Tree Sparrows are regularly on the feeders again. Two or three visit at the moment though I expect this number will increase as autumn turns to winter. Last winter we had eight visiting on a regular basis. This morning I saw a good flock of about 20 in a hedgerow bordering a stubble field. Tree Sparrows do well in this area despite suffering a very sharp national decline in the last three decades(95% between 1970 and 1998 according to the Breeding Bird Survey). They make a good subject to draw with bold head markings, especially the distinctive cheek spot which is one feature that sets them apart from House Sparrows.
