itemprop=\"text\" ><p>If you know much about the loggerhead shrike, and shrikes in general, you\u2019ll know the come by the nickname \u201cbutcherbird\u201d quite honestly. Shrike are \u201cperch and wait\u201d hunters, similar to raptors, but they lack the talons and strong feet of a raptor so instead, they \u201ccache\u201d or store prey that is too large for them to swallow on a thorn or piece of barbed wire.<\/p>\n<p>You would think that with their nickname being what it is, and given their habitat is full of hawthorns and barbed wire to spear things on, it would be quite common to see caches of dead animals bedecking the trees and fences like some kind of morbid holiday ornaments. However, in our entire season up to as recently as June 13th, we had seen not one piece of evidence that these birds cache food at all!<\/p>\n<p>Then, one lucky afternoon as we were monitoring at one of our nest sites and having one difficult time finding where the adult birds were foraging, one popped into a hawthorn not 100 m from our location with a long stringy thing pinched between its mandibles and dangling as it moved. What happened next was incredible: as we watched, the shrike moved to a dead hawthorn branch and began pushing the prey item (looking a bit worm like) onto a thorn.<\/p>\n<p>When viewed with the scope I could see the animal had belly scales, indicating it was a snake \u2013 albeit a small one \u2013 but a snake nonetheless!<\/p>\n<\/div><\/section>\n\n<\/div><\/div><\/div><!-- close content main div --><\/div><\/div><div id='av_section_3'  class='avia-section av-3k1p14w-8bb1e69886e0ce1dff250e48faa39e2e main_color avia-section-default avia-no-border-styling  avia-builder-el-7  el_after_av_section  el_before_av_section  species-inner-content-intro-wrapper avia-bg-style-scroll container_wrap fullsize'  ><div class='container av-section-cont-open' ><div class='template-page content  av-content-full alpha units'><div class='post-entry post-entry-type-page post-entry-18016'><div class='entry-content-wrapper clearfix'>\n<div  class='flex_column av-315057k-07842072ff86189d5d736b5987434d34 av_one_half  avia-builder-el-8  el_before_av_one_half  avia-builder-el-first  first flex_column_div'     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-lfk90u3z-90d9fa80945668a1cec838fe7443ca97\">\n.avia-image-container.av-lfk90u3z-90d9fa80945668a1cec838fe7443ca97 img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-lfk90u3z-90d9fa80945668a1cec838fe7443ca97 .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-lfk90u3z-90d9fa80945668a1cec838fe7443ca97 av-styling- avia-align-center  avia-builder-el-9  avia-builder-el-no-sibling'   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img fetchpriority=\"high\" class='wp-image-37310 avia-img-lazy-loading-not-37310 avia_image' src='https:\/\/wildlifepreservation.ca\/wp-content\/uploads\/2022\/07\/Web-screenshots-486x1080.jpg' alt='' title='Web-screenshots'  height=\"1080\" width=\"486\"  itemprop=\"thumbnailUrl\"  \/><\/div><\/div><\/div><\/div><div  class='flex_column av-2onsla8-1a40542b2f6e1dd279ee2dfce02af862 av_one_half  avia-builder-el-10  el_after_av_one_half  el_before_av_textblock  flex_column_div'     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-lfk91fwj-9f335ef60d6d74e991ae9ddb1a7c1d4a\">\n.avia-image-container.av-lfk91fwj-9f335ef60d6d74e991ae9ddb1a7c1d4a img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-lfk91fwj-9f335ef60d6d74e991ae9ddb1a7c1d4a .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-lfk91fwj-9f335ef60d6d74e991ae9ddb1a7c1d4a av-styling- avia-align-center  avia-builder-el-11  avia-builder-el-no-sibling'   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img fetchpriority=\"high\" class='wp-image-37309 avia-img-lazy-loading-not-37309 avia_image' src='https:\/\/wildlifepreservation.ca\/wp-content\/uploads\/2022\/07\/Screenshot_20220707-150127_Photos-1-486x1080.jpg' alt='' title='Screenshot_20220707-150127_Photos-1'  height=\"1080\" width=\"486\"  itemprop=\"thumbnailUrl\"  \/><\/div><\/div><\/div><\/div><section  class='av_textblock_section av-lfk93hhx-5390cd195c63c386a2685af9313714a3'   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p style=\"text-align: center;\"><em>An eastern loggerhead shrike impaling an eastern milksnake on a hawthorn tree.<\/em><\/p>\n<\/div><\/section>\n\n<\/div><\/div><\/div><!-- close content main div --><\/div><\/div><div id='av_section_4'  class='avia-section av-23laclc-f36c0c323328dcb38abfbcfc7ddbfd40 main_color avia-section-default avia-no-border-styling  avia-builder-el-13  el_after_av_section  el_before_av_section  species-inner-content-intro-wrapper avia-bg-style-scroll container_wrap fullsize'  ><div class='container av-section-cont-open' ><div class='template-page content  av-content-full alpha units'><div class='post-entry post-entry-type-page post-entry-18016'><div class='entry-content-wrapper clearfix'>\n<section  class='av_textblock_section av-1izg8u8-7d167f67b8cd8e98e8291bbb2251039d'   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p>After the shrike had pierced its prey on the thorn, it used its bill to bite, tear and swallow a piece (likely the head) off it before moving back to the nest tree. Once we were sure the bird was clear of the area we went to investigate the cache and found a headless eastern milksnake about 1 cm in diameter and 18 cm long dangling from the thorn.<\/p>\n<p>We could imagine how many feedings one snake could provide to tiny mouths at the nest and were so excited that we finally had found a cache and even better, watched the shrike in action making it! After snapping a picture, we headed out of the site reassured that the birds were still actively feeding young.<\/p>\n<p>This observation may have been a once-in-a-lifetime opportunity, and one we certainly do not take for granted.
