In this month's Gardener's World magazine,[page 96], regarding the rapid decline of house sparrows, my husband & I have spent many happy hours just lately watching dozens of parents feed their young on our seed trays, one poor soul had three youngsters all begging to be fed at once. Some fledglings, if ignored knew exactly what to do & fed themselves when the parent flew off.
We, in Yorkshire have siskins,bluetits,coaltits,long tailed tits,robins,hedge sparrows,collared doves, wood pigeons, a kestrel, a sparrow hawk & a heron looking for a meal from a neighbour's fishpond. So Mr Moss, if you want to see a lot of house sparrows at close quarters [we sit just six feet away from the feeders] come to Pudsey & have a cup of tea.
