Physical Characteristics on Fledgling Northern Cardinal

When cardinals are born, they are completely naked and blind, with only a small quantity of feathery down to keep them warm. These tiny creatures are incredibly fragile and rely on their parents for their every need. Despite their vulnerable state, baby cardinals grow at a remarkable pace.

Baby cardinals start developing their downy feathers within the first week after hatching. By the end of the first week to ten days, they begin to look “fluffy” as the downy feathers give them a soft, rounded appearance.

This fluffy baby cardinal birds stage is a transition between their bare, newly-hatched state and the stage where they develop more defined juvenile feathers. As they approach the time to leave the nest, around 7 to 13 days post-hatching, these downy feathers are gradually replaced by their first set of juvenile feathers, which are more similar to adult plumage in structure, though not yet in color.


In terms of size and weight, young cardinals are small and weigh around 3.5g at birth. Their tiny bodies fit comfortably in the palm of your hand, making them a true delight to behold.

Week (After Hatching)Average Weight (grams)Notes
1st Week3 – 5 gramsRapid growth during first week
2nd Week15 – 20 gramsNearly fledging, much larger size
3rd Week25 – 30 gramsJust after fledging
4th Week35 – 40 gramsApproaching juvenile weight

Nesting Habits

Nest construction is an essential part of the nesting habits of baby cardinals. Both the male and female cardinals play an active role in creating a cozy home for their young ones during the breeding season. Once cardinals mate, they tend to mate for life.

Cardinals typically construct their nests in shrubs, trees, and even dense vegetation, providing ample protection and concealment for their offspring.

When selecting a location for their nest, cardinals often opt for places that are well hidden from predators. They have a keen eye for spotting secure spots that will keep their vulnerable chicks safe. The appearance of the nest varies, but it is typically composed of twigs, leaves, grass, and other natural materials.

Parental Care

Parental care is a crucial aspect of the survival and well-being of baby cardinals. Both the male and female cardinals actively partake in parenting duties, ensuring that their offspring receive the necessary nourishment and protection.

When it comes to feeding behavior, baby cardinals are fed insects and invertebrates by both parents. The adults tirelessly search for food to satisfy the growing appetites of their hungry nestlings. Not only do they provide whole food items, but they also regurgitate food into the open mouths of their chicks as a way to share nutrients.

Adult cardinals engage in protective behaviors to shield their young ones from potential danger. They fiercely defend their nests against predators and display aggressive postures and vocalizations to deter any threats. At this time its useful to provide extra food at the bird feeder.

The parents are also responsible for the maintenance of the nest, ensuring that it remains a clean and comfortable environment for their chicks.

Development and Growth

A baby cardinal bird will experience rapid development and growth. Within a short span of time, they undergo remarkable changes that enable them to become self-sufficient individuals. One significant aspect of their development is their growth rate. Baby cardinals grow quickly, and by around day 10, they are ready to leave the nest.

During their stay in the nest, baby cardinals gradually develop their eyesight. Initially, they are completely blind, relying solely on their parents to provide them with food and care.

However, as their eyesight becomes more acute, they are able to perceive the world around them, preparing them for their eventual departure from the nest.

Plumage Transformation

The plumage transformation of baby cardinals is a fascinating process to witness. Juvenile cardinals grow out their predominantly brown-gray plumage, which provides them with effective camouflage in their natural environment. However, as they mature, these colors give way to the striking red plumage that is characteristic of adult cardinals.

The molting process is responsible for the transition from juvenile plumage to adult plumage. Cardinals typically molt into their adult plumage during the winter months, shedding their old feathers and replacing them with vibrant red feathers. This transformation is truly awe-inspiring and marks the final stage of their journey to adulthood.

Diet and Feeding Habits – What do baby cardinals eat?

Baby northern cardinals show a particular affinity for insects and invertebrates. These protein-rich meals provide the baby birds with the necessary nutrients for their rapidly growing bodies. As mentioned earlier, parents feed their chicks whole food items, including small insects, caterpillars, and spiders.

