How to Tell the Difference Between a Downy Woodpecker and a Hairy Woodpecker

While the little Downy Woodpeckers are very common at bird feeders, the shier Hairy Woodpeckers will come to feeders as well, and it can often be tricky to tell the difference between the two.

Here is a picture with a Hairy Woodpecker on the left and a Downy Woodpecker on the right:

The most immediate difference you can see is that Hairy Woodpeckers are much larger than the diminutive Downies.  When I first noticed the Hairy Woodpeckers coming to my feeder, my first thought was, 'Woah, that's a large Downy Woodpecker!'

Apart from their size, the easiest way to identify which is which is to look at their bill.  Hairy Woodpeckers have very long, chisel-shaped bills.  The bills are about as long as their head is wide.

The Downy Woodpecker, on the other hand, has a small bill.  It is only about 1/3 of the width of their head.  The Downy's bill also has a more noticeable downy tuft of nasal bristles around the base of it.

There are also a few subtle coloring differences: 

DOWNYHAIRY
NECK:
more rounded white patch
more uniform band of white
TAIL:
white outer tail feathers barred with black (looks spotted)
usually pure white outer tail feathers (at least in Eastern US)
BREAST:
subtle black mark on breast, if at all
distinctive black mark on breast



One more difference can be found with the male woodpeckers.  The males of both species have a red patch on the back of their head, but if there is a black line running through the middle of it, it is mostly likely a Hairy Woodpecker.

So think you know the difference between a Downy and a Hairy?
See if you can tell which is which in these pictures... some of them are tricky!

Ready for the answers?

Here they are, as well as some of the distinguishing marks in the pictures.

1. Downy - (you can see the small bill)
2. Hairy -  (large bill)
3. Downy -  (large, rounded white patches on back of neck and spotted tail feathers)
4. Hairy -  (the bill looks larger, there is a distinctive black mark extending onto breast, and the band of white at the neck looks like a narrow, uniform stripe as opposed to a rounded patch)

So how did you do?  It's definitely harder when they aren't on a bird feeder, so there's no relative frame of size!
