Every month, museum visitors choose an exhibit they like best. The one that caught their eye in February was the Gavia Immer. This is an aquatic bird, which is rare in Greece. These birds are almost exclusively North American species. Its flying speed is as much as 120 km/h during migration.

The Gavia Immer is relatively large (73-88 cm), with a heavy sharp beak and thick neck. His eyes are red, which helps their underwater vision. During the winter, they lose their plumage (pterosaurs), resulting in a temporary loss of their ability to fly. Although there is no racial dimorphism in their species (the two sexes are similar), they experience a seasonal dimorphism. This means that during the breeding season their plumage takes on a more striking and fancy shape! The Gavia Immer feed mainly on fish and to catch their prey, they can withstand up to 3 minutes inside the water!

Gavia Immers are monogamous birds and mate forever. Mating usually takes place on land, near the nesting site, and is repeated daily until the eggs are laid. The area in which they will reproduce is marked and protected physically and vocally by the couple! The male and female, build their nest together and incubate the eggs.

Their distinctive voices, as well as, the arched jumps they make to secure their territory, are often misinterpreted as flirtations by humans, while the British tribes of Columbia attributed them to omens of bad weather.

In Canada and Minnesota this bird is so beloved and famous that it is depicted on their coins.
