Tweet of the Day is the voice of birds and our relationship with them, from around the world.

Sir David Attenborough presents a seabird with a worldwide distribution, the brown noddy. Expert fliers, the brown noddy is seldom seen near land and is highly pelagic, wandering extensively in warm tropical waters where it searches for small fish and squid which are captured by hover-dipping and contact-dipping. However in the Galapagos Islands, brown noddies have learnt to sit on the heads of brown pelicans hoping to steal fish from their open gular pouches; a behaviour known as kleptoparasitism (literally, parasitism by theft).
