Nesting and Reproduction

The African Green Pigeon (Treron calvus) is a monogamous species, meaning that pairs form strong bonds and work together to raise their young. Their nesting behavior is essential for the continuation of their species, ensuring the survival and propagation of future generations.

The African Green Pigeon typically nests in tree forks, selecting locations that offer an adequate vantage point of their surroundings. This strategic choice provides a clear view of potential threats and allows them to monitor their nest and young. The nest itself is a simple platform constructed of sticks, collected by the male and carefully arranged by the female. The female takes the lead in building the nest, using the materials provided by her partner. This collaborative effort demonstrates the importance of teamwork in their reproductive strategy.

Nesting can occur throughout the year, but it is most common during the summer months. The female lays 1-2 eggs, which are incubated by both parents. Incubation typically lasts 13-14 days, during which time both parents share the responsibility of keeping the eggs warm and protected. Once the chicks hatch, they are cared for by both parents, who feed them with a nutritious mixture of crop milk and regurgitated food. The chicks remain in the nest for about 12 days, during which time they are constantly monitored and protected by their parents.

The African Green Pigeon's nesting and reproductive behavior is a testament to its dedication to its offspring. Their collaborative approach to nest building, incubation, and chick rearing ensures the survival and success of their young.
