Comparing Male and Female Northern Cardinal

Key Differences Between Male and Female Northern Cardinals 

Male and female northern cardinals have some differences in their size, appearance as well as behaviors, and these differences, especially the size and physical differences, can help us tell them apart. Let’s take a more in-depth look. 

Male Vs Female Northern Cardinal: Size

Male and female northern cardinals actually have a slight difference in size even though they look exactly the same. The male northern cardinal measures about 8.7-9.25 inches in length while also weighing between 1.5-1.7 ounces. The female northern cardinal, on the other hand, has a length of 8.2-8 5 inches and weighs 1.4-1.5 ounces. These figures show that on average, the male northern cardinal is larger than the female. 

Male Vs Female Northern Cardinal: Appearance

The male northern cardinal has a black face, red plumage, red wings, red tail, red crest, and a red and black throat. Basically, male northern cardinals are predominantly red and that’s the first thing most people would notice about them.  Female northern cardinals, on the other hand, have a pale grey face, gentle red crests, pale brown plumage, yellow-brown throat, and pale-red wings. In other words, they are not nearly as red as their male counterparts and their predominantly pale brown or grey color is a simple hack to tell them apart. 

Male Vs Female Northern Cardinal: Diet

As one would expect, male and female northern cardinals are omnivores. They have the same diet comprising fruits, seeds, nuts, and insects. As a matter of fact, males are often in charge of collecting food as the females would often sing out to them gently when they are starving.

Male Vs Female Northern Cardinals: Nest Contributions 

We mentioned earlier that female northern cardinals often sing out to their male counterparts when they are hungry. In the same vein, females are in charge of building nests while males would go out and look for nesting materials. Nest building takes about 2-3 weeks depending on the availability of nesting materials.  Females would also incubate their eggs in the nests until they have hatched. Talk about division of labor. 

Male Vs Female Northern Cardinals: Incubation

As is the case with most animals, male and female northern cardinals often get together and mate. After mating, the females produce eggs which they will spend time incubating in their nest. Incubation often lasts for 11-13 days. During these periods, the males take on the responsibility of supplying food and making sure the females are well fed. The males would also sometimes take charge of incubation for short periods. Everything about the process screams equality, romance, and reasonably fair division of labor. Wouldn’t you agree?

Male Vs Female Northern Cardinals: Singing Patterns

Male and female northern cardinals exhibit different behaviors through their singing patterns. Males would frequently sing out loud in an aggressive manner and they often do this to preserve and defend their territories. They may also sing as a way of charming females and if they succeed, they would often stay hooked to that particular female for life, barring a divorce. Also, males sing a lot more frequently during breeding seasons. Female birds, on the other hand, have gentle singing patterns and they do not sing as often as their male counterparts do. When they sing, they are intentional about it and many times, it is their way of telling the males that they are hungry and need food.  Northern cardinals, irrespective of their sexes, may also sing to warn others of impending predatory threats. Predators include eagles, owls, falcons, snakes, chipmunks, and squirrels.   We must mention that singing patterns differ among northern cardinal individuals and can be influenced by geolocation. 

Male Vs Female Northern Cardinals: Lifespan

Both male and female northern cardinals live for about 3 years when in the wild. When held captive, they can live beyond 3 years and as long as 28 years. It might interest you to know that male and female northern cardinals who already have mating partners would often remarry after the death of their partners.
