Radiographic Diagnosis of Egg Binding in Birds


There are few instances of respite from the confusion that most vets feel in analyzing bird radiographs. Identifying an egg is generally one of them – since the normal eggshell is radiopaque and the outline is clear. Radiography is therefore one of the first steps in diagnosing egg binding in birds. However, going about this with a potentially unwell bird can be daunting, and the treatment decisions can likewise be a challenge for a novice bird vet. How can you safely anaesthetise a sick bird to make the diagnosis? How do you decide if the egg is too large?   When do you just give the bird time and when do you need to be more proactive with treatment?

Associate Professor Lorenzo Crosta from the University of Sydney’s Avian Reptile and Exotic Pet Hospital discusses some of these quandaries in this video, giving extremely practical advice from years of dealing with these cases in bird breeding facilities, including Loro Parque in Tenerife, which houses one of the largest and most diverse parrot collections in the world.
