Next up for raptors ... the Northern Harrier.
All pictures were taken last year in Minnesota and Wisconsin, but Northern Harriers are found throughout the northern hemisphere of the world.
Notice the face. They have facial discs that make them look similar to owls. This helps with hearing. It amplifies the sound, just like cupping your hands behind your own ears does.
They fly low, usually just above the cat tails and grasses, while listening and watching for smaller critters. They are also known as Marsh hawks, because marshland is their main habitat.
They rarely have to flap their wings. They can lazily glide low with their wings in a shallow V, rocking back and forth to provide lift. The Brits admire their flying capabilities so much that they name the Harrier jump jets after them. Not that unusual I guess because most jets are named after raptors.
Here is one flying away from me with a small squirrel.
The males are silver, white and black, with yellow eyes and feet. Takes them about 3 years to acquire their adult plumage. Females are brownish like the above ones.
If you see a big bird, gliding low over a marsh or field, rocking back and forth as it flies, and has a white spot on the top of the tail (rump), and you're in the northern hemisphere ... it's more than likey a Northern Harrier.
