I very seldom see this species and I believe I&#8217;ve only photographed them once before\u00a0so I\u00a0was happy they made an appearance.<\/p>\n<p>I&#8217;ve often wondered how Northern Rough-winged Swallows acquired such an unusual name so this time I decided to do a little research. I&#8217;ll try to explain it\u00a0below\u00a0but doing it well\u00a0won&#8217;t be easy\u00a0because\u00a0the feature is too small to see\u00a0in my\u00a0photos and I couldn&#8217;t find an illustration or photo that I could legally\u00a0copy or even\u00a0link to. I\u00a0think you&#8217;ll\u00a0need to already\u00a0know some basic feather anatomy\u00a0to completely understand it but\u00a0let&#8217;s give it a shot anyway&#8230;<\/p>\n<ul>\n<li><em>The tiny stiff barbs of the leading edge of their outer primary wing feathers lack\u00a0terminal barbules between them\u00a0on their ends so\u00a0the barb ends\u00a0stick out all by themselves. In males those &#8220;pointy things&#8221; are recurved into tiny hooks but\u00a0in females they&#8217;re much straighter so they&#8217;re simply pointed. As a result, in males when\u00a0humans draw their\u00a0finger along the edge of the feather we feel\u00a0the\u00a0file-like roughness of those hooked barb ends. When early taxonomists had these birds in hand they were so taken with this characteristic that they referred\u00a0to it\u00a0twice when\u00a0assigning a scientific name to the species &#8211; their genus name Stelgidopteryx\u00a0means &#8220;scraper wing&#8221; and their species name serripennis\u00a0means &#8220;saw feather&#8221;.<\/em><\/li>\n<\/ul>\n<p>To this day the presumed\u00a0function of this unusual feature remains a mystery to science.<\/p>\n<p>Ron<\/p>\n<p><em>Addendum: This photo was taken a few years ago\u00a0on the only other occasion when I remember ever photographing this species. This bird and a\u00a0few others were nesting in a mud bank along the Jordan River.<\/em><\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"2685\" data-permalink=\"https:\/\/featheredphotography.com\/blog\/2011\/09\/02\/strategies-for-photographing-birds-at-take-off\/northern-rough-winged-swallow-1265\/\" data-orig-file=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2011\/09\/northern-rough-winged-swallow-1265.jpg\" data-orig-size=\"900,733\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;}\" data-image-title=\"northern-rough-winged-swallow-1265\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2011\/09\/northern-rough-winged-swallow-1265.jpg\" class=\"aligncenter size-full wp-image-2685\" src=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2011\/09\/northern-rough-winged-swallow-1265.jpg\" alt=\"northern-rough-winged-swallow-1265\" width=\"900\" height=\"733\" srcset=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2011\/09\/northern-rough-winged-swallow-1265.jpg 900w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2011\/09\/northern-rough-winged-swallow-1265-300x244.jpg 300w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2011\/09\/northern-rough-winged-swallow-1265-150x122.jpg 150w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2011\/09\/northern-rough-winged-swallow-1265-400x325.jpg 400w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Have you ever wondered how this swallow acquired such an unusual name?
