New records of the Rufous-faced Crake, Laterallus xenopterus (Gruiformes: Rallidae) in Brazil and observations about its habitat

New records of the Rufous-faced Crake, Laterallus xenopterus (Gruiformes: Rallidae) in Brazil and observations about its habitat. The Rufous-faced Crake, Laterallus xenopterus, is a bird that is rarely spotted at Paraguay, central Brazil, and central Bolivia. There are known species records at the Brazilian states of Distrito Federal, Sao Paulo, and Minas Gerais. Here, we provide information about new areas of occurrence for this species in Brazil and detailed observations of its habitats. In October 2012, two individuals were registered in the municipality of Cristalina, state of Goias. In December 2012, the species was found in a new locality of Distrito Federal and at the municipality of Patrocinio, Minas Gerais. In February 2013, a new record for this species was obtained in the municipality of Itiquira, Mato Grosso. In all occasions, the bird was spotted in humid environments, which were characterized by the presence of grass and a thin water layer.

The black lion tamarin Leontopithecus chrysopygus - its conservation and management

The black lion tamarin Leontopithecus chrysopygus originally occurred throughout a large part of the Atlantic forest in the west of the state of São Paulo, Brazil. Today, however, it is restricted to a few isolated forest fragments as a result of deforestation caused by cattle ranching, and urban and agricultural expansion, especially in this century. One of its last strongholds is a small gallery forest at Lencois Paulista in the west-central part of the state. The authors report on a long-term study of this small and isolated population, aimed particularly at providing a basis for the intensive management and conservation of the species and its habitat.

Fibrous Osteodystrophy in a Captive Common Eland Antelope (Taurotragus oryx).

Fibrous osteodystrophy (FO) is a common condition described mainly in domestic species, with only few cases described in wild ones kept in captivity. Herein we report a case of FO in a 2 yr-old female common eland antelope (Taurotragus oryx) maintained in captivity and fed with a horse pelleted ration plus hays. The animal showed a firm bilateral symmetrical enlargement of upper maxillary bones which was submitted to histological evaluation. Microscopic findings were those related to extensive bone resorption and fibroplasia.
