Hyacinth macaw
This beautiful bird is endangered. In the wild its eggs are eaten by various small mammals, by vultures, and by the toucan. The hyacinth depends on the toucan, which spreads the seeds of the Manduvi tree (Sterculia apetala) that the macaw needs for reproduction. The tree is just right for the macaw to make its nest, and there are few other places as good. The toucan disperses 83% of the tree's seeds, but also eats 53% of the macaw's eggs.
