Although a number of other bird species have never been observed to fly, it is not conclusively known that they are incapable of doing so.
Approximately 60 species of flightless birds are still living. In the last 100 centuries, about 166 other species of flightless birds have become extinct, and about half of those still in existence are classified as either threatened or vulnerable. The Common Ostrich is the largest flightless bird, while the Inaccessible Island Rail is the smallest. The following bird species have no ability to fly: grebes, cormorants, penguins, rails, parrots, ratites, and waterfowl. How many can you name? Find a list below:
Birdwatchers look for their own happy moments all over the world. Experience, the best gear, and a little bit of good fortune allow them to spot uncommon birds and take a much-needed vacation from the stresses of daily life. In order to guarantee that the concept of “regeneration” extends beyond human populations to include threatened bird species, ZEISS is supporting multiple environmental conservation initiatives and serves as the BirdLife Species Champion for the Spotted Greenshank.
