The de Havilland DH.53 Humming Bird is a British single-seat, single-engine, low-wing monoplane light aircraft first flown in the 1920s.In response to the Daily Mail Light Aeroplane Competition of 1923 de Havilland built two DH.53s which were named Humming Bird and Sylvia II.[2] After the trial, Humming Bird was reengined with a 26 hp (19 kW) Blackburne Tomtit two-cylinder engine, and the aircraft was fitted with a revised undercarriage.[3] Early in 1924 twelve aircraft were built at Stag Lane Aerodrome and were named Humming Bird after the first prototype.[4] The first six aircraft for the Royal Air Force all made their public debut at the 1925 display at RAF Hendon, where they were raced against each other.
