The rock ptarmigan

Rock ptarmigan

The rock ptarmigan (Lagopus muta) is a bird belonging to the Tetraonidae family, inhabiting the Arctic and subarctic regions of Eurasia and North America, as well as some isolated mountainous areas, such as the Alps, the Pyrenees, Scotland, and Japan.

In Italy, the rock ptarmigan is found in the Alpine arc, particularly in the regions of Veneto, Trentino-Alto Adige, and Friuli-Venezia Giulia, where it inhabits the ideal habitat above the tree line, between 1800 and 2800 meters in altitude, in the Dolomites.
The white ptarmigan is one of the marvelous specimens of the alpine fauna in our country, thanks to its unmistakable perfect camouflage. This bird prefers to inhabit high altitudes, living above 1800 meters and nesting at altitudes of up to 2800 meters.

Characteristics

It is a medium-sized bird, reaching a length of up to 40 cm and weighing around 500 grams. It has a short, robust beak, short, feathered legs, and a black tail with outer white feathers. The most distinctive feature of the rock ptarmigan is its ability to change the color of its plumage according to the seasons, allowing it to better blend in with the surrounding environment. In winter, when the ground is covered with snow, its plumage is pure white, except for the tail and a black band between the eye and the beak, which is only present in males.

In summer, on the other hand, the plumage becomes gray or brown, with various shades depending on the sex and subspecies. Males have a speckled black chest and upper body, while females have a more varied plumage, with streaks and spots of red, yellow, and black.

Rock ptarmigan’s call

The rock ptarmigan produces guttural sounds, especially during the breeding season. The call and song, a raucous “kroo rr kkkk,” are unmistakable. The rock ptarmigan’s vocalizations are most commonly heard during April, May, and June, particularly during the early hours of daylight.

Behavior of the rock ptarmigan

The rock ptarmigan is a sedentary and territorial bird forming small families or groups. It primarily feeds on alpine plants’ buds, leaves, flowers, seeds, and berries but also consumes insects, worms, and snails. When food is scarcer in winter, the ptarmigan digs tunnels under the snow to reach hidden plants or feeds on conifer needles and lichens.

The white ptarmigan is a monogamous bird that nests in small ground hollows, rocks, or bushes between May and June. The female lays 6 to 12 eggs, which she incubates for about three weeks, while the male guards the territory and defends the brood from predators. The chicks are precocial, meaning they can follow the mother and feed themselves shortly after hatching. They are covered with a brown or gray down, with dark spots and streaks, providing camouflage against the ground. After about two months, the young birds become independent and develop adult plumage.

Vulnerable species

Once considered a well-conserved species, Italy’s rock ptarmigan is now endangered. The Red List of Threatened Species categorizes it as a “Vulnerable” species.

To preserve the rock ptarmigan and its ecosystem, it is crucial to protect natural areas, including the National Park of the Belluno Dolomites, the Natural Park of the Ampezzo Dolomites, the Natural Park Fanes-Sennes-Braies, the Natural Park Paneveggio-Pale di San Martino, the Natural Park Adamello-Brenta, and other regional and provincial parks where the rock ptarmigan can find its ideal habitat and reproduce safely.

Additionally, it is essential to raise awareness among the local population and tourists about respecting this alpine bird, which represents the Dolomites’ natural and cultural heritage.

Curio and legends
