In addition to its carnivorous diet, the Common Redshank also supplements its food intake with small fish. While not a primary food source, fish provide an additional source of protein and nutrients for the bird. The Common Redshank is able to catch fish by swiftly striking at them with its bill when they come within range. This opportunistic feeding behavior allows the bird to take advantage of available prey in its environment, further diversifying its diet.

Breeding Behavior and Life Cycle of the Common Redshank

The breeding behavior of the Common Redshank is truly remarkable. They typically form monogamous pairs that return to the same breeding territories each year. The males engage in elaborate courtship displays to attract the females, involving aerial displays, vocalizations, and synchronized movements. Once a pair has formed, they build a nest together on the ground, often in a well-hidden location within vegetation or along the shorelines of wetlands. The nest is a shallow scrape lined with grass, leaves, and other materials.

After the female lays a clutch of four eggs, both parents take turns incubating them for approximately 22-24 days. Once the eggs hatch, both parents provide care and protection for the chicks, which are covered in downy feathers and are precocial, being able to leave the nest and feed themselves shortly after hatching. The parents guide their young, teaching them essential skills such as foraging techniques and predator avoidance strategies. The young redshanks fledge when they are around 30-35 days old.

During the breeding season, the Common Redshank displays territorial behavior, defending its nesting area from intruders. Both males and females actively patrol their territory, engaging in aggressive displays and vocalizations to deter potential threats. These displays often involve raising their wings, puffing up their chests, and making loud calls to assert their dominance.

Migration Patterns and Seasonal Movements of the Common Redshank

The Common Redshank is a migratory bird species, with different populations traveling varying distances to their non-breeding grounds. Birds breeding in northern parts of Europe and Asia undertake extensive migrations to reach their wintering areas in Africa and other more southerly regions. The journey can be thousands of kilometers long, and redshanks navigate using various environmental cues, including the Earth’s magnetic field and celestial navigation. Migration typically occurs during autumn and spring when suitable habitats and food resources become limited in the breeding and wintering areas, respectively.

During migration, the Common Redshank forms large flocks, often consisting of hundreds or even thousands of individuals. These flocks provide protection against predators and help the birds conserve energy during their long journeys. The redshanks fly in a V-formation, taking turns at the front to reduce wind resistance for the rest of the flock. This cooperative flying behavior is known as “migratory drafting” and allows the birds to travel more efficiently.
