The birds died with characteristic clinical signs, and post-mortem examination revealed a highly distended proventriculus. Upon light microscopic examination, most of the ganglia of the gastric plexus and some of the duodenal myenteric plexus appeared destroyed and ...

HEAD‐SCRATCHING IN THE PSITTACIFORMES

Ibis, 1962

A standardised ethogram for the Psittaciformes

Behavioural Processes
The standardisation of ethograms offers behavioural researchers many practical advantages. They make it possible to describe behavioural repertoires and their occurrence in different contexts accurately. As there is no standardised ethogram for Psittaciformes in the scientific literature, this study aimed to create one by compiling information from ...
