Where, how to submit an amateur photo of wildlife

[HawkShot]

I have a spectacular picture of a hawk with a squirrel in its talons.
The picture was taken a moment after the hawk had flown out of a
cherry blossom tree. How can I submit this photo to a magazine?
Should I contact magazine companies directly? Any help would be
appreciated.
Thank you.
