1. Nombre del ave
Commonly referred to as the Wigeon, this bird species has the scientific denomination of Anas penelope.
2. Aspecto
The Wigeon boasts a distinctive and colorful plumage pattern. Males have a rich, chestnut colored head adorned with a cream-colored crown and a slate-grey body. Their underwings flash a distinct white when in flight. It has a small blue-grey bill and pinkish legs. Females, on the other hand, are more nondescript with mottled brownish-grey coloration, although they have similar underwing patterns. Both sexes possess a unique, round shape balanced with a short bill and small head.
3. Tamaño
On average, Wigeons measure around 45-51 cm (18-20 inches) in length. Its wingspan generally varies from 78-86 cm (30-34 inches). The weight of an adult Wigeon usually ranges between 580-1100 grams (1.3-2.4 pounds).
4. Hábitat y distribución
Wigeons inhabit a broad range, with natural populations in North America, Europe, and Asia. They are strongly migratory and typically spend their summers in the northern parts of these continents, migrating to the south and coastal areas during winter. Their favored habitat includes wetlands, bogs, marshes, as well as lakes and estuaries.
5. Datos de interés
Wigeons exhibit an interesting feeding behavior which is known as “kleptoparasitism” – they often obtain food by stealing from other ducks. Interestingly, Wigeons are highly sociable birds, rarely seen alone. One common belief in various cultures is that the sighting of a Wigeon foretells good luck.
6. Dieta
The Wigeon has a predominantly vegetarian diet, feeding on a wide variety of plant species. They also consume some aquatic invertebrates, providing a source of protein.
7. Comportamiento y sonidos
Wigeons are well known for their distinctive whistle-like call. Males emit a high-pitched “wheeooo” whistle, while females produce a gruff and low “rawr.” Wigeons display a curious behavior of spending less time diving underwater for food and more time grazing on land compared to other ducks.
8. Estado de conservación
Currently, the Wigeon is categorized as “Least Concern” by the IUCN Red List, owing to their wide distribution and large populations. However, factors such as habitat loss and hunting pose potential threats.
9. Vida útil
In the wild, a Wigeon typically enjoys a life span of 9-12 years, although they can live up to 20-22 years in captivity with optimal care.
10. Notas adicionales
In Russia, Wigeons are termed “Svistun,” which translates to the whistler, referencing their unique whistle-like call. In terms of their role within ecosystems, they serve as critical agents of seed dispersal encouraging plant biodiversity. Wigeons are typically shy around humans, but they are occasionally seen in urban parks and other cultivated areas where there is abundant food.
