My family had a male golden growing up along with my cockatiels. I don't remember a single close call involving the golden around the cockatiels. I have heard of a golden killing a scarlet macaw several years ago, but I believe the owner walked out of the house and left them together unsupervised which was not smart. Our golden was not the healthiest individual though. Lots of skin problems, ear problems and on thyroid medicine. Oh and epilepsy for his last several years. Thankfully, he did miss out on the cancer that is so common...unless it was undiagnosed and causing the seizures. Every time dad took him hunting, the dog would need a vet visit for skin problems and hot spots or ear infections. He was just more prone to those problems than other sporting breeds we've had(labs, griffons and spaniels). Our golden had temperament issues too. He was the only dog to ever bite me and I've got the scars to prove it still 30 years later. He did a lot of resource guarding. I don't believe those problems are typical of the breed though.
Personally, I'd go with a mini-aussie, sheltie, border collie or actually almost any other retrieving or spaniel breed other than a golden. Despite the temperament problems our dog had, I still like the breed and have been impressed with the apparently very sweet soul that many of them posses. The cancer issues compounded by my own experience with nickel and dime vet trips for a multitude of small stuff scares me away from ever getting another golden. He was just a high maintenance dog and not that great of a personality to anyone except my dad.
As for male vs. female. If getting a large retriever or pointing breed, I'd go female when in doubt. I've known a number of male labs and obviously our golden that were just jerks for lack of a better word. Prone to running off and not coming when called, or only responding to commands given by alpha type family members, some attempts at pushing lower family members and strangers around. I usually prefer male dogs myself and currently have a very soft tempered male springer spaniel who is great with the birds inside. He was just out flushing quail and rabbits a few days ago for my harris hawks, but I've never had a close call with him around my parrots since he was a very small untrained puppy. Springers have their own serious temperament issues though too if you aren't careful of the bloodline. I think male vs. female is breed dependent. I would not discriminate based on sex for the collie or aussie type hearding dogs though. Just met too many sweet males.
