 Another way to tell the difference between Downy and Hairy Woodpeckers is to look at their tail feathers. The Downy has bars or spots on the feathers, whereas the Hairy doesn't.

This method isn't very useful if you can't see the white tail feathers clearly , though.

THANKS spottedowl. That will be a huge help for me identifying them in my yard. I can't always get a picture that would show the tail feathers clearly, but it gives me something to at least look for when I'm watching them.

actually, according to my books, hairy can also have the black bars....

actually i dont believe that... none of my other books say the hairy will have spots/bars on thier tails....Sibleys is less accurate than i would like it to be, cuz i rely on it alot...maybe i shouldnt... what  does everyone else think ?

 

I've found that Sibley's is mostly  accurate, but I prefer to use my National Geographic Guide. I think that the pictures are too small in Sibley's and the descriptions can be a little confusing.  The Hairy definitely  doesn't have the bars/ spots ( I know from reading and experience)

I've found that IDying Hairy/Downy by tail is extremely difficult as very rarely do you get to see the tail, though if you have pictures then the tail can be helpful and often times at feeders you can see it clearly, but what do you do if you have a worn Downy that has no bars (or only very faint) on the tail?  I've found that bill size is the way to go no matter what. What I do is mentally "remove" the bill and place it beside the birds head, Hairys will have a huge bill, approximately the length of the head, where as Downy will barely cover half. Always remember, Downy is dinky (and have dinky bills) and Hairy is huge (and have huge bills).

 

Hope this helps!

As I said earlier, this isn't always the best or most practical method. It does often work when you can see it clearly. Downys and Hairys  can be sometimes difficult to id even by looking at the bill or size, especially if you don't see the two species standing next to each other. Also , Hairy Woodpeckers have much variation depending  on which region you live in. I meant that this can be helpful when you can see the tail and are not sure about the size. I agree that the General Impression of Size and Shape birding method is important in this case.

Yeah it definitely is helpful when you see the tail, but when you can't see it you got to use something eles. Size is not very helpful at all, but bill size is like I said previously. You don't have to see the two sitting next to each other to judge bill size.

You are right about bill size.

ok,...now Sibleys and National Geographics Complete  Birds of North America state ( i can't quote,  illegal you know)..Hairies may show black spots on the outer tail feathers! and some downy may lack them! they state the best  ruler is the bill to head comparison. Not the tail spots or lack thereof
