I was going to say a Mealy Amazon too...Again, birds don't have "breeds" like dogs, but rather different "Species" or "Sub-Species"...
And to find out the gender you'd have to have a DNA test done, as already described...If you don't already have one, you need to find either a Certified Avian Vet or an Avian Specialist Vet (No "Exotics" Vets or General Vets), and your bird should be getting a full Wellness-Exam done at least once a year with this CAV or Avian Specialist Vet...The full Wellness-Exam should include a full visual and physical exam of your bird, a Fecal Culture to be sent-off to a lab, and then they should also do Microscopy/Gram-Stain on the Fecal sample right there in the office on the spot (this is to check for any bacterial, fungal/yeast, or protozoan infections, and to check to make sure your bird has a proper amount of normal, "healthy" bacteria throughout his GI Tract; and then finally should ALWAYS include routine, "Baseline" blood-work, which will check for any infection, anemia, any nutritional deficiencies, check his metabolic levels, and then his liver and kidney functions....That's the minimum that should be done at least once a year, while some people also have a regular x-ray done as well, just to check for any masses/growths and to see the size of their liver to make sure that they are not suffering from Fatty Liver Disease, and to check the size of the kidneys to check for any Renal infections...And then you'll also have his normal, "baseline" levels to compare to if he ever becomes ill...And they can also add a DNA-test to the blood-work so you'll know the gender of your bird for certain.
If you need help finding a Certified Avian Vet or Avian Specialist Vet nearest to you, we can help you with that as well. It's extremely important that you find an experienced, educated Avian Specialist Vet and not just an "Exotics" Vet, as at least in the US they have no extra education or training in any specific types of animals, they are simply General Vets who are "willing to see" animals other than dogs and cats, and birds are so unique and specialized in their anatomy and physiology, and Avian medicine in-general is so specialized that you really do need a CAV who knows what they are doing...plus it's good to establish a relationship with a CAV just in-case your bird ever becomes seriously ill or injured...
