Cardinals are undoubtedly eye-catching members of the Cardinalidae family, encompassing three species – the well-known Northern cardinal (Cardinalis cardinalis), the Vermilion cardinal (Cardinalis phoeniceus), and the Pyrrhuloxia (Cardinalis sinuatus), also known as the Desert cardinal. While cardinals are famed for their vivid red hue, it’s important to note that only the males flaunt this fiery plumage.
Female cardinals, though not bedecked in the same bright tones, possess their own beauty, marked by distinct differences from their male counterparts. This comprehensive guide sheds light on the characteristics of female cardinals.
Female cardinals exhibit disparities from males across all three cardinal species. Male Northern and Vermilion cardinals typically showcase vibrant red coloring coupled with prominent crests. In contrast, the Desert cardinal stands apart with muted tones, featuring gray sides and a shorter crest.
A Comprehensive Guide to Female Brown Cardinals
Female cardinals, though not as brilliantly colored as their male counterparts, are captivating and unique birds that grace gardens and backyards with their presence. Here’s a complete guide to understanding and appreciating female cardinals:
Physical Characteristics and Appearance
Female cardinals are slightly smaller than males, measuring between 7 to 9 inches in length with a wingspan of 10 to 12 inches. They sport a predominantly brown and gray plumage that enables them to blend seamlessly with their surroundings. While they lack the vibrant red hue of male cardinals, their subtler coloring serves the purpose of camouflage and protection.

Diet and Feeding Habits
Female cardinals have a varied diet, including seeds, insects, berries, and fruits. They’re particularly fond of suet, a type of bird feed that can attract a diverse range of bird species. Offering a variety of food sources is essential for their health and activity.
Lifespan and Social Behavior
In the wild, female cardinals can live up to 10 years, while those in captivity may reach up to 20 years. They are monogamous birds that often spend their lives in pairs or small flocks. Their social nature adds vibrancy to outdoor spaces.
Nesting and Habitat
Female cardinals build their nests high in trees, typically close to the trunk. These nests are constructed using twigs, leaves, grasses, and spider webs. They create a safe haven for their eggs and chicks, emphasizing protection and shelter.
Benefits of Attracting Female Cardinals
Welcoming female cardinals to your backyard or garden can be a rewarding experience. Their social behavior and unique beauty contribute to the charm of outdoor spaces. Their presence adds color and life, making them a delightful addition for bird enthusiasts.
Distinguishing Features
Female cardinals can be identified by their smaller size, brown and gray plumage with streaks, and distinct crest of feathers on their head. Despite their less vibrant appearance, they possess their own allure and contribute to the diversity of avian life.
Color Variation and Sexual Selection
The difference in color between male and female cardinals is primarily attributed to sexual selection. Males exhibit brighter colors to attract mates, while females possess more subdued hues for camouflage and protection. This color distinction aids in mate selection and differentiating between the sexes.
Distinct Behavior and Vocalization
Female cardinals display unique behaviors compared to males. While they may be less vocal, they tend to forage closer to the ground. Understanding these behavioral differences adds depth to bird observation and appreciation.
Is it possible for a cardinal to exhibit characteristics of both genders?
There have been multiple instances where cardinals have been observed displaying a blend of male and female traits, sometimes making it challenging to discern their sex. Some of these occurrences could be attributed to leucism. Leucistic male cardinals often exhibit diminished red plumage due to a genetic mutation that hampers pigment production in animals.
Perhaps the most peculiar illustration of this phenomenon involves cardinals that seem to possess traits from both males and females, almost as if they are split down the middle between the two genders. An intriguing example highlighted by NBC News featured a cardinal with a 50/50 male/female appearance, showing male plumage on one side and female plumage on the other.
An alternative perspective on this topic is the existence of leucistic female Northern Cardinals, lacking coloration on their faces.
Scientifically, such organisms are termed bilateral gynandromorphs, denoting animals that manifest characteristics of both sexes and are effectively divided down the middle, representing both genders. The majority of gynandromorphs are hermaphrodites, meaning they possess the reproductive organs of both males and females.
Various theories attempt to explain the occurrence of cardinals displaying traits of both sexes. One hypothesis suggests that male and female embryos might fuse during development, while another proposes that eggs laid by females could carry copies of both sexual chromosomes, subsequently fertilized by male sperm. During the development of many complex organisms, symmetry is often maintained, which could explain the distribution of male traits on one side and female traits on the other.
Why are male cardinals more vibrant red than females?

Male and female cardinals display a significant visual distinction known as sexual dimorphism. This means that the appearance of males and females differs notably. Specifically, cardinals are categorized as dichromatic, indicating that males and females have dissimilar colors despite sharing a similar body shape and size.
This phenomenon of sexual dimorphism is widespread among various bird species, including mallard ducks, pheasants, peafowls, and numerous parrots and tropical birds, akin to the cardinal. In fact, subtle variations in appearance between males and females are observed in most bird species.
In the case of cardinals, the evolution of bright red plumage in males serves the purpose of attracting and competing with females during the mating process.
Their diet, rich in carotenoid pigments found in items like berries, tomatoes, and deeply pigmented fruits and vegetables such as carrots (from which “carotenoids” derive their name), contributes to this remarkable plumage. These carotenoids are metabolized by male cardinals and deposited into their feathers. Males with more intense red coloring are often associated with habitats abundant in vegetation and food resources, making them more favorable contenders for reproduction.
Through a process of selective reproduction over generations, the more vividly red males survived and passed on their traits, while less red males faced reduced reproductive success and thus declined in number. This has led to the intensification of red plumage in males over time, while females have retained their relatively consistent appearance. Although females also accumulate carotenoid pigments in their feathers, the extent is lesser and primarily focused on their underwings.
How common is the sighting of female cardinals?
The population of female cardinals is nearly equal to that of male cardinals, making the chance of encountering a female cardinal roughly comparable to encountering a male. However, female cardinals are somewhat more challenging to spot due to their lack of bright red coloration, which allows them to blend more effectively with their surroundings.
Male cardinals might stand out more due to their behaviors, movements, and vocalizations, potentially drawing more attention to themselves. Additionally, during the breeding and nesting seasons, female cardinals tend to spend more time incubating eggs or caring for chicks, rendering them less conspicuous compared to males.
Which other bird shares a resemblance with a female cardinal?
Female cardinals across all three species of true cardinals exhibit a similar appearance that can lead to confusion: Vermilion, Northern, and Pyrrhuloxia (Desert cardinals).
Certain red-colored birds like Phainopeplas, Vermilion flycatchers, Scarlet tanagers, and Summer tanagers bear resemblance to male cardinals, at least in terms of coloration. However, in some cases, the females of these species also share similarities with female cardinals.
Phainopeplas possess crests, and while the males are deep black, the females have a resemblance to female cardinals, albeit being darker and devoid of any red plumage. Scarlet tanagers present a distinct sexual dimorphism, with males displaying a rich red hue and females featuring a lighter green coloration.
Female California towhees also exhibit similarities to female cardinals in appearance, but they lack any red plumage and a characteristic head crest.
Final Thoughts on Brown Cardinals
The American cardinal, with its striking beauty and distinct characteristics, holds a special place in our natural world. Understanding the differences between male and female cardinals enhances our appreciation for these remarkable birds. Their social behaviors, nesting practices, and unique roles in the ecosystem contribute to their significance in avian diversity.
By recognizing the behavioral disparities between male and female cardinals, we can foster a deeper connection with these creatures and ensure their protection for generations to come. Through our collective efforts in conservation and habitat preservation, we can continue to enjoy the presence of these magnificent birds in our lives.
