Long-tailed Tits (Aegithalos caudatus) are the cutiest tits I've ever seen!

Long-tailed Tits are otherwise tiny rounded birds with strikingly long tails.
No closely related species are found in Finland. They have snowy white heads and underparts,
with greyish or pinkish tints visible on their bellies and undertail coverts.
Their wings and back have black, white and reddish markings.
Finnish breeding population estimated at 20 000–40 000 pairs.
