Although ostriches are very large and unable to fly, (the largest flightless bird in existence) they are capable of swimming. Though not very quickly. They have been known to swim successfully across strong currents. One was even seen swimming across a flooded area when Hurricane Katrina hit in 2005.
The way these birds are equipped most likely only works to their advantage when it comes to swimming. Their long, bare necks are flat and they have long, powerful bare legs and strong feet with two sharp claws on each foot. Their massive leg muscles enable them to deliver a powerful kick which can seriously injure or kill an attacker, and are very helpful when kicking to and fro to swim. Another interesting fact to know is that ostriches can only kick forward.
These powerful birds contain their main musculature in the hips and thighs so it comes as no surprise that they are able to swim quite well. Their long legs enable them to run at speeds of over 65 kilometers (40 miles per hour). These birds prefer savannah, grassland and semi desert habitats where water sources are also available. They enjoy water, swimming, and taking baths.
