Long-tailed tit (Aegithalos caudatus)
Distinctive, undulating, gregarious, and a lover of small and excitable flocks, the Long-tailed tit is, as a matter of fact, one of the smallest garden birds in the UK. If not for its extensively long tail, the most characteristic part of the bird, it would be tiny and measure just 6cm in length.
The Long-tailed tit is somewhat fluffy in appearance, almost adorable (called a “tiny ball of fluff,” in the Guardian) and features a short, stubby bill. There’s very little difference between males and females, both of which develop plumages of mainly black and white with clear gradations of grey and pink. Many times people have observed with an “aw, isn’t that cute” after spotting a Long-tailed tit roaming casually around.
Distribution
Long-tailed tits are a widespread species, spanning the whole of northern Europe and Asia, even going as far south as the Mediterranean. Its favoured residence is deciduous woodland with large areas of shrubbery and heathland. They are also common in parks and gardens; make sure to look out for oak, ash and sycamore trees, as these are favoured among Long-tailed tits.
They are a predominantly sedentary UK bird, visible all-year-round, but have a tendency to move at furthest just short distances from their nesting sites. This they would only do when moving in flocks of roughly twenty birds, and generally only within winter feeding territories.
“The tiny Long-tailed tit is so small that it is very vulnerable to cold weather. In harsh periods, as many as 90 per cent may die.” Michael McCarthy, Independent.
Although Long-tailed tits ordinarily have a tough time over winter and can rapidly decline in numbers, they have, as of late, been faring well due to the consistently mild UK winters (written as of April 2017). In those harsher winters, Long-tailed tend to huddle together to preserve warmth. Furthermore, in this article by the BBC, there’s evidence to suggest that Long-tailed tits flock together over winter to maintain warmth. Smaller birds, by their very nature, have a tendency to lose more body heat than their larger counterparts; they could risk dying if a partner isn’t found, so Long-tailed tits group together and flock in related numbers: brothers, sisters, aunts, uncles all form these unique groups.
Long-tailed tits are recognised as Least Concern, with only distant populations on the fringes of distribution facing trouble.
Feeding behaviour
Long-tailed tits are year-round avid fans of insectivores, with a preference for eggs and larvae of moths and butterflies. Over recent years, due to the popularity and commonality of feeding areas in gardens across the country, Long-tailed tits have increasingly been attracted to peanuts and suet foods.
Altruism of Long-tailed tits
Long-tailed tits have one of the highest nest failure rates among garden bird species. However, despite this disconcerting fact, it is interesting to observe that Long-tailed tits have a habit of not re-nesting. Instead, they will become what are known as “Helpers”; supporters of a nest or other pair of birds, a behaviour known as co-operative breeding. According to Wikipedia, “approximately 50% of nests had one or more helpers.” This altruistic behaviour pertains to a fitness advantage, particularly if it is related to offspring that is supported by the helper. In a future scenario, the helper can use its experience supporting a particular nest for its own offspring in the next season.

John Clare wrote a poem in which Long-tailed tits were called “Bumbarrels”, a reference to their barrel-shaped nests:
And coy bumbarrels twenty in a drove
Flit down the hedgerow in the frozen plain
And hang on little twigs and start again.
There seem to be two main colourings of long tailed tits however in S Devon the darker is more common and the white rarely seen. Their nests are constructed of sphagnum type moss stuck together with cobwebs. These well camouflaged nests are constructed around a twig or slim branch and have a small side opening. Adults who are brooding eggs end up with bent tails
We have our first long tail nest in amongst the rosa rugosa next to the wahing line!
I see long-tailed tits infrequently – although when I do they always seem to attend the feeders in pairs, which is very cute.
I have a flock of long tailed tits that regularly visit my garden and have done so for years now. They love the insect suet block.
For the past three days we have had a little fella who sits on our windowsill and taps at the window. We’re thoroughly enjoying watching these close up antics but it is driving our cat crazy! We wonder if he is looking for a larger space in which to nest – our living room perhaps?
Does anyone whether this is usual behaviour for long tailed tits?
I had never seen this bird at my garden feeder before, so it took a bit of looking up to identify it. There seems to be a small flock of them now. I will have to look up their song too.
We have 3 visiting us over the past wk I’d love them to stay and bring more friends, here’s hoping they survive if we get a jan/ Feb cold spell
Very rare sight, but I hope this is a good start.
So small you’d easily miss it.
I was invaded by a flock of them mid morning – I have seen a few before but never as many as there were this morning – they came and went just as quick as they had appeared. What a treat ☺️.
