A Comparison of Feathers and Oral Swab Samples as DNA Sources for Molecular Sexing in Companion Birds. [PDF]

Animals (Basel), 2023
The early age determinism of the sex in case of monomorphic birds is very important, because most companion birds have no distinct sexual dimorphic traits.

Polyomavirus Infection in Two Young Parrots: Assessment of Viral Distribution in Organs and Affected Tissues. [PDF]

Vet Med Int
Avian polyomavirus (APyV) is responsible for diseases in birds belonging to several avian orders, including Psittaciformes, Anseriformes, and other susceptible taxa. APyVs appear to be able to replicate in various organs of susceptible bird species.

The Role of Two Tyrosinase-Like Glycoenzymes in Defining the Final Hue of Parrot Plumage. [PDF]

Pigment Cell Melanoma Res
ABSTRACT Recent advances in avian melanogenesis have pinpointed multiple genetic loci associated with color polymorphisms, predominantly in the plumage of chickens, quails, and pigeons. However, the genetic basis of melaninization in parrot plumage remains elusive.
