Surgical Sexing Birds

We see a number of different breeds of birds over the year. From canaries, budgies, lorikeets and cockatiels to black cockatoos, conures, eclectus parrots and even the odd macaw. The majority of these breeds can be sexed accurately by distinguishing markings (THEY ARE KNOWN AS DIMORPHIC WHERE MALE AND FEMALES HAVE DISTINCTLY DIFFERENT MARKINGS) e.g. the male cockatiel is yellow faced with a red ear patch with the female is pale faced with barred tail, or eye colour e.g. galah males are brown eyed and females are red eyed.

A number of bird breeds are monomorphic (WHERE MALES AND FEMALES LOOK IDENTICAL) and require surgical sexing to determine their gender. This ensures pairs aren't the same sex and will eventually breed successfully. Surgical sexing of birds is performed at our hospital.

Lorikeets are also beautifully marked



The arthroscope is passed into the abdomen to view the single ovary in females or the double testies in male birds.
