The Great tit (Parus major) is large and robust with a relatively heavy bill and domed head. The most widespread of all the species of tit, it is found across almost all of Europe and east to Japan and south to Indonesia. It is also found in North Africa. It is resident, and most birds do not migrate. There are some 30 different races of great tit, many of which are predominately grey and black and lack the bright yellow of European birds. Great tits invariably nest in holes, but here they can be remarkably inventive, often using manmade sites such as post boxes.
