Birds
Birds (Aves) are quite a plentiful category of vertebrates. We can count about ten thousand species. People have always been fascinated by their ability to fly and in some cases also by their beautiful singing. Now, we admire their incredible sense of direction (they are able to sense magnetism of the Earth and work with it), intelligence (using tools) and connection with dinosaurs, from which they developed. Unfortunately, a lot of mates of birds are endangered species and some of them are on the border of extermination. In the Czech Republic, we can see the biggest decrease in birds of fields, water and wetlands. There are main problems birds have to deal with: destroying of baulks, draining wetlands, and imprudent management of ponds.
