Red-knobbed coot

The red-knobbed coot, also known as the crested coot, is a remarkable bird belonging to the rail and crake family, Rallidae. This species is primarily found in Africa and southern Spain, typically inhabiting freshwater lakes and ponds. Nesting habits of the red-knobbed coot are quite ingenious—it constructs its nest from dead reeds either right at the water's edge or even floating on the water. The species usually lays around eight eggs; however, due to its somewhat aggressive disposition towards its young, only a few chicks manage to reach adulthood.

In terms of appearance, the red-knobbed coot is predominantly black with a distinctive white frontal shield. It measures approximately 38–45 cm in length and weighs between 585–1,085 grams. Its toes are partially webbed, aiding in swimming. Juvenile coots appear different from adults, being paler with whitish breasts and lacking the facial shield. Distinguishing the red-knobbed coot from the Eurasian coot can be challenging, but a key identifier is the presence of tiny red knobs on its facial shield that become prominent during the breeding season.

Similar to the Eurasian coot, the red-knobbed coot is highly territorial and can exhibit aggressive behavior, especially during the breeding season. This bird is not particularly fond of flying and often prefers to run across the water's surface to take off. As an omnivore, it consumes a variety of small live prey and aquatic plants, with a particular preference for Potamogeton species.

During mating season, the red-knobbed coot produces distinct vocalizations that differentiate it from the Eurasian coot. Its calls include a rapid "kerrre" a harsh "ka-haa" and a grunting hoot "oot oot." These unique sounds, combined with its behavior and diet, make the red-knobbed coot a fascinating and unique member of the rail and crake family.
