Are Blue Cardinals Real?

Some passionate birdwatchers have reported several theories and truths about blue cardinals. What are they?

Birdwatchers have reported the fact that blue cardinals do not exist. The name, color, or size of blue cardinals is a myth. However, the reasoning behind this misunderstanding is that people confuse other birds as blue cardinals. This is because of the similarities of those birds with the cardinal species.

The confusion may occur due to different reasons, some of which are:

  • Similar Appearance

  • Change in color over time

  • Difference of lightning or distance


To spot and differentiate a bluebird from a cardinal, you should invest in a good telescope to see clearly.

1. Similar Appearance

Birds, in general, have many similar characteristics, whether it is in appearance or their action. This is why before determining the type of bird, you may have to read into them simply because some bird species may look so much like another bird species.


To identify the type of bird in front of you, try observing the bill and the bird's shape first. These two features differ in most birds.

2. Change In Color

Some birds, like northern cardinals, transition into different colors and may drastically change in appearance throughout various stages of their life.

A bird may look different when it is young, and the appearance or color may change when it grows older.

Fun Fact

Northern cardinals get their bright red color from a pigment called carotenoids, primarily found in red berries.

3. Difference In Lighting or Distance

Male northern cardinals are primarily found in a prominent red color, but some cardinals have tints of other shades like brown, grey, or yellow on other parts of their body.

These tints might be perceived as a different color on the bird itself from a distance or at times of varying lighting.

The color of feathers is primarily influenced by angle and light. This may make it easier for people to perceive a particular bird as a blue cardinal.

Fun Fact

Most birds have different tints of color on their feathers rather than having one single color on them.
