HouseSparrow

Here is a house sparrow sitting on a lobster pot on the Northumberland coast. You can tell that it is a house sparrow rather than a tree sparrow because of the grey crown (top of the head). A tree sparrow has a rich brown head without the grey crown.

In the UK numbers have declined dramatically over the last few decades, along with the tree sparrow (97% of which have disappeared since the 1960s). However according to Wikipedia the house sparrow is considered an unwanted pest in many parts of the world, having been deliberately or accidentally introduced and they are hunted down and exterminated. Maybe they should send theirs over here?
