Acute pancreatitis in parrots.
Acute pancreatitis was diagnosed in three parrots. Antemortem diagnosis of pancreatitis in the avian patient is rarely documented, and should be suspected in birds showing clinical signs attributable to abdominal pain or gastro-intestinal dysfunction. However, not all birds with confirmed pancreatitis display these signs. A serum amylase level greater than 1,500 U/L is suggestive of pancreatiti...
متن کاملFluorescent signaling in parrots.
Fluorescent pigments appear to glow because ultraviolet (UV) light is absorbed and reemitted at longer wavelengths. Humans use fluorescence as a highlighter, but it remains a mystery whether naturally occurring fluorescence functions as a signal or is a by-product of pigment structure. Here, we test for evidence of signaling using the fluorescent plumage of parrots (1). We performed mate choice...
متن کاملLaterality enhances cognition in Australian parrots.
Cerebral lateralization refers to the division of information processing in either hemisphere of the brain and is a ubiquitous trait among vertebrates and invertebrates. Given its widespread occurrence, it is likely that cerebral lateralization confers a fitness advantage. It has been hypothesized that this advantage takes the form of enhanced cognitive function, potentially via a dual processi...
متن کاملCognitive and Communicative Abilities of Grey Parrots
Grey parrots (Psittacus erithacus) solve various cognitive tasks and acquire and use English speech in ways that often resemble those of very young children. Given that the psittacine brain is organized very differently from that of mammals, these results have intriguing implications for the study and evolution of vocal learning, communication, and cognition. For 25 years, I have taught Grey pa...
متن کاملAvian Malaria Deaths in Parrots, Europe
feline strains from Italy and Australia grouped together, as did the P[9] strains from the United States. Thus, both the VP7 and VP4 genes of G3P[9] strain identifi ed in this study were most closely related to a racoon dog rotavirus strain (RACDG5), suggesting an animal origin of this rotavirus strain. These strains are likely an example of an animal strain causing limited disease in humans, r...
