In the vast tapestry of avian life, cardinals emerge as a symbol of vibrancy and melodious charm. While many admirers are drawn to their rich plumage and captivating songs, there’s another, more subtle aspect of their existence that’s equally enchanting – their eggs.
Unravel the mysteries of cardinal reproduction, from the color and texture of their eggs to the intricate patterns of incubation and hatching.
This guide will walk you through the delicate journey of life, as seen through the eyes of our beloved scarlet songbirds.
Quick Summary
- Appearance:
Cardinal eggs typically have a pale greenish, bluish, or grayish hue. They might also have touches of brown or lavender and may be marked with streaks, blotches, or speckles, especially on the wider end. - Size and Shape:
Cardinal eggs are oval-shaped and measure about an inch in length. They are somewhat similar in size to a large olive. - Clutch Size:
A female cardinal typically lays 2 to 5 eggs per clutch. It’s not uncommon for cardinals to have multiple broods in a single season, particularly in warmer climates. - Incubation Period:
The female cardinal is primarily responsible for incubating the eggs. The incubation period usually lasts between 11 and 13 days. During this time, the male may bring food to the nesting female or even take short turns keeping the eggs warm. - Hatching:
Once the incubation period is over, the eggs will hatch over a period of several hours to a couple of days. Cardinal chicks are altricial, meaning they are born blind, featherless, and completely dependent on their parents. - Nest Predators:
Cardinal eggs are vulnerable to a range of predators including snakes, squirrels, blue jays, and crows. Protective placement of the nest in dense shrubs or thickets can help in reducing the risk from predators. - Parental Care:
After hatching, both the male and female cardinals take turns feeding the chicks. The young cardinals are ready to leave the nest about 7 to 13 days after hatching, but they still depend on their parents for food and protection for a couple more weeks.

Number of Eggs
Nests typically contain a clutch of 2-5 cardinal eggs. This is a moderate number, allowing the parent birds to fully attend to each egg and provide the necessary care and incubation throughout the hatching process.
Laying Season
Northern Cardinals lay eggs in the cardinal nest from February to September. During this period, nature’s stage is set for the awe-inspiring display of cardinal courtship and procreation. The harmonious songs of these birds and the luscious colors of their feathers serve as a joyful reminder that new beginnings are just around the corner.
Cardinal Courtship
The Northern Cardinal courtship is a heartwarming sight to behold. These birds engage in an affectionate ritual, expressing their feelings and forming strong bonds with their partners. The male northern cardinal plays a significant role in this process, as he showers his female counterpart with nourishment and displays of devotion.
Affectionate Ritual
In the world of cardinals, courtship is a dance of love. The male cardinal approaches his chosen mate, offering her delectable treats and tokens of his affection. This demonstration of love and dedication serves to strengthen the bond between the pair, laying the foundation for a successful breeding season.
Male’s Role
The male cardinal’s role extends beyond courtship rituals. Once the female has selected her partner, the male becomes her knight in shining armor as the cardinals mate. He tirelessly forages for food, ensuring she receives the sustenance necessary for her well-being and the development of their future offspring. This captivating display of chivalry reminds us of the incredible lengths animals go to in order to protect and care for their loved ones.
Clutches per Year
Cardinals are prolific breeders, capable of producing multiple clutches per year. They can have anywhere from 2 to 5 clutches, showcasing their remarkable reproductive abilities. This allows them to maximize their chances of successfully passing on their genes and ensuring the survival of their species.
Range of Clutches
The exact number of clutches per year varies among individual cardinals and is influenced by factors such as food availability and environmental conditions. Some cardinals may only have two clutches, while others may have the opportunity to raise up to five broods. This adaptability and flexibility in their reproductive behavior contribute to their overall success as a species.
Hatching Time
After the laying season comes the enchanting period of hatching. Northern cardinal eggs require time and nurturing in order to develop into vibrant fledglings that will eventually take flight.
