This year it dropped from third to fourth place behind the tree sparrow, the blue tit and the wood pigeon.

Ms Gray described how her mother's stone featured a ball of wool and knitting needles, because she loved to knit, as well as a blue tit, because she enjoyed watching the birds in her garden.

Researchers found that years when moth numbers were up resulted in increased population growth for the blue tit.

At Morriston Park in Swansea, near his home, the then nine-year-old ticked off sparrows, starlings, blue tits…but surely not a ring-necked parakeet, external?

Birds will adjust their foraging behaviour around a reliable source of supplementary food; Dr Lees says the diminutive blue tit will fly several kilometres to reach a reliably topped-up feeder.
