UK Green Adventures: The Great Bird Hunt – Species 21-25
This article will introduce you to 5 of the most common seen ducks around town ponds and wetland sites.
There are plenty of ducks that all look very similar to the naked eye – especially the females, so these descriptions are focused mainly on the males as they are the most likely ones you will pick out in the water. They will be in their display colours as they try to find a mate.
Most of the time in the spring and summer, the females will be close by the males as well for breeding – or will already be closely followed by a herd of ducklings – so you can start to practice the differences in the females once you have mastered their associated males.
However, outside of the breeding season, most male ducks moult into what is known as their ‘eclipse’ plumage, which is quite different to their summer splendour!
They all turn into rather drab birds – looking very similar to their female friends. Well, they don’t want to stand out to predators when they don’t have to!
Anyway, straight to it then with a firm favourite:
Mallard:
We should all know this one purely because it is always about on almost every pond or canal where there are humans – as they know that we will probably feed them!
As a result, they are usually quite bold birds and will waddle over to us for priority feeding if there are other birds like Mute Swans about!

Key points of the mallard male is his beautiful green head, pinched in by a white collar but there are several others ducks with that feature too. So you will have to look for other signs: like he will also have a bright yellow bill which seperates him from some of the other similar birds.
Another point is that he will have blue patches on his wings rather than white or green (not visible in this image) – and in flight these show as a blue bands with white edging.
Shelduck:
Here is another one with a green head – but he has some more striking features to tell him apart. Both male and female look the same; bright white birds (very goose-like) with a band of brown across the shoulders, then a thick collar of white before the dark green head and bright orange beak! You won’t be able to miss them once you see them.
The main and obvious difference between the sexes is that the male has an extra ‘knobbly’ bit at the top of his bill – as in the image below – a bit like the Mute Swans.
Shoveler:
Another green-headed common bird is the Shoveler – so called because of its very wide black shovel-shaped bill.
It sits lower in the water than a mallard, and has a noticable yellow eye when viewed at close range. It has the same broad white neck as the Shelduck with brown shoulders and sides too, but there the similarity ends. This bird has a very low profile where the Shelduck sits high in the water and is more ‘white’.

Goldeneye:
As its name suggests it has a bright golden eye set bold in its green head – but manages to look nothing like the Shevelor despite this!
It has a much more rounder, pronounced head that looks like it has been stuck onto the body like a giant pom-pom! It also has a bright white cheek patch beside its smaller, pointy bill. The rest of the body is very pale with and almost stripy back where black and white feathers mix as shown below:

Mandarin Duck:
No need to worry about the green head for this one as there is too much else to give it away! This species is one of our most decorative and colourful ducks – if not birds – in the UK and you can see them quite frequently in wetland reserves.
They are difficult to describe as there is so much to say – so look at the picture below to be amazed! They have delicate patterning on their seemingly ‘giant’ cheeks if you look close enough; their long white eye streak goes on forever; and they have the most unusual orange ‘sails’ jutting up from their wings when they are on the water.
And the bright blues and purples……

Next time you head out to the wetlands – have a look for these males – and try to find their partners hidden among all the other brown looking birds on the water!
See you soon…..
