Question: what is the difference between a house sparrow and a dunnock?
Answer: The Dunnock is similar in size to the House Sparrow, though it is a sleeker bird with a fine bill. The plumage is rather drab, being a mixture of grey on the head and chest and brown elsewhere. ... Dunnocks are usually seen foraging on the ground, shuffling about 'mouse-like' in search of food, the tail moving nervously.
