This week let’s meet the biggest parrot in the world, the Hyacinth Macaw. These big beauties from Brazil grow to be about a metre in length from the tip of their tail to the top of their head, easily making them the longest parrot. Only the flightless Kakapo beats them out in weight.

An incredibly striking bird with their bright blue plumes, contrasted with sunny patches of yellow bare skin around their beak and eyes. But their beauty has been the source of problems. For decades, the Hyacinth was poached from their native habitat to be bred in private aviaries and zoos around the world. That coupled with habitat destruction has led to a collapse of their wild populations and today they are listed as a vulnerable species. One of the only upshots of their popularity as an aviary bird is that there are a lot of them in captivity. Now that attitudes are slowing shifting towards conservation, and as habitat is protected and restored, these captive birds may provide the stock to re-seed the species back to their native land.

In the wild the Hyacinth also has a love-hate relationship with another bird, the Toco Toucan. To breed, the Macaw relies primarily on natural hollows that form in Manduvi trees. In turn, the Manduvi tree relies on the Toucan to disperse its seeds throughout the forest. But then the Toucan is a major predatory of the Macaw’s nest, with about 50% of their eggs being lost to predation from the Toucans. It’s one of those sad ironies of life, that the Macaw cannot finding a nesting site without the Toucan, but when it does the Toucan is going to eat its eggs.

It’s a delightful win-win for the Toucan, they get to eat the fruit from the Manduvi tree, spread its seeds to make more trees, and then also eat any Macaw eggs that turn up. They’ve cracked the perfect system, and the poor old Macaw is left to do the best it can. So it turns out it’s a bit of a sad story for the world’s largest parrot.
