Birds are the best engineers!

[Pajarita]

This is an article on a study about birds nests, their design, resilience, etc. And, although when it comes to parrots, it can only be applied to quakers (the only species that doesn't only make a nest but also lives in it all year round), I urge you to read it because it's super interesting and, when it comes to engineering, quakers are AMAZING!
