Blue Jay vs Cardinal: A Brief Overview

The blue jay and the cardinal are both members of the avian family, but they belong to different genera. The blue jay (Cyanocitta cristata) is part of the Corvidae family, while the cardinal (Cardinalis cardinalis) belongs to the Cardinalidae family. Let’s explore these two species in detail to understand their unique features and characteristics.

Physical Characteristics

Size and Appearance

The blue jay is a medium-sized bird, measuring approximately 9 to 12 inches in length. It has a robust body with a prominent crest on its head. The plumage of a blue jay primarily consists of blue feathers on the upper body, white feathers on the belly, and black markings on its wings and tail. Additionally, blue jays have striking blue eyes.

Female cardinals have a more subdued appearance, with a mixture of gray, brown, and red feathers. Both male and female cardinals have distinctive crests on their heads.


Blue jays get their name from their predominant blue color. The shade of blue can vary slightly among individuals, with some displaying a brighter blue hue than others. The white underparts create a striking contrast against the blue feathers. Blue jays also have black bars on their wings and tail feathers.

Cardinals are renowned for their bright red plumage. Male cardinals sport vibrant red feathers, which help them attract mates and defend their territories. Female cardinals, on the other hand, have a more muted coloration to provide better camouflage when nesting.


The beak of a blue jay is robust and slightly curved. It is well-suited for cracking open nuts and acorns, which form a significant part of their diet. The beak is black in color and allows blue jays to forage efficiently.

Cardinals have a distinctive cone-shaped beak. The beak is orange-red in males and grayish in females. The shape of the beak enables cardinals to feed on a variety of seeds and fruits.

Reproduction and Nesting

Blue Jay Reproduction and Nesting

Blue jays typically mate for life and form monogamous pairs. They build their nests in the forks of trees or on horizontal branches. The nest is constructed using twigs, grass, and other plant materials, and it provides a secure place for incubating eggs.

Female blue jays lay a clutch of 2 to 7 eggs, which are incubated by both parents for approximately 17 to 18 days. After hatching, the chicks are cared for by both parents, who bring them food until they are ready to fledge.

Cardinal Reproduction and Nesting

Cardinals also mate for life and establish breeding territories. The male cardinal sings to attract a mate and defend his territory from other males. Once a pair forms, they build a cup-shaped nest using twigs, leaves, and grass. The nest is usually situated in dense vegetation, providing protection from predators.

Female cardinals lay a clutch of 2 to 5 eggs, which are incubated by the female for about 11 to 13 days. Both parents participate in feeding the chicks until they are ready to leave the nest, which typically occurs after 9 to 11 days.
