Seems like from the M74 to Thornhill is a spot without themI used to see 5 or 6 regulalry most mornings as u drove up the apr on the same restock site on west side of 74.
Dunno how long ago that will be now. But it was when they were building the windmills and it was just before u got to the site offices and the double entrances just before little clyde fly over.
But there doesnae seem to be big numbers over the west side and never heard off them moving very far south down that side
