Flamingos In Austria: A Natural Oddity Or Nonexistent?

Austria is home to a diverse range of bird species, with a total of 458 species recorded in the country as of July 2023. Among these feathered inhabitants, one particular species that stands out is the flamingo. These tall, wading birds with their distinctive curved beaks can be spotted in certain parts of Austria, adding a touch of tropical flair to the European landscape. So, are there flamingos in Austria, and if so, where can they be found? Let's delve into this intriguing topic and explore the presence of flamingos in the Alpine nation.

Flamingos are found in Salzburg, Austria

Salzburg is home to the Greater Flamingo, or Phoenicopterus roseus, a species of flamingo that typically stands between 3 and 5 feet tall. These graceful birds are characterised by their long necks and legs, with pink plumage that varies in intensity from one individual to another.

Flamingos are gregarious wading birds, which means they are social and often gather in groups. They are filter feeders, straining their food from the water with their specially adapted beaks. Flamingos feed on shellfish and algae, using their unique beaks to separate mud and silt from their food.

The presence of flamingos in Salzburg adds to the diverse avifauna of Austria, which includes a recorded total of 458 bird species as of July 2023, according to the Avifaunistic Commission of BirdLife Austria (Avifaunistische Kommission, AFK).

There are 458 bird species in Austria

Austria is home to a diverse range of bird species, boasting a total of 458 species recorded as of July 2023, according to the Avifaunistic Commission of BirdLife Austria (AFK). This impressive number includes both native and introduced species, showcasing the country's rich avian ecology.

Among the 458 bird species, one notable mention is the flamingo. While flamingos are typically associated with more tropical climates, there have been sightings of these graceful birds in Austria, specifically in Salzburg. These reports and images provide a unique attraction for birdwatchers and nature enthusiasts.

The flamingo species spotted in Austria is known as the Greater Flamingo or Phoenicopterus roseus. These tall, pink birds are a stunning sight, usually standing at 3 to 5 feet in height. They are gregarious wading birds, known for their unique feeding habits and distinctive beak structure.

The presence of flamingos in Austria, particularly in the foothills of the Northeastern Alps, may be attributed to a variety of factors. One possible explanation is that these flamingos are feral or escaped zoo birds that have established a presence in the region. However, further research and observation are needed to fully understand the extent and reasons for their occurrence in this area.

Beyond flamingos, Austria's bird species encompass a wide range of families, including ducks, geese, waterfowl, cranes, eagles, and owls, to name a few. This diversity highlights the country's ecological importance and the variety of habitats it offers for these feathered creatures.

Flamingos are gregarious wading birds

Flamingos have slender legs, long, graceful necks, large wings, and short tails. They are part of the family Phoenicopteridae, which is the only extant family in the order Phoenicopteriformes. They are sometimes classified in the order Ciconiiformes (herons and storks) but also show similarities to anseriforms (ducks and geese), charadriiforms (shorebirds), and pelecaniforms (pelicans and cormorants).

Flamingos are filter feeders, consuming shellfish and algae. Their oddly shaped beaks are specially adapted to separate mud and silt from their food and are used upside down. They also have webbed feet that aid with swimming, and they may stamp their feet in the mud to stir up food from the bottom.

The pink or reddish colour of flamingos comes from carotenoids in their diet of animal and plant plankton. Well-fed, healthy flamingos have more vibrant colouring and are therefore more desirable mates.

Flamingos are considered very noisy birds, with their vocalisations ranging from grunting or growling to nasal honking. These vocalisations play an important role in parent-chick recognition, ritualised displays, and keeping large flocks together.

Before breeding, flamingo colonies split into breeding groups of about 15 to 50 birds. Both males and females in these groups perform synchronised ritual displays, such as stretching their necks upwards and uttering calls while head-flagging and flapping their wings.

Flamingos form strong pair bonds, although in larger colonies, they sometimes change mates due to the availability of more choices. They establish and defend nesting territories, with both the male and female contributing to building, protecting, and feeding their young.

They are 3 to 5 feet tall

Flamingos are tall birds, typically growing to heights of between 3 and 5 feet (91 to 152 cm). The greater flamingo is the tallest species, reaching heights of 47 to 59 inches (120 to 150 cm) and weighing up to 7.7 lbs (3.5 kg). They are found in parts of Africa, Southern Europe, and Southwestern Asia.

The shortest species of flamingo is the lesser flamingo, which stands at a height of 32 inches (80 cm) and weighs around 5.5 lbs (2.5 kg). These flamingos are found in Africa, the Great Rift Valley, and Northwest India.

The height of a flamingo can vary depending on its sex, with males typically being slightly taller than females. However, the difference is usually not significant enough to determine the sex of a flamingo based on height alone.

Flamingos are wading birds, known for their long legs and necks. Their legs are longer than their bodies, measuring between 31.5 and 49 inches (80 to 125 cm). They have three forward-pointing toes and a hallux (hind toe), which aid in swimming and stirring up food.

They feed on shellfish and algae

Flamingos are known to feed on shellfish and algae. Their diet also includes small crustaceans like shrimp, prawns, crabs, crayfish, and molluscs, as well as small fish and insects. The shape of a flamingo's bill determines its diet. Those with deep-keeled bills, such as the Lesser, James', and Andean flamingos, primarily feed on algae and diatoms. On the other hand, flamingos with shallow-keeled bills, including the Greater, Caribbean, and Chilean flamingos, tend to eat more meat in the form of insects, aquatic invertebrates, and small fish.

Algae play a crucial role in the distinctive pink or reddish coloration of flamingos. Their diet, rich in alpha and beta carotenoid pigments, particularly canthaxanthin, imparts this unique hue to their feathers, legs, and facial features. The carotenoids in algae and certain invertebrates that flamingos consume are responsible for this pigmentation. The intensity of the pink colouration varies among flamingos, with those consuming larger amounts of algae tending to exhibit darker pink plumage.

The feeding behaviour of flamingos is quite distinctive. Prior to feeding, they often stomp their feet on the lake or lagoon bed to stir up mud and sediment, thereby releasing algae and other food sources. Flamingos are filter feeders, and their unique jaw structure enables them to feed with their heads upside down, facing backward towards their bodies. Their downward-curved bill, particularly the stronger lower bill, is well-adapted for this feeding style. Flamingos pump water through their bills, aided by a piston-like tongue, to filter out their food. The water is passed back out of the bill, leaving the captured food to be consumed.

The slight differences in diet and feeding habits among flamingo species help prevent competition among them, even when they share feeding grounds. For example, the Lesser flamingos, with their deep-keeled bills, have a daily food requirement of about 60 grams of dry weight, which they filter from the water at an incredibly fast rate of 20 times per second. In contrast, Caribbean flamingos, with shallow-keeled bills, have a slower filtration rate of 4 to 5 times per second and consume larger quantities of food, approximately 270 grams of dry weight per day.
