Alpine Chough

Informazioni

The Alpine Chough is a medium-sized passerine bird, a member of the crow family, characterized by its glossy black plumage, bright yellow bill, and red legs. It is highly adapted to high-altitude environments, often seen soaring effortlessly in mountainous regions.

75-85 cm

Peso

190-250 g

Up to 15-20 years in the wild

Dieta

Omnivore, primarily insects and other invertebrates in summer, supplemented by berries, seeds, and human scraps in winter.

Caratteristiche fisiche

Piumaggio

Adults have entirely glossy black plumage with a metallic sheen, particularly noticeable in good light. The feathers are dense and well-insulated for cold environments.

Forma del becco

Slender, slightly downcurved, and bright yellow. The tip can sometimes appear darker.

Colore degli occhi

Dark brown.

Colore delle zampe

Bright coral-red.

Caratteristiche distintive

The combination of glossy black plumage, bright yellow bill, and red legs is unique among high-altitude corvids. Its agile, buoyant flight is also a key characteristic.

Aspetto giovanile

Juveniles are duller black than adults, with a less glossy plumage. Their bill is yellowish-grey or dull yellow, and their legs are brownish-red, gradually acquiring the adult's bright coloration over their first year.

Cambiamenti stagionali

No significant seasonal plumage changes. The intensity of the bill and leg coloration may vary slightly with age and health, but not seasonally.

Dimorfismo sessuale

Males and females are monomorphic, meaning they are visually identical in plumage, size, and bill/leg coloration.

Come identificare

1. 1

   Plumage

   Look for entirely glossy black plumage. The sheen is often visible in sunlight.

2. 2

   Bill Color

   The bright yellow bill is a key identifier. Note its slender, slightly downcurved shape.

3. 3

   Leg Color

   Bright coral-red legs are distinctive. This color is consistent in adults.

4. 4

   Flight Style

   Observe its agile, buoyant, and acrobatic flight, often soaring effortlessly on mountain updrafts. It appears to 'dance' in the air.

5. 5

   Vocalizations

   Listen for its characteristic high-pitched, ringing 'preep' or 'treee-up' call, distinct from other corvids.

6. 6

   Habitat

   Its presence in high-altitude, rocky mountain environments is a strong indicator.

Habitat e areale

Biomi

Alpine and subalpine zones, high mountains, rocky cliffs, and pastures.

Areale geografico

Found across the high mountain ranges of Eurasia and North Africa, including the Pyrenees, Alps, Carpathians, Balkans, Caucasus, Himalayas, and Atlas Mountains.

Fascia altitudinale

Typically breeds between 1,200 and 3,900 meters (4,000-13,000 ft), but can forage up to 8,000 meters (26,000 ft) and descend to lower valleys in winter, especially in harsh weather.

Ambienti preferiti

Steep rocky slopes, cliffs, scree fields, high-altitude meadows, ski resorts, and mountain huts where food sources are available.

Comportamento

Periodo di attività

Diurnal.

Abitudini alimentari

Highly opportunistic. In summer, it forages for insects (beetles, grasshoppers, caterpillars) and other invertebrates on alpine meadows and snowfields. In autumn and winter, its diet shifts to berries, seeds, and human food scraps around tourist areas. It often probes in snow and crevices for food.

Comportamento sociale

Highly social, typically found in flocks of varying sizes, especially outside the breeding season. Flocks can number in the hundreds, particularly at communal roosts or feeding sites. They are often seen interacting with other corvids, especially the Red-billed Chough.

Tipo di volo

Extremely agile and acrobatic flier, often seen soaring and diving on updrafts near cliffs. Its flight is buoyant and graceful, with deep, flexible wingbeats. It can hover and maneuver expertly in strong winds.

Migrazione

Mostly resident, but performs altitudinal migrations, moving to lower elevations during severe winter weather or to exploit food sources. Some populations may undertake short-distance movements.

Territorialità

Breeding pairs defend a small territory around the nest site, but outside the breeding season, they are highly gregarious and non-territorial.

Riproduzione

Stagione riproduttiva

Typically from April to June, varying with altitude and geographic location.

Abitudini di nidificazione

Monogamous. Nests are built in sheltered crevices, caves, or ledges on steep cliffs, often in inaccessible locations. The nest is a bulky structure of sticks, roots, and plant stems, lined with hair, wool, and grass.

Dimensione della covata

3-6 eggs.

Descrizione dell'uovo

3-6 eggs, typically 4-5. Eggs are glossy, whitish or pale buff, heavily marked with brown, grey, and olive spots and blotches, often concentrated at the broad end.

Periodo di incubazione

18-21 days, primarily by the female.

Periodo di involo

29-31 days. Young are fed by both parents.

Cure parentali

Both parents participate in feeding the young. After fledging, juveniles remain dependent on parents for several weeks and join family groups or larger flocks.

Dove trovarlo

Consigli sul campo

1. Look Up. Spend time scanning the skies above mountain peaks and cliffs, as they are often seen soaring.
2. Listen Carefully. Their distinctive calls are often heard before the bird is seen, especially in windy conditions.
3. Visit High-Altitude Tourist Spots. Areas with cable cars, mountain restaurants, or hiking trails at high elevations often attract them due to food availability.
4. Observe Flocks. They are highly social; spotting one often means others are nearby. Watch their interactions.
5. Check Snowfields. In summer, they often forage on snowfields for insects that have been blown up by winds.

Curiosità

• The Alpine Chough holds the record for the highest-altitude bird sighting, observed at 8,200 meters (26,900 ft) on Mount Everest.
• They are incredibly agile fliers, capable of performing complex aerial maneuvers in strong mountain winds, seemingly for play.
• Alpine Choughs are known to cache food, especially in winter, hiding items in crevices or under rocks for later consumption.
• They often associate with humans in mountain environments, becoming quite tame around ski resorts and mountain huts, readily accepting food.
