Contrary to popular belief, not only are the Blue Jay and the Cardinal members of separate genera, but they are also members of distinct families, as well. In scientific terms, cardinals are members of the Cardinalidae family, which is comprised of members of the cardinal order. The blue jay is a member of the Corvidae family of birds, which is formally known as the crow family.


Blue Jays may be found in various habitats, although they are most commonly seen in and around oak trees. These species are more common around forest boundaries than they are found deep in the trees.

Cardinals may be found in various habitats, including woodland edges, grassy lawns, trees and shrubs, back gardens, and well-landscaped areas.

Cardinals build their nests in dense foliage and look for platforms to sing from that are conspicuous and relatively high in the sky.


Even though both birds are classified as songbirds, their vocalizations are quite different. The blue jay has a mellower voice and almost sounds like a whisper compared to the other birds. The Cardinal’s song sounds just like someone is whistling if you listen closely.

Singing over a longer amount of time is characteristic of the blue jay, with a single song lasting as long as 2 minutes. The song of a cardinal is short, lasting just approximately 2-3 seconds on average.

Cardinal’s song comprises a long succession of clear two-parted whistles that are periodically accelerated before culminating with a progressive treble at the end.


The food of the two birds is perhaps the most noticeable distinction between them both. Cardinals are granivorous, meaning they eat grains, seeds, and fruits.

On the other hand, Blue jays are omnivores, meaning they eat almost anything. In addition to cereals, they eat frogs, mice, and nuts, among other things. However, the most remarkable aspect is that blue jays have been observed eating the eggs of other birds, which is rather unusual.
