(1) Kingfisher
This had to come in at number one, probably the most famous British bird for its striking plumage. Often it is purely seen as a dash of blue and orange as it zooms across a river, possibly darting in to get a fish if you are particularly lucky on its way.
(2) Green woodpecker
All the woodpeckers are striking birds, and the brilliant red, black and white of a greater spotter and lesser spotted woodpecker could also make the list. But the green woodpecker is a pretty striking bird, with its green plumage (rare for any bird) and its bright red crest, this truly is a spectacular looking bird.
(3) Bullfinch
The bullfinch has a deep pink breast, and is a very colourful bird indeed. Unfortunately it is quite hard to spot and so many people have probably never seen a bullfinch in their lives, but if you do it is a treat. Therefore the next bird is offered as a common alternative that is still very colourful.
(4) Chaffinch
... or more specifically, the male chaffinch, which has some lovely colours. Unfortunately the female chaffinch as very different and has rather dull colours, so it is definitely the male chaffinch that you want to see if possible!
(5) Long-tailed tits
There are several colourful tits, and even the most common blue tit is colourful with its blue and yellow, and the great tit has the striking black colouration to it. However the long-tailed tit with its very long tail and its pink, white and black plumage is a particularly striking bird and therefore definitely deserves its place on this list.
(6) Puffin
When you see a puffin in Summer and its beak has the range of wonderful colours like blue and red and orange, against the black and white plumage, then this distinctive bird is certainly very colourful and a treat to watch.
(7) Jay
A member of the crow family, this bird has very distinctive colours and is a very striking bird indeed. Although less common than things like a crow or magpie, you can often see it in gardens particularly around the Autumn and in the Winter when it seems to be a lot more active in these locations.
(8) Goldfinch
A bird that has bright red and the striking yellow or gold wingbar after which it is named, and in flight you can just see a rush of gold as it flies past, this truly is a very colourful bird indeed.
(9) Robin
With its bright red breast, and being so symbolic of Winter and Christmastime on Christmas cards etc, this is a very colourful bird indeed.
(10) Nuthatch
A very interesting bird and particularly fun to watch too as you see it climbing the bark of a tree directly which is quite unusual to see in a British bird (possibly unless you are watching a treecreeper), and the nuthatch has very striking colouration with the orange, blue, black and white combination of colours that it offers.