Incubation Period
A cardinal egg takes approximately 12-13 days to hatch. During this time, the parent birds diligently incubate the eggs, ensuring optimal conditions for the delicate lives growing inside. The anticipation and excitement during this period are palpable, as the parents eagerly await the arrival of their precious offspring.
Development of Fledglings
Once the cardinal eggs have hatched, the fledglings begin their journey of growth and discovery. Spending time nestled in the safety of the nest, they start developing their strength and independence under the watchful eyes of their doting parents.
Nest Duration
Baby cardinals typically stay in the cardinals nest for a duration of 7-13 days after the eggs hatch
before they are ready to take flight as fledglings. During this time, they grow rapidly, their feathers gradually replacing their fluffy down. This period is an essential phase in their development, allowing them to build essential skills and strength before venturing out into the world.
Independent Fledglings
Once the fledglings have gained enough strength and confidence, they leave the nest and begin their quest for independence. It is a thrilling sight to witness these young cardinals taking their first flights, their vibrant feathers carrying a sense of newfound freedom. From this moment forward, they will rely on their own abilities to navigate the world around them.
Abandonment of Cardinal Eggs
In the intricate dance of nature, cardinals, like many bird species, sometimes face circumstances that lead to the abandonment of their eggs. Understanding why this happens can shed light on the fragile balance of avian life and the factors that influence these difficult decisions.
- Predator Disturbance: If cardinals sense a consistent threat from predators like snakes, squirrels, or larger birds, they might abandon their nest to ensure their own survival, even if it means leaving the eggs behind.
- Human Interference: Frequent disturbances from humans, such as approaching the nest too often, can lead cardinals to abandon their eggs. They perceive such disturbances as threats.
- Unviable Eggs: Sometimes, the eggs might not be fertilized properly or could be damaged. In these cases, after a certain period of incubation without the eggs showing signs of life, the cardinals might abandon them.
- Extreme Weather Conditions: Harsh weather, be it excessive rain, wind, or temperature fluctuations, can make it challenging for cardinals to maintain the necessary warmth and safety for the eggs. In such cases, they might leave in search of a more conducive environment.
- Nest Instability: If the nest’s structural integrity is compromised due to factors like strong winds or poorly chosen nesting materials, cardinals might abandon the site.
What To Do If You Find Abandoned Eggs
- Do Not Touch: It’s essential to resist the urge to handle or “rescue” the eggs. There’s a chance that the parents might return.
- Contact Professionals: If you’re certain the eggs have been abandoned, contact a local wildlife rehabilitator or bird sanctuary for advice on the next steps. They have the expertise and resources to handle such situations.
- Provide a Safe Environment: Ensure the area around the nest is free from potential threats, like predatory pets. You can also offer nearby bird-friendly resources, like feeders or bird baths, to support the parent cardinals if they return.
Egg Relocation
Contrary to popular belief, cardinals do not relocate their eggs or babies to a different nest if they decide to abandon them. Instead, they opt to start anew, finding a new nesting site and building a brand new haven for their future offspring. This instinctual behavior ensures the best chances of success for their breeding endeavors, even if it means leaving behind their initial nesting attempt.
If you want to attract nesting cardinals to your yard, ensure you have left them plenty of cover and shrubs, food, and a water source. Cardinals not only mate for life, but will keep returning to the same area year and year.
Parental Care
The responsibilities of cardinal parents include feeding, protecting, and nurturing their offspring. From the moment the eggs are laid to the time the young birds leave the nest, the parents work tirelessly to ensure that their young are well-cared for. They diligently forage for insects, seeds, and fruits to provide a balanced and nutritious diet for their growing brood.
Feeding and Protection
Both the male and female cardinals take turns gathering food and guarding the nest. Their coordinated efforts enable them to stay vigilant against potential threats while ensuring the continuous provision of sustenance for their growing family.
This cooperative parenting approach showcases the deep bond and teamwork between the cardinal parents, as they dedicate themselves to the success and survival of their offspring.
