 In the wetlands of Pantanal an endangered tropical bird relies on its nest predator for its perseverance. The tale of the hyacinth macaw (//Andorhynchus hyacinthinus//) involves the tree in which they build their nests (Manduvi trees //Sterculia apetala//) and the main seed disperser of the manduvi tree, which also happens to be the macaw's main nest predator, the toco tucan (//Ramphastos toco//).
-Hyacinth macaws build their nests almost exclusively on the disputed manduvi trees. Taking into account macaw's threatened conservational status, Pizo //et al.// (2008) performed a study to investigate the natural history of its nesting tree species, specially concerning the main seed dispersers of the manduvi tree. The authors found that toco toucans are the main disperser of manduvi, responsible for more than 80% of the dispersal. At the same time, toco toucans are the main nest predator of hyacinth macaws. Most conservation actions focus only on manduvi trees and macaws; however, this study elegantly highlights how species interactions must be taken into account when performing conservational policies.

    * Considering the central role toco toucans play in the system, both as seed dispersor and nest predator, how does a population dynamic model allows coexistence in this system?
-   * As a conservation manager, you might believe that planting more trees would be a plausible plan of action to conserve hyacinth macaws. Explore the effects of such conservational action in your model. Keep in mind that Manduvi trees are part of the diet of toco toucans.

    * Can you think of another conservation policy that could help the endangered hyacinth macaw? How would you incorporate it in your model to learn if it would be effective?

    * Hyacinth macaws need trees older than 60 years to build their nests. How would you incorporate generation time in your model? How does that change your previous predictions about the dynamics of the system?
