The city is for some birds their most important living area.
These city birds are depending on human buildings, and look for holes to build their nests in. Now only well isolated buildings are build, to perfect without small holes and openings. The city birds are now unable to find nesting spaces. And they are now added to the endangered species list for birds. These city birds will disappear if humans remain building their homes without space for the birds.
These Bird Bricks are specially designed for 3 different endangered city birds. The Bird Bricks can be build into any brick building. Starting at 2m high up to any height wanted.
