Monogamy in the Animal Kingdom

General concepts of monogamy

Monogamy, in the context of the animal kingdom, refers to the practice of maintaining a single mating partner for a particular period. This period can range from a single mating season to a lifetime, depending on the species. Different species practice different forms of monogamy. There are two main types:

Sexual Monogamy – This refers to animals that mate with only one partner during a particular period. This partner may change over different periods.
Social Monogamy – This refers to animals that maintain a single partner for social activities like nesting and rearing offspring but might mate with other partners.

Monogamy is an intriguing behavior, especially considering that only about 3-5% of mammalian species practice it. It’s even rarer among invertebrates and fish. However, the story changes when we explore the world of birds.

Monogamy in birds

Birds are a fascinating exception when it comes to monogamous relationships in the animal kingdom. More than 90% of bird species are monogamous, at least in the social sense. This is predominantly because of the extensive care most bird offspring require to survive.

Raising a brood is often a demanding process, involving building nests, incubating eggs, feeding hatchlings, and protecting them from predators. In many bird species, this is a two-parent job. So, monogamy becomes a practical and efficient strategy to ensure the survival of their progeny. For many birds, including Cardinals, this monogamous behavior extends beyond mere practicality into the realm of complex social interactions and bonding rituals.

Understanding Cardinal Monogamy

Cardinals are known to be monogamous birds. They typically mate for life and form strong pair bonds. Once a male and female Cardinal find a mate, they will stay together year-round and often remain paired for multiple breeding seasons.

Cardinal pair bonding

Pair bonding refers to the strong affinity established between two individuals, leading to a long-term relationship. In Cardinals, this bonding process is intense and fascinating.

Courtship Feeding – This is a common practice where the male Cardinal feeds the female. This not only signals the male’s ability to provide food but also strengthens the bond between the pair.
Singing Duets – Cardinals are known for their melodious tunes. During courtship, males and females often engage in duet singing, further cementing their bond.
Defending Territories Together – Once paired, Cardinals jointly defend their territory against intruders. This joint venture is a testament to their strong pair bond.

Cardinal mating rituals

The Cardinal mating rituals are an elaborate display of affection and commitment.

Mate Feeding – Before copulation, the male Cardinal often feeds the female as a part of the mating ritual.
Bill Wiping – Both Cardinals engage in bill wiping on a branch or other surface, which is thought to be a part of their bonding ritual.

Cardinal nesting behavior

The nesting behavior of Cardinals further strengthens their monogamous relationship.

Shared Responsibility – Both male and female Cardinals take turns to incubate the eggs. The male Cardinal will also feed the female while she incubates the eggs, showcasing their shared commitment to their offspring.
Nest Building – The female Cardinal usually builds the nest, while the male guards it. This coordinated effort highlights the strong bond between the pair.

Cardinal Parental Care

Role of both male and female Cardinals

In the world of Cardinals, both parents play a significant role in raising their offspring, an aspect that strongly supports their monogamous nature.

Male Cardinal’s Role – After the eggs are laid, the male Cardinal takes on the duty of protecting the nest and feeding the incubating female. After the chicks hatch, the male continues to protect them and helps the female in feeding them until they’re ready to leave the nest.
Female Cardinal’s Role – The female Cardinal primarily constructs the nest and incubates the eggs. Post-hatching, she shares the feeding duty with the male until the chicks become independent.

Cardinals’ life cycle in relation to their monogamous behavior

Cardinals’ monogamous behavior is strongly intertwined with their life cycle:

Mating and Nesting – During the mating season, Cardinals form monogamous pairs, engage in courtship behaviors, and jointly protect their territory. This stage culminates in the laying and incubation of eggs.
Parental Care – Post-hatching, both parents take on the responsibility of feeding and protecting the chicks. This shared responsibility nurtures their bond further.
Post-Breeding Season – Even outside the breeding season, Cardinals often stay together, maintaining their pair bond. This non-breeding period solidifies their bond, preparing them for the next breeding season.

By studying Cardinal parental care and its connection to their life cycle, we gain deep insights into their monogamous behavior.

Monogamy vs. Polygamy in Cardinals

Benefits of monogamy for Cardinals

Monogamy in Cardinals provides several benefits which help ensure the survival of their species.

Shared Parental Duties – By sharing parental responsibilities, Cardinals increase the chances of their offspring’s survival. Both parents contribute to nest building, feeding, and protection from predators.
Territory Protection – As a bonded pair, Cardinals jointly defend their territory, ensuring a safe space for nesting and raising their young.
Stronger Genetic Lineage – Monogamy can result in a stronger genetic lineage. By selectively choosing a mate, Cardinals can pass on desirable traits to their offspring.

Are there any exceptions?

Even though Cardinals are generally monogamous, there can be exceptions to this rule, much like in any other animal species.

Extra-Pair Copulations (EPCs) – Rare instances of Cardinals mating outside their pair have been reported. However, such occurrences are infrequent and the exception rather than the norm.
Re-mating after Loss of Partner – If a Cardinal loses its partner, it will typically find another mate. This adaptive behavior ensures the continuation of their genetic line.
Polygamy due to Resource Availability – In cases where resources are plentiful, occasional polygamy has been observed, where a male Cardinal might mate with more than one female.

While Cardinals predominantly exhibit monogamous behavior, understanding these exceptions gives us a holistic view of their mating patterns. This awareness not only enhances our knowledge of Cardinal behavior but also enriches our birdwatching experiences.
