I should not grumble

I shouldn't grumble I suppose
when pigeons eat the crab apples.
They've taken all the orange ones
Before the bedroom window
Wondered what all the fuss was
They've not been here for months
There's a red one by the drive
Always red at Christmas
But not this year I bet.
Blackbird,who watches over me
and has for many a year
scratches in the lawn and shrubs
but doesn't sing upon the roof.
The storms are unopposed
the gable top quite empty.
I miss the other birds,
tits and finch and Christmas robin.
The food's all theirs to see
Why don't they come?
No I won't grumble at the pigeon,
there's bread enough to spare.
