I think I have once seen one sparrow here. They are definitely in decline in this area.
One year, a couple of decades back, there was a large flock down on the marshes in a wheatfield, and, flocking with them, two budgerigars, one green, one blue. I wondered if they were talking sparrow, to fit in. Now I haven't seen a single bird, let alone a flock for years.
