On the east side of the garden our neighbours have a substantial (for Shetland) fir tree in which the Hooded Crows successfully nest and on the west we have neighbours who have a cat. As a result of being in the middle we witness a constant battle between the nervous crow parents and the cat. Here the crow is watching to see the next move of its feline foe. For the record I am more a crow person that cat.
Note the high tech device at the end of the old workshop to stop birds nesting. A spare drinks can.
