Ant Hills

Some old pastures and just a succession of anthills and their size can indicate the time that the field has been pasture as they grow very slowly in height each year. Whilst the anthills in the meadows here get knocked down each year when the hay is cut the ones outside the meadow are left to grow in size and I would estimate they add an inch or so in height each year or maybe a little less. They are formed by Yellow Meadow Ants. One side benefit is that we get regular visits from Green Woodpeckers whoc come to feed on the ants. The photo is one on the side of the drive.
