RESUMO
The amount of research on metabolic bone diseases in commercial birds is considerable, however, there is a large gap in the knowledge of these diseases in wild birds. Aspects related to diet are the main factors that cause these diseases, such as: vitamin D deficiency, insufficient calcium intake, or imbalance of calcium and phosphorus in the diet, and problems in the absorption and metabolism of these compounds. This study reports two cases of bone diseases in birds of the order Accipitriformes, which are wild in the state of Paraíba, a crab-eating hawk with rickets, and a caboclo hawk with fibrous osteodystrophy. The diagnosis in both cases was based on macroscopic and microscopic findings. These reports are subsidies for the bird clinic of the order Accipitriformes and for the maintenance of these birds in nurseries and zoos. This study demonstrates the need for further studies to assess whether such cases can be used as indicators of environmental imbalance.(AU)

Background: Buteo magnirostris, popularly known as roadside hawk belongs to the family Accipitridae, Ciconiiformes. The specimen is common throughout Brazil inhabiting open areas, tolerating disturbed areas very well, but avoiding dense forests. The trematodes are common parasites in the intestines of birds of prey, with scant notice of pathogenic infections. However, severe infections of trematodes Strigeidae family have been previously reported as a cause of anemia, diarrhea, enteritis, weight loss and death. This paper aims to report the occurrence of infection in S. Falconis in B. magnirostris diagnosed by post mortem examination.Case: The specimen of B. magnirostris, male, young was sent for necropsy at the Laboratory of Veterinary Pathology, Federal Rural University of Semi-Arid (UFERSA), Mossoró-RN, Brazil. With a history of apathy, anorexia, diarrhea and death in one course of 24 h. The free bird life and even puppy had been captured for training and practice of falconry shortly before the clinical manifestation of infection (time of captivity uninformed). On physical examination ruffled feathers, cachexia and pallor of skeletal muscle was observed. At necropsy there was severe enteritis with petechiae and accumulation of liquid contents into the duodenum. Fifty-two trematodes were found set in duodenal mucosa. The other organs and structures showed no changes...
Buteo magnirostris, conhecido popularmente como gavião-carijó, pertence à família Accipitridae, ordem Ciconiiformes. O espécime é comum em todo território brasileiro habitando áreas abertas, tolerando muito bem áreas antropizadas, porém evitando matas fechadas [9].Os trematódeos são parasitos comuns no intestino de aves de rapina, sendo escassa a notificação de infecções patogênicas. [3,7]. Todavia, infecções severas por trematódeos da família Strigeidae foram previamente relatadas, como causa de anemia, diarreia, enterite, perda de peso e óbito [7]. Estes parasitos apresentam ciclo de vida complexo e necessitam passar por três diferentes hospedeiros intermediários para completar seu ciclo evolutivo [4].O trematódeo adulto localizado no intestino delgado do hospedeiro definitivo libera ovos, que vão com as fezes do hospedeiro ao meio ambiente. Encontrando água, os miracídios deixam o interior dos ovos e penetram em caramujos aquáticos, onde se desenvolvem até a fase de cercária. A qual deixa o molusco e começa a parasitar anfíbios, formandos nestes, a fase de mesocercaria. O anfíbio ao ser predado por um vertebrado repassa o parasito, que evolui para metacercaria. O hospedeiro definitivo se infecta ao ingerir o vertebrado contendo a metacercaria [3]. Este trabalho tem por objetivo relatar a ocorrência de infecção por S. falconis em B. magnirostris diagnosticado por exame...
