Colorado's diverse landscapes, from high alpine meadows to lush river valleys, provide habitat for several species of stunning blue birds. Spotting these vibrant avian jewels can be a highlight of any nature walk or birdwatching expedition. This guide will delve into the common blue bird species found in Colorado, their habitats, and interesting facts to help you on your next birdwatching adventure.
What are the different types of blue birds in Colorado?
Colorado is fortunate to host several species exhibiting various shades of blue. The most commonly sighted are:
-
Mountain Bluebird ( Sialia currucoides): Known for their brilliant, almost electric blue backs and wings, males are a showstopper. Females have a more subdued, brownish-grey coloring on their backs and wings, but still boast a charming blue wash. They are found across the state, often at higher elevations.
-
Western Bluebird (Sialia mexicana): This species showcases a rich, rusty-red breast, contrasting beautifully with its deep blue back and wings. Males display brighter coloration than females. They favor lower elevations and open woodlands.
These two are the most likely blue birds you’ll encounter. While other species might migrate through or have a very small presence, these are the stars of the Colorado bluebird show.
Where can I find blue birds in Colorado?
The location you're most likely to spot a bluebird will depend on the species.
-
Mountain Bluebirds: These adaptable birds can be found across Colorado's varied elevations, from mountain meadows and open forests to even suburban areas with open spaces. Look for them perched on fence posts, telephone wires, or rocks, scanning the ground for insects.
-
Western Bluebirds: These birds prefer lower-elevation habitats, including open woodlands, canyons, and orchards. They are more commonly found in the western and central parts of the state.
What is the best time of year to see blue birds in Colorado?
Bluebirds are present in Colorado year-round, but sighting frequency varies depending on the species and time of year.
-
Breeding Season (Spring and Summer): This is generally the best time to spot bluebirds as they are actively nesting and defending their territories. You'll have a higher chance of observing them near nest boxes or suitable nesting cavities.
-
Migration (Fall and Spring): While some bluebirds are year-round residents, others will migrate, impacting local populations. Fall and spring migrations can offer exciting viewing opportunities, but sightings might be more sporadic.
What do blue birds eat?
Bluebirds are insectivores, primarily feeding on insects. Their diet also includes berries and other fruits, especially during the winter months when insects are less abundant. Their hunting strategy often involves perching and scanning the ground before darting down to catch their prey.
Do blue birds build nests?
Yes, both Mountain and Western Bluebirds build nests. They typically choose cavities in trees, cliffs, or utilize nest boxes provided by humans. The nest itself is a simple cup-shaped structure made of grasses, twigs, and other soft materials.
How can I attract blue birds to my yard?
Attracting bluebirds requires providing the right habitat and resources.
-
Nest boxes: Installing well-placed nest boxes is highly effective. The design and placement of these boxes are crucial for attracting these birds.
-
Open space: Maintain an open area around your yard, providing ample space for foraging. Avoid excessive shrubbery that might hinder their hunting abilities.
-
Berry bushes: Planting berry bushes provides a supplementary food source, particularly during winter months when insects are scarce.
-
Water source: A birdbath or other water source will also attract them.
By following these tips, you can increase your chances of having these beautiful birds grace your backyard.
Are blue birds endangered in Colorado?
Neither the Mountain Bluebird nor the Western Bluebird are currently listed as endangered or threatened in Colorado. However, habitat loss and changes in insect populations can impact their numbers.
By understanding the habitat preferences and behaviors of Colorado's blue birds, you'll be well-equipped to enjoy these vibrant additions to our state's wildlife. Happy birdwatching!
