sparrows

1. Nombre del ave
English name: Sparrow
Scientific (Latin) name: Passeridae

2. Aspecto
Primarily known for their subtle professionalism in terms of colors and patterns, sparrows don an earthy brown tint highlighted with darker streaks. Their feathers usually range from white to gray and from rich brown to black. Another distinctive marking of sparrows is their broad, chunky beak designed to crush seeds, their main food. Typically, the eyes of sparrows are brown with a circular black pupil. Male and female sparrows exhibit sexual dimorphism, with males showcasing more vibrant coloration and patterns as compared to females.

3. Tamaño
The average length lies between 5 to 6 inches (12.7 to 15.24 cm). The wingspan ranges from 6 to 9 inches. A typical sparrow weighs around 0.85 to 1.4 oz (24 to 40g).

4. Hábitat y distribución
Sparrows are distributed all across the globe, especially in North America, Europe, Asia, and Africa. They thrive in both rural and urban settings, but prefer human habitation, agricultural fields, or grasslands rather than dense forests or deserts.

5. Datos de interés
One of the most interesting facts about sparrows is their monogamous nature. They bond with a single mate for a season, a few seasons, or possibly for a lifetime. Additionally, sparrows are among the very few species of birds that indulge in dust bathing. They are culturally significant in many cultures, often symbolizing peace or prosperity.

6. Dieta
Sparrows are basically omnivores. They commonly feed on seeds and grains but are also known to consume small insects and fruits occasionally.

7. Comportamiento y sonidos
The behavior of sparrows varies across species. They can often be seen hopping on the ground searching for food. Sparrows are sociable birds that prefer living in colonies. The call of a sparrow is quite unique – a series of chirp chirp or cheep cheep sounds, often used to draw attention or express alarm.

8. Estado de conservación
While some types of sparrows are of least concern according to the IUCN Red List, the species as a whole is believed to be under threat, mainly due to habitat changes prompted by human activities. Urbanization and loss of traditional farming practices are key points of concern.

9. Vida útil
The average lifespan of sparrows is generally short, with most reaching only 4-5 years in the wild, although some have been recorded to live up to 13 years.

10. Notas adicionales
Many cultures celebrate sparrows in their folklore or proverbs. In Japan, for instance, sparrows symbolize loyalty because of their monogamous nature. Humans and sparrows share a longstanding relationship, with the birds often relying on human habitation for food and nesting. Furthermore, sparrows also help in controlling pest populations by feeding on insects, consequently aiding in maintaining the balance of the ecosystem.
