Highly recommend any pet with screech. I tamed my first bird (owl in Felwood) at 50, I've switched specs to/from Marks and BM (with gear for each) and I've never had any issues pulling agro off my bird.

That being said, I recommend 2 hunters with birds, just in case and both have at least the talents for pet armor and health (if not full BM) The birds keep agro very well, but that doesn't mean they live a lot longer vs elites.

On my hunter (single box a long time ago) I had the cheaper mana pet heal talents, the increased focus regen talents and (when I got high enough level) the Marksman talent for focus on crits. Put screech on auto cast, and no agro issues. Ever.
