SIR - Dr Drew Whitelegg of Atlanta GA USA asks if any one has noticed a decline in house sparrows.

I am sorry to have to tell him that they are on the red list of endangered species.

No one is sure why, but loss of habitat is one possible reason.

On a more positive note, in last year's RSPB big garden bird watch I saw just four sparrows.

This year I saw 10 or more. If your readers wish to help stop the decline then contact the RSPB.
