Ruby-crowned Kinglet

From USFWS_Pacific Region:

It may take years to see it, but when you do it's amazing! 

We're talking about the crown on a Ruby-crowned Kinglet. These tiny and cute #birds are moving down in elevation this time of year. They have a distinctive song that builds to an incredibly loud ending when you consider how small these birds are, so you might hear one before you see it.
