Exercise-induced deep pectoral necrosis in white-headed pigeons (Columba leucomela).

Abstract: Two white-headed pigeons (Columba leucomela) developed deep pectoral myopathy 2 days after vigorous exercise associated with capture. Clinical signs included lethargy and an inability to raise the wings above the head. Gross pathology consistently revealed marked pallor and edema of the supracoracoideus muscle, and histopathology revealed severe myofiber degeneration.