Regurgitation of food is a common practice among adult cardinals when it comes to feeding their young ones. This process involves the parents partially digesting the food before bringing it back up and feeding it to their baby bird.

Usually its not parents feed baby cardinals, the male feeds the female and the female regurgiates for the babies in the cardinal nest.

It may not sound appealing to us, but it is an essential mechanism that ensures the proper nourishment of baby cardinals. To encourage cardinals to your yard, ensure you leave plenty of cardinal food and provide adequate protection.


Reproduction is a crucial phase in the life cycle of baby cardinals. It marks the beginning of a new generation and ensures the continued existence of these beautiful birds. The process of reproduction involves the female cardinal taking the lead and fulfilling various roles.

Female cardinals lay eggs – typically between 1 to 5 eggs, with 2 or 3 being the average. The eggs are carefully placed in the nest, where they are incubated for approximately 11 to 13 days.

During this period, the female cardinal diligently tends to the eggs, ensuring they receive the warmth and protection necessary for successful hatching.

Incubation Period

The incubation period is a critical time for the development of baby cardinals. It is during this phase that the cardinal eggs are kept warm and receive the necessary nurturing from the parents. The length of the incubation period for cardinal eggs typically spans around 11 to 13 days.

The female cardinal plays a significant role in the incubation process. She remains devoted to her task, rarely leaving the nest and diligently maintaining the optimal temperature for the eggs’ development. The male cardinal also provides support, occasionally relieving the female from her duties to allow her to rest and replenish her energy.

How Long do Baby Cardinals Stay With Their Parents?

Fledging refers to the process of a juvenile cardinal leaving the nest and becoming independent. It is an exhilarating moment in their lives and signifies their readiness to explore the world on their own. Baby cardinals leave after 7 to 13 days, but despite leaving the nest, they still rely on their parents for nourishment.

During the fledging stage, the parents continue to feed their young ones for a period of up to two months or longer. This extended period of parental feeding, especially by the female northern cardinal, ensures that the fledglings receive the necessary sustenance as they learn to fend for themselves. The parents tirelessly work to provide their offspring with a smooth transition into adulthood.

FAQS on a Cardinal Fledgling

How do you identify a baby cardinal?

Baby cardinals, or nestlings, are initially blind, featherless, and have a pinkish or reddish skin tone. As they grow, they start to develop light gray or brownish downy feathers. Juvenile cardinals, which are a bit older, are typically covered in a mix of brown and tan feathers, with males beginning to show tinges of red. Both males and females have a distinctive crest on their heads, even at a young age.

Do baby cardinals stay with their parents?

Yes, baby cardinals remain with their parents for several weeks after fledging. The parents continue to feed and teach them vital survival skills, like foraging, during this period.

How long does it take for baby cardinals to turn red?

Male juvenile cardinals begin to show some red plumage as early as their first molt, which can be a couple of months after hatching. However, the male northern cardinal juveniles don’t achieve their full vibrant red coloration until after their second year. Female cardinals will always be more subdued in color, with shades of tan, brown, and subtle red accents.

How old are baby cardinals when they fly?

Cardinal chicks, or fledglings, usually leave the nest, or fledge, when they are about 7 to 13 days old. At this point, they start making short, clumsy flights.

How long do cardinal fledglings stay on the ground?

After fledging, cardinal fledglings might spend a few days to a week on or near the ground, taking short flights and gradually building their flying skills. During this vulnerable period, the parents continue to watch over and feed them. Over time, these young birds become more adept at flying and spend less time grounded.

What does a baby cardinal look like?

A baby cardinal, when first hatched, is largely naked with only a few wisps of downy feathers. Their skin appears pinkish or reddish, and they are blind with their eyes closed. As they grow over the first week, they begin to develop a light gray or brownish down, giving them a soft, fuzzy appearance. Their eyes will also open during this period. By the time they are ready to leave the nest, which is usually around 7 to 13 days after hatching, they sport a mix of brown and tan feathers. Juvenile cardinals retain this coloration for some time, with males gradually acquiring the signature red plumage as they mature. Both male and female baby cardinals will have a noticeable crest atop their heads, a defining feature of the cardinal species.
