Black-billed Magpie (Pica hudsonia)

Black-billed Magpie (Pica hudsonia) 

This magpie was seen crossing the road in the Rocky Mountain National Park. I love these birds because they are blueish and have really long tails, so they are fun to look at. These birds are only found it the west, and according to wiki, they are only one of four songbirds in North America who's tail makes up half or more of its body length. They construct really large nests, which you can see here. You can also read more about this bird here.
