Pleistocene and Holocene sites. This contribution provides for the first time fossilExpand
Mid-Holocene Falkland Islands bird bones from a peat deposit, including a new species of caracara
This paper provides a more detailed analysis of more recent focussed excavations of subfossil remains of the Falkland Islands, summarising their known history and dates them at over 5000 years before present. Expand
A New Pleistocene bird assemblage from the Southern Pampas (Buenos Aires, Argentina)
Abstract In the present paper we report the most complete fossil avifauna from the southern cone of South America. The specimens here described were collected in the Paso Otero locality, at theExpand
A record of a landbird (Telluraves) from the Eocene Ikovo locality (East Ukraine)
First remains of a landbird from the Eocene (Lutetian) marine deposits of the Ikovo locality in Ukraine are described here. These include a single coracoid bone of an immature individual. TheExpand
Ancient DNA from a 2,500-year-old Caribbean fossil places an extinct bird (Caracara creightoni) in a phylogenetic context.
The recovery of a nearly complete mitochondrial genome from a 2,500 year old (late Holocene) bone of an extinct species of bird, Caracara creightoni, recovered from the anoxic saltwater environment of a blue hole in the Bahamas is reported. Expand
The last terror birds (Aves, Phorusrhacidae): new evidence from the late Pleistocene of Uruguay
AbstractWe report new fossil evidence of terror bird survival until the end of the Pleistocene in Uruguay. The new specimens comprise the distal portion of right tarsometatarsus and a left humerus;Expand
Skeletal Correlates for Body Mass Estimation in Modern and Fossil Flying Birds
This study generates thirteen body mass correlations and associated measures of statistical robustness using a sample of 863 extant flying birds and suggests that the most precise proxy for estimating body mass in the overall dataset is the maximum diameter of the coracoid’s humeral articulation facet (the glenoid).

Further characterization of Caracara creightoni Brodkorb based on fossils from the Quaternary of Cuba (Aves : Falconidae)
•Caracara creightoni, previously known from three fragmentary fossils from New Providence Island, Bahamas, is here documented from two Quaternary sites in Cuba. It appears to have been a smallerExpand
A New Species of Large, Terrestrial Caracara from Holocene Deposits in Southern Jamaica (Aves: Falconidae)
Abstract A new species of caracara, Caracara tellustris, is described from cave deposits in the arid Portland Ridge area of southern Jamaica. It is characterized by great size and much reduced wings,Expand
Studying plumage characters and measurements of over 392 museum specimens and found no evidence of clinal change between the northern and southern continental populations, it is concluded that three biological species can be identified in the crested caracaras: the insular Guadalupe Caracara (Curacara lutosus); and two continental species, Northern and Southern caracara, neither of which shows subspecific variation.

Phylogeny and Taxonomy of the Patagonian Miocene Falcon Thegornis musculosus Ameghino, 1895 (Aves: Falconidae)
The ecotonal margins produced by the vanishing of humid forests that developed during changes in Patagonian plant communities throughout early Neogene times are hypothesized as a plausible scenario to understand the evolution of this basal clade of falcons. Expand

Ecological and reproductive constraints of body size in the gigantic Argentavis magnificens(Aves, Theratornithidae) from the Miocene of Argentina
Abstract. Several estimates of ecological and reproductive parameters are offered for the giant Argentavis magnificens (Teratornithidae), from upper Miocene localities in Argentina. Using theExpand
VERTEBRATE RECORDS | Late Pleistocene of South America
Late Pleistocene vertebrate communities of South America were strikingly different from current ones, largely because most of the large and all megavertebrates died out at the Late Pleistocene/earlyExpand
Exceptionally well preserved late Quaternary plant and vertebrate fossils from a blue hole on Abaco, The Bahamas
The exquisitely preserved fossils from Sawmill Sink suggest a grassy pineland as the dominant plant community on Abaco in the Late Pleistocene, with a heavier component of coppice (tropical dry evergreen forest) in the late Holocene. Expand
A New Species of Caracara (Milvago) from Quaternary Asphalt Deposits in Cuba, with Notes on New Material of Caracara creightoni Brodkorb (Aves:Falconidae)
An extinct caracara, Milvago carbo, new species, is described from Quaternary asphalt deposits of Las Breas de San Felipe, northern Matanzas Province, Cuba, from tarsometatarsi, tibiotarsi, and aExpand
This work serves as a compendium of anatomical resources upon which a companion phylogenetic analysis of Aves and related Theropoda (Avialae) was based and summarized, to the extent feasible, previously published characters for which inclusion in the present work was judged to be unreliable or lacking sufficient clarity.
