Bird Profile: Blue Bird
1. Bird Name
The bird under discussion is commonly known as the Blue Bird. Its scientific name is Sialia sialis.
2. Appearance
Blue Birds have a striking coloration that catches the eye. They possess a brilliant blue hue on their back, wings, and head. Their bellies are reddish-orange, contrasting well with the top. The Blue Bird has a thin, short beak perfect for its insectivorous diet, and its eyes are dark and sharp. Females are less brightly colored than males and often display more grey or dull blue shades. Juveniles have a spotted pattern on their back and chest.
3. Size
Blue Birds are small creatures, averaging at about 16-20 cm (6.3-7.9 inches) in length. Their wingspan typically reaches up to 25-32 cm (9.8-12.6 inches). Blue Birds weigh between 27-34 grams (0.95-1.2 ounces).
4. Habitat & Distribution
Blue Birds are native to North America and are widespread across the continent in appropriate habitats. They can be found stretching from Canada, across the United States, and into Mexico. They prefer open country with scattered trees for nesting, such as farmland or open woodland, and are notably absent from deep forests.
5. Interesting Facts
– Blue Birds perform an intriguing aerobatic display during courtship involving flying patterns that mimic a roller coaster trajectory.
– Contrary to their name, not all blue birds are blue. Females tend to have more subtle coloration than males.
– Blue Birds are considered symbols of happiness in many cultures
6. Diet
Blue Birds primarily eat small insects and berries, although their diet can expand to include earthworms, snails, and other small invertebrates when insects are scarce.
7. Behavior & Sounds
Nest in cavities and birdhouses; fly in a distinct straight-line, making foraging flights from perch. Their songs often sound like a soft, melodious warble or whistle – “tu-wheet-tudu” with the second note higher pitched.
8. Conservation Status
The Eastern Bluebird was severely impacted in the mid-20th century due to aggressive species taking over their nesting sites and pesticide exposure. However, with conservation efforts, including the introduction of birdhouses, they have made a remarkable recovery and are now classified as ‘Least Concern’ by the IUCN.
9. Lifespan
Typically, a Blue Bird lives on average 6-10 years in the wild, but they can live up to 10 years in captivity. However, the record of a Blue Bird longevity is 10 years and 5 months in the wild.
10. Additional Notes
Blue Birds are known locally as “Azulejo” in Spanish-speaking countries. They play an essential role in ecosystems as they eat many insects that could turn into pests if their numbers were not controlled. Despite being shy, they coexist relatively peacefully with humans and are beloved for their beauty and symbolism.
