Prior to The Shattering, the Hyacinth Macaw dropped from Bloodsail Mage, Bloodsail Swashbuckler, Bloodsail Warlock, Bloodsail Sea Dog, and Bloodsail Deckhand in Stranglethorn Vale.
After Patch 4.0.3a this pet became a zone drop in Northern Stranglethorn and The Cape of Stranglethorn.
The Hyacinth Macaw arguably has the lowest drop rate of any dropped pet. So farming for this parrot is a tough grind. You might try farming your auction house instead. Often non-collectors will put this up for a few gold or less, not realizing its true value. A friend of mine managed to nab hers for just two gold! Then again, the odds were in her favor since she spends 80% of her time at the auction house searching for armor that doesn't make her look "fat".
