This one was perched on\u00a0top of an upside down tumbleweed right next to the road. Short-eared Owl chicks leave the nest at the very tender age of 12-18 days and wander on foot until they fledge\u00a0(first flight) at about 27 days of\u00a0age &#8211; if\u00a0these siblings had actually fledged\u00a0they&#8217;d done so very recently. Neither of them\u00a0exhibited any fear at all of my pickup and that concerned me with them\u00a0so very\u00a0close to the road (so close that I couldn&#8217;t fit its virtual tail in the frame).<\/p>\n<p>These youngsters were both using parallax on\u00a0my pickup\u00a0&#8211; moving their heads, bobbing them\u00a0rhythmically from side to side, then forward, then back.\u00a0Sometimes their heads\u00a0were\u00a0almost completely upside down and during the entire performance they kept their eyes locked on me. Audubon describes the behavior as follows:<\/p>\n<ul>\n<li><em>&#8220;All these varied head movements help the owl judge the position and distance of things around it\u2014essentially, to triangulate on objects, including potential prey, and to build a composite picture of its surroundings. This head-bobbing helps make up for an anatomical limitation: An owl\u2019s eyes are fixed in position, so they simply can\u2019t move (in the skull)\u00a0the way our eyes do. To look up, down, or to the side, an owl has to move its head. They have very flexible necks and can do 270 degrees\u00a0of a full head turn, looking over one shoulder, around the back, and almost over the opposite shoulder. And after a few of these head-bobs to triangulate on their prey, they rarely miss.&#8221;<\/em><\/li>\n<\/ul>\n<p>Interpreting the results of parallax takes learning and practice so very young owls do it much more often than adults.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"59527\" data-permalink=\"https:\/\/featheredphotography.com\/blog\/2018\/05\/25\/sibling-short-eared-owl-chicks\/short-eared-owl-5363b-ron-dudley\/\" data-orig-file=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/05\/short-eared-owl-5363b-ron-dudley.jpg\" data-orig-size=\"679,900\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;7.1&quot;,&quot;credit&quot;:&quot;Ron Dudley&quot;,&quot;camera&quot;:&quot;Canon EOS 7D Mark II&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;1464591996&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;500&quot;,&quot;iso&quot;:&quot;400&quot;,&quot;shutter_speed&quot;:&quot;0.0005&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;1&quot;}\" data-image-title=\"short-eared owl 5363b ron dudley\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/05\/short-eared-owl-5363b-ron-dudley.jpg\" class=\"aligncenter wp-image-59527 size-full\" title=\"short-eared-owl-5363b-ron-dudley\" src=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/05\/short-eared-owl-5363b-ron-dudley.jpg\" alt=\"\" width=\"679\" height=\"900\" srcset=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/05\/short-eared-owl-5363b-ron-dudley.jpg 679w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/05\/short-eared-owl-5363b-ron-dudley-226x300.jpg 226w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/05\/short-eared-owl-5363b-ron-dudley-113x150.jpg 113w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/05\/short-eared-owl-5363b-ron-dudley-400x530.jpg 400w\" sizes=\"auto, (max-width: 679px) 100vw, 679px\" \/><em>1\/2000, f\/7.1, ISO 400, Canon 7D Mark II, Canon EF 500mm f\/4L IS II USM, not baited, set up or called in<\/em><\/p>\n<p>The other youngster was only a few feet away on a pile of dirt and at a steeper angle to me.
