The Green-winged Macaw can be up to 49" with a total body length of 39" and will weigh approximately 2.5-3.5 lbs. This bird has a very powerful beak that can generate pressure up to 2000 psi, which can snap a broomstick in half. This powerful beak has evolved to crush or open some of the hardest nuts and seeds.
