Now I know why

.....the fat is disappearing at an alarming rate.

The birds in the neighbourhood have told each other that the grubs really good at my house.

These three, or at least three great tits were continually on the fat for some time.

Earlier in the day it had poured with rain but the weather improved in the afternoon so we had a BBQ.  While we were eating Murphy was watching something in the bushes.  It was one of the baby blue tits.  The mum and dad were racing back and forward looking after him.  It was late in the evening so I don't know whether he will survive the night. Nature will take its course.
