Sumer visitors

Today I was on my own again and will be tomorrow so lunchtime walks are even more appreciated even though I'm very busy.  It was still quite a nice temperature (short sleeves) and I even saw the first summer migrant - a house martin swooping over the firewater lake.  Apparently peregrine falcons are nesting in the pipe ducts of one of the manufacturing buildings so might see if I can get permission to take the camera on to plant.
