The current issue of Smithsonian Magazine has an interesting article on efforts to propagate avian species. An imaginative person invented an electronic egg, which records temperature and humidity, as well as how often it is turned, when someone is sitting on it, etc.
Researchers are learning that some kinds of birds sit on their nests less often than they thought, and that some kinds of eggs are exposed to drier, colder conditions than they expected. All of this data will help people do a better job of incubating eggs.
I mention all this because bustards feature in the article.
