The RSPB get many reports from the public about ""exotic" bird sightings that more often than not turn out to be a jay. Not surprising given it's plumage, and the funerial black of our other corvids. First time i saw a tree-creeper i thought it was rare, never having seen one before, drab feathers but unmistakable behaviour, but not uncommon. Buzzards have become main-sream nowadays, same with herons. A goldcrest just outside the window, tiny yet can lay 7 or 8 eggs again not rare just reclusive, and like wrens, not attacted to bird-feeders, prefering insects to seeds.
