The red-knobbed coot (Fulica cristata), also known as the crested coot, is a distinctive waterbird belonging to the rail family, Rallidae. While it shares a nearly identical black-bodied profile with its close relative, the common Eurasian coot, it features striking unique anatomical details.
Key Identification Features
• The Red Knobs: The most diagnostic feature is the pair of small, dark-red fleshy knobs at the top of its white frontal shield. Note that these knobs swell and become much more prominent during the breeding season.
• Plumage & Bill: It possesses entirely slate-black plumage contrasting sharply with a bright white bill and facial shield.
• Feather Shape: The lower edge of its white frontal shield rounds into a smooth, seamless curve where it meets the feathers—unlike the Eurasian coot, which has a distinct angular wedge shape cutting into the plumage.
Habitat & Behavior
• Distribution: This species is a resident breeder across much of Africa and survives in heavily fragmented, rare pockets of southern Spain and Portugal.
• Habitat: They inhabit freshwater lakes, wetlands, ponds, and slow-moving rivers with plentiful marginal vegetation.
• Diet: Primarily herbivorous, they dive underwater or graze along the shoreline to feed on aquatic plants, seeds, and small invertebrates.
• Nesting: They build large floating platforms constructed out of dead reeds and aquatic vegetation anchored near the water's edge.
