21 Blue Colored Birds In North America (And Why They Are NOT Actually Blue!)

Mountain Bluebird

Have you seen a beautifully blue-colored bird and wondered what it is? But did you know this bird is tricking you and it is just an illusion?

There are NO BLUE COLORED BIRDS in the world it is just a neat trick of the light.

If you just want to ID some birds that look blue then I’ve got what you need too. There are lots of birds other than Blue Jays or the rest of the Jay family that are blue. Bluebirds are the most familiar but there are also warblers, grosbeaks and buntings that are blue in North America.

The sky is blue because the air molecules scatter the light and cause it to change wavelength so you ‘see’ the sky as blue and blue feathers work in a similar way. The tiny air pockets in the feathers scatter the light and most of the light passes through except blue light which is reflected instead so you see blue.

If you see a Blue Jay feather from the back it will not look blue and is actually brown. It is a structural color and not a pigment color. So there you go mind blown!

So check them out.

21 Blue Colored Birds:

1. Eastern Bluebird

Eastern bluebird

Eastern Bluebirds are small thrushes with big, rounded heads, large eyes, and big bellies.

The males are deep blue on the back and a reddish color underneath. Females are grayer above with some blue in the wings and tail and a less vivid orange-brown breast.

Attract Eastern Bluebirds to your backyard by offering mealworms and nest boxes if your yard is pretty open and spacious.

2. Western Bluebird

western bluebird

Western Bluebirds are blue birds with orange chests. They are very social small stocky thrushes that are shiny blue on the back and rust-orange on the breast and across the upper back in the males.

Western Bluebirds are found in western US states and do not usually migrate. However, some birds in the far northwest may migrate south or to lower elevations.

You can find Western Bluebirds in woodlands rather than open areas, and they are readily found in areas that have dead trees, such as burned forests and logged areas.

I Summer Western Bluebirds cat insects such as caterpillars, beetles, and ants, as well as spiders and snails or other ground-dwelling insects. In winter, Western Bluebirds eat fruit such as elderberry, grapes, mistletoe, raspberries, blackberries, sumac, and juniper.

California Scrub-Jay sounds: Their call is high-pitched and repetitive. They also sing a courtship song of soft whistles.

Richard E. Webster, XC662075. Accessible at www.xeno-canto.org/662075.

Nests of California Scrub-Jay are usually hidden in oak trees and can take up to 10 days to construct the nest made of twigs and a soft lining. They lay 1 – 5 eggs, and the eggs take around 17 – 19 days to hatch.

Attract California Scrub-Jays to your backyard with sunflower seeds and peanuts in your feeders.

Fun fact: California Scrub-Jay will screech over the body of a dead jay and invite others to do the same, and this can last up to half an hour, according to the University of California – Davis

8. Florida Scrub-Jay

Florida Scrub-Jays are blue, with gray bellies, backs, and foreheads. They have long blue tails and do not have a crest on their heads. Males and females look the same, but juveniles are grayer and have gray heads.

Florida Scrub-Jay sounds: They make quite harsh calls and spend a lot of time calling to each other.

Bruce Lagerquist, XC371888. Accessible at www.xeno-canto.org/371888.

Nests of Florida Scrub-Jays are usually in oak trees or shrubs, and they form cooperative flocks, which include young from the previous year. These flocks help protect from predators and feed their young. The offspring then find a territory of their own.

Fun fact: Florida Scrub-Jays break acorns apart by holding them in their feet and using their bills to hammer on the acorn until it breaks open.

9. Island Scrub Jay

You can find Great Blue Herons in many wetland environments. They can be present in fresh and saltwater marshes, mangrove swamps, flooded marshes, lake edges, or shorelines.

Great Blue Herons’ main diet consists of fish, frogs, salamanders, shrimps, crabs, dragonflies, grasshoppers, and other aquatic insects.

They capture their prey when wading or standing in water. They may also hover over water, dive into the water, jump feet-first from perches, or float on the water’s surface. 

Great Blue Heron Call:

Nests of Great Blue Herons are found in colonies, high up in trees close to water. The nests are made with twigs and sticks lined with softer material.

Since Great Blue Herons reuse their nests, they may repair and add more to the nests over time, growing them in size.

The female then lays two to seven eggs. Both parents take turns incubating the eggs for around four weeks. 

Fun Fact: Great Blue Herons defend their feeding territory with dramatic wing outstretched displays, with their heads thrown back.
