Yes. Frillback pigeons, like all pigeons, are capable of flying. They have strong wings and a compact body structure, making them well-suited for flight.  However, Frillback pigeons are often bred for their unique appearance, which includes the characteristic frill of feathers on their back. This frill can interfere with their ability to fly, adding extra weight and drag to their body. As a result, many Frillback pigeons may not fly as well as other breeds of pigeons.
