Range

The North American cardinal is a very popular bird in its own family, the Cardinalidae. It is also referred to colloquially as simply the Northern Cardinal.

It is found in southern Canada, from southern Minnesota to northern Texas to Arkansas, westward to Mexico, Belize, Guatemala, and Honduras. Furthermore, it is found in nearly all major parts of the continent.

Male & Female

Male birds are usually larger than female ones, and male birds can grow to be anywhere from 8-9″ inches in length. In their early months of life, male cardinals are not too noticeable, because they are mostly nocturnal. During the day, they spend time feeding on berries, seeds, nuts, nectar, carrion, worms, and other insects.

Nesting

Cardinals lay eggs that are shaped like hollow spheres. They are attached to the egg case by a “crimp” that is called a “sperme.” When the female redbird emerges from her nest, she lays an eggshell on the egg case.

This eggshell protects the egg and the inside from harmful elements, as well as protecting the baby. Once the baby bird emerges from its eggshell, it takes a few days for it to be born and for its feet claws to emerge from its skin.

Its body is soft, and fleshy when it emerges, but hardens as it matures. The male cardinals are usually large and powerful. Males feed the female redbird, which feeds them.

The male and female redbirds breed for several years before they separate. Then the male goes off to mate with another female. Eventually, the female will return to the nest, lay the eggs, which will hatch into the next generation.

Many people believe that the only difference between a male and female northern cardinal is their color. However, they are actually very different creatures with a number of notable differences.

The average length of a male northern cardinal is 8 to 9.0 inches with an average weight of 1.5 to 2 ounces, and have a wide wingspan which measures 10 to 12 inches.

Females on the other hand are typically 7-8 inches long with an average weight of 0.8 ounces.

Flight Speed

The cardinals flight is long, swift, and steady, making it one of the fastest birds on the earth. It is known to fly at up to 30 miles per hour, and it can be observed flying at night and during the daytime.

Furthermore, it has a very acute hearing sense, and it can hear the clicking of its beaks on the branches, its wings beating against the wind, and the passing of insects.

Characteristics

The Northern Cardinal is a well-known bird that sings loudly and often. The cardinal’s song typically lasts for 2 to 3 seconds, with many repeated phrases.

Cardinals can sing during the day or night, but it is more common at dawn and dusk. The male and female will sometimes sing together in courtship rituals.

Male cardinals are very territorial when it comes to protecting their nests and young. While the female incubates the eggs, it is the male’s duty to protect.

Male cardinals have been observed on many occasions attacking other birds such as hawks or even humans that approach their nest too closely.

They will use vocalizations and physical contact in order to scare off these intruders from a distance before they get too close to his precious offspring’s nest site.

Life Expectancy

The cardinal has a lifespan of around 3-4 years in the wild, though it is possible to get them to live for twenty years in captivity.

If you are going to breed a pair of cardinal birds, be sure to have them bred under the strictest conditions so that the females will only have the best conditions to produce the strongest offspring.

The male cardinal has a tendency to roam from one place to another and mate with many females. This is where the male can have trouble making a decision regarding which female it prefers to mate with and therefore be less likely to produce the strongest offspring.
