But it happened yesterday at Bear River MBR with a couple of Great Blue Herons, seemingly on steroids.<\/p>\n<ul>\n<li><em>The following photos are documentary in nature and many of them leave a lot to be desired. The action was quick and unexpected and I was too close with the lens I was using to include both birds in most of the shots. In one series in all the excitement I had my lens severely tilted and I don&#8217;t have enough room in the frame to level the images. In addition I had bad luck &#8211; I was swapping my teleconverter on and off and even using another lens and camera combo at times but twice when the most crucial behaviors were going down I was fiddling with my gear so I missed those shots. And then when I got home I had a memory card malfunction and lost a few of my images (especially those that included both birds). <\/em><em>I know &#8211; excuses, excuses.

maintained for a few moments.<\/p>\n<p>I believe it was at this point that I made my fateful mistake. They were likely about to fight and there was no way I could keep both huge fighting birds in the frame with my long lens so I reached over to grab my smaller zoom lens. While I was fiddle-farting around with my gear they rushed at each other, skirmished briefly (I think, though I was looking mostly away when it happened), and then separated with the apparent loser flying off.<\/p>\n<p>I&#8217;ve seen Great Blue Herons displaying aggressively and fighting before but this ritualized, almost choreographed display was new to me so I did a little research on Cornell&#8217;s Birds of North America Online. What I saw in the field seems to closely match what BNA calls their &#8220;Upright and Spread Wing Display&#8221;. I&#8217;ve quoted BNA verbatim below:<\/p>\n<ul>\n<li><em>&#8220;The most spectacular display given by herons on the foraging grounds is the Upright and Spread Wing display that is given when two herons approach one another. The neck is nearly fully extended and tilted slightly over the back, the head and bill are held above the horizontal, and the wrists are drooped or held away from the body exposing the black shoulder patch of the adult. Sometimes the wing nearest the opponent is drooped lower than the opposite wing and the body plumes are erected. As opponents approach one another, the head and bill are raised closer to the vertical and the neck extended farther over the back. These displays usually cause the two herons to move apart but occasionally bring a chase. This display is sometimes directed towards gulls (Larus sp.), Great Egrets (Casmerodius albus), and even people.&#8221;<\/em><\/li>\n<\/ul>\n<p>I wish I could have a do-over with these herons so I could keep my teleconverter off of my big lens the entire time and so I&#8217;d know precisely when to switch to my smaller zoom lens but bird photography doesn&#8217;t work that way. I&#8217;ll have to be satisfied with experiencing the behavior and getting the photos I did.<\/p>\n<p>But I do wish I could just say &#8220;Take Two&#8221; like a movie director and have another go at it.<\/p>\n<p>Ron<\/p>\n<p>&nbsp;<\/p>\n<p><em>PS &#8211; I&#8217;d be interested in knowing if any of my readers have seen this precise behavior in Great Blue Herons.<\/em><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>After twelve years of photographing birds and paying particular attention to their behaviors it isn&#8217;t every day that I witness a ritualized aggressive behavior that&#8217;s new to me.
