As part of the ‘Making Wildlife Watching Easy’ series, here’s a nice simple wildbird guide: How to tell the difference between Rooks and Crows.
These 2 large black (and noisy) birds can be seen in both town and countryside. They are both quite heavy-looking and are often seen in groups – usually in trees. But although they look virtually identical from a distance, they have some very different features when you look more closely.
So, what are the key features to help tell them apart?
Well, the main differences are with the beaks, the legs and their habits – the easiest to spot is that the beak of the rook is larger, has 2 colours on it (black tip and cream toward the cheeks) and looks a bit scarier!
Once you can spot this – all the other differences aren’t important. However saying that, I still have a bit of trouble getting them to stand still so I can have a look!
And although pictures of them side by side can clearly show you the differences, when they are flapping about or up in the air – it really isn’t that easy first few times, so this is where you can use their behaviour to help you. Rooks are nearly always in large groups and rarely ever alone, whereas crows will often be solitary or in a small family group.
Visually, these are the main differences – and I have written them down only if they are clear differences rather than ‘a slightly rounder tail’, etc. These things should be clearly noticable with or without binoculars:
Rook – Pointy beak that has black tip and is exposed right to the eye.
Rook – Ruffled looking all over with noticable spikey head and untidy leg feathers.
Crow – Shorter, more curved beak which stops at the face and with feathers on top.
Crow – Neat rounded head feathers, with neat little ‘trousers’ at the top of the leg.
Obviously there are natural variations to both birds that you can only tell through experience – for example juvenile rooks are lacking the fully exposed beak and therefore they resemble a crow from a distance.
Jackdaws and Ravens are also black and really shouldn’t be confused with crows or rooks! Both are completely different sizes and it won’t take much looking to tell them apart.
Jackdaws are considerably smaller and have an almost silver sheen to their feathers and a clear black forehead that is easy to see when they land. They also have really bright yellow eyes! They are often seen with flocks of rooks so you can compare their size.

Ravens on the other hand are huge! If you saw a raven on the ground without any scale – it would look just like a crow – however, if seen next to known plants or other birds you won’t mistake them.
They are about the size of a herring gull where as crows aren’t much bigger than a magpie! They have over a meter wingspan in flight and an obvious wedge shape to the tail too.
