As part of the ‘Making Wildlife Watching Easy’ series, here’s a nice simple wildbird guide: How to tell the difference between Blue Tits and Great Tits.
These 2 garden birds are both small, both love feeders, both look blue and yellow and both sing pretty songs – so how can you tell them apart?
Well the answer is ‘easily, if you know what to look for’.
So, what is the difference between a Blue tit and a Great tit?
Well, there are many differences, but the easiest thing to spot at the feeders is that the Great tit has an almost entirely black head and neck apart from a giant white cheek pouch – see below:
Once you can spot this – all the other differences aren’t so important. However saying that, I still haven’t got it spot on yet. I have to watch them for a while until I am sure.
And although pictures of them side by side can clearly show you the differences, when they are upside on a feeder with 10 other Blue or Great tits – it’s not so easy, so you can also look at their behaviour too to tell them apart.

Blue tit on the left and Great tit on the right. Did you get it?
So, based on your observations outside – I have written down the main differences below as they are ‘clear’ differences – things that you can see in a second – rather than saying Species A has ‘a slightly bigger patch of white’, etc. These things should be obvious to you, with or without binoculars:
Great Tit – Totally black head and neck with giant white cheek patches.
Great Tit – Wide black solid line from chin to underbelly in adults splitting the yellow breast in half.
Blue Tit – Light blue ‘cap’ on top of head – seperated by a white band around the head.
Blue Tit – Dark line running through the eye, with white feathers above and below it.

Obviously there are natural variations on this like juvenile Great tits don’t have the solid black chest line or bold white cheek patches, but still don’t have the dark eye stripe of the Blue tits.
What If It Looks Like A Great Tit But Isn’t Blue Or Yellow?
Coal tits are another common garden bird and can look a bit like both the Great and Blue tits, but for a few observable differences.
They have the same black head and large white cheek patches of the Great tit but have a seemingly longer flatter head giving them the appearance of having ‘no neck’. They do have a grey/blue back, but do not have a yellow chest at all, it is normally buff to brown.
