We studied the mechanism of song production in the outbred common or domestic canary (Serinus canaria). The contribution that each side of the syrinx makes to song was investigated by observing the effect of unilaterally occluding the left or right primary bronchus, followed by section of the ipsilateral branch of the tracheosyringeal nerve. In other birds with a bilaterally intact vocal system...

This paper introduces two concepts: Canary Files and a Canary File management system. A Canary File is a fake computer document that is placed amongst real documents in order to aid in the early detection of unauthorised data access, copying or modification. The Canary File acts as a hidden watermark for a file directory containing critical documents; the Canary File and its contents can be use...

The visual receptors of the passeriform bird Serinus canaria, the canary, have been examined microspectrophotometrically and the sequences of the opsins determined. Rods have a maximum absorbance (lambda max) at 506 nm. Four spectral classes of single cone are present: long-wave-sensitive (LWS) containing a photopigment with lambda max at 569 nm, middle-wave-sensitive (MWS) with lambda max at 5...

Serinus canaria is a widespread domestic ornamental songbird, whose limited knowledge of biology make compelling studies aimed to monitor stress. Here, a commercial enzyme immunoassay was adopted to measure immunoreactive corticosterone (CORT) in single Serinus canaria dropping sample, to monitor the daily fecal excretion of CORT in birds bred singly or in-group and to detect the effect promote...

ABSTRACT: The domestic canary (Serinus canaria) has been bred for hundreds of years to improve the quality its plumage and song. Reproduction in this species occurs seasonally, stimulated by a gradual increase day length. Although, occurrence seasonal breeding canaries is well known, whether reproduction can be manipulated remains unknown. Our objective was determine conditions captivity (photo...

A dead canary from a mixed species zoological garden was presented for diagnostic necropsy. Cachexia with prominent atrophy of pectoral muscles, yellowish brown discoloration of the liver and kidney, dark brown to black intestinal contents and moderate proventricular dilatation with some degree of catarrhal gastritis were the significant macroscopic findings. Parenchymatous organs like the live...

Little is known about the presence of methicillin-resistant Staphylococcus aureus (MRSA) in a canary bird (Serinus canaria domestica). Although MRSA was previously reported, to best our knowledge, this first full description isolation and antibiotic resistance pattern pet bird. A swab taken from nonhealing wound on lateral thigh four-year-old, caged, housed alone, male After identification aure...

Songbird species (order Passeriformes, suborder Oscines) are important models in various experimental fields spanning behavioural genomics to neurobiology. Although the genomes of some songbird species were sequenced recently, the chromosomal organization of these species is mostly unknown. Here we focused on the two most studied songbird species in neuroscience, the zebra finch (Taeniopygia gu...
