RESUMO
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. A further two white-headed pigeons presented 7 and 21 days postexercise with similar lesions. Treatment with fluids, physiotherapy, and analgesia was unsuccessful. This is the first report of deep muscle necrosis in Columbiformes.

The case history and clinical signs of a fatal self-envenomation event by a brown tree snake, Boiga irregularis, in South-east Queensland, Australia, are presented. Clinical signs began 20 minutes post-envenomation with muscle twitching, ataxia, and heat seeking behavior which progressed to partial paralysis by 6 hours, generalised paralysis and respiratory arrest at 10 hours and cardiac arrest by 12 hours post-envenomation. Clinical signs are suggestive of potent neurotoxicity for B. irregularis to its own venom.
