Ahem. The Blue Tit or Cyanistes caeruleus – sporting vibrant colours of blue, yellow, white and green – are commonly found in Western Asia and all over the UK, exceptions being some Scottish islands. They’re fond of woodlands, hedgerows, parks, and gardens. They love to munch on insects, seeds, and nuts while they Netflix and chill.
Really, though. What did you think this post was about? Hmm?
Anyway, they’re quite abundant, across Europe they have a count up to 20-44 million pairs!

It’s noted that a key to their sustained numbers is their taking advantage of nesting boxes and bird feeders (as do the Great Tit in this regard) people have set up, I imagine most in their gardens and backyards. However, domestic felines are the leading cause of mortality for this lot.
Ordinarily, they’d set up house in holes in trees but blue tits have been recorded to nest in a variety of inventive substitutes, like post boxes and street lamps, to cigarette bins and exhaust pipes.
