House Sparrow
Passer domesticus
This male was joined by a female house sparrow and both were following tourists ready to snatch fallen crumbs at Fort Jesus, Mombasa, Kenya. January 2012.
From Wikipedia: House Sparrows are found in most parts of the world. A small bird, it has a typical length of 16 centimetres and a weight of 24-39.5 grams. Females and young birds are coloured pale brown and grey, and males have brighter black, white, and brown markings. One of about 25 species in the genus Passer, the House Sparrow occurs naturally in most of Europe, the Mediterranean region, and much of Asia. Its intentional or accidental introductions to many regions, including parts of Australia, Africa, and the Americas, make it the most widely distributed wild bird. The House Sparrow is strongly associated with human habitations, and can live in urban or rural settings.
Ranging today mostly at the coast and along highways as far west as Nairobi. Kenya's population probably originated from India.
