Pigeon Brain

For reasons best known to itself this pigeon was getting its exercise by fluttering from the rotary clothes airer to the bird bath, and back again.  it may also have been responsible for uprooting the lilies from a pot and tossing the chewed bits all over the lawn.  I feel like deducting the cost of replacement lilies from its pocket money.  Except that pigeons don't have pocket money.  It may be, of course, that I should be blaming a squirrel.  I don't think squirrels have pocket money either.
