Why is this garden bird like the River Thames?





When the Thames rises in the Cotswolds, it is called the Thames, and when it gets to the home counties, it is called the Thames, but when in Oxford it is called the Isis. (At least by some people).

Birding can be complicated. I knew this bird in Kenya and Tanzania (or some of its relatives anyway) as the White-browed Robin-Chat. My Southern African bird books (two, lots of nice pictures, cover several countries but not Malawi) call it the same. My Malawian bird books (no pictures but a lot of distribution maps) call it a Heuglin's Robin. They do something similar for other Robin-Chats too. Wikipedia can't tell me why there is a difference so I guess no-one knows,   probably including the bird.

PS for the geeks: Heuglin was a 19th century explorer/administrator in NE Africa best known for his ornithology. Several birds are named after him. The Latin name is C. heuglini and the Afrikaans name is janfrederiks.
