The yellow-billed tropicbird, known scientifically as *Phaethon flavirostris*, is a seabird found primarily in tropical and subtropical regions. It is easily recognizable by its striking yellow bill and long tail feathers. These birds typically inhabit coastal areas and are often seen soaring over the ocean, where they hunt for fish and squid. Yellow-billed tropicbirds are known for their graceful flight and distinctive calls. They nest on rocky cliffs or in crevices, laying a single egg that both parents incubate. Their diet mainly consists of small fish, which they catch by diving into the water from the air.
