Without feather ado, the title of most expensive pet bird goes to ... the black palm cockatoo! Also known as the Goliath cockatoo, this bird is stunning in addition to being incredibly expensive. Instead of having white feathers like you may be used to seeing on cockatoos, the black palm variety has striking smoky gray feathers with bright red patches on their cheeks.
This large cockatoo is very rare, which explains why they cost as much as $20,000. If you're able to swing the high price tag for this fancy bird, you can expect to spend quite a bit on an enclosure, too. Black palm cockatoos need very large cages or an aviary to thrive. And just like their common cockatoo cousins, they require a lot of attention.
