A Northern Harrier Kind Of Morning
Normally I avoid doing back to back posts on the same species but I went out shooting immediately after I published that last post and surprisingly it turned out to be a heckuva harrier morning. I’ve mentioned before that I usually have my best luck with harriers in the middle of winter, but yesterday I found two cooperative birds. 1/1600, f/6.3, ISO 500, 500 f/4, 1.4 tc, natural light, not baited, set up or called in This beauty was hunkered down for a break from hunting and let me get surprisingly close. It was early morning, the light was warm, and the bird posed for me for a long time. I chose to post this almost direct look from the hawk for a reason – because out of all those images, this one shows the unique harrier facial disc best.
