Again I was disappointed, this time by all the clutter in front of the bird, but I still think the photo is interesting for a reason you&#8217;ve probably already noticed.<\/p>\n<p>Just look how ratty many of this bird&#8217;s flight feathers are. In contrast to the previous heron this bird is in the midst of a substantial molt. I remember that when I first started photographing birds I thought if I found a molting bird it meant that all other birds of the same species in that area must be molting too. There are too many variables to go into here but that&#8217;s not necessarily the case.<\/p>\n<p>I got some other shots I like of both birds in flight but for now I&#8217;ll focus on one more photo of this &#8220;ratty&#8221; heron.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"73960\" data-permalink=\"https:\/\/featheredphotography.com\/blog\/2019\/07\/29\/two-great-blue-herons-tweedledum-and-tweedledee-not-quite\/great-blue-heron-3384b-ron-dudley\/\" data-orig-file=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2019\/07\/great-blue-heron-3384b-ron-dudley.jpg\" data-orig-size=\"900,643\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;6.3&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;1564304961&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;700&quot;,&quot;iso&quot;:&quot;800&quot;,&quot;shutter_speed&quot;:&quot;0.000125&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;1&quot;}\" data-image-title=\"great blue heron 3384b ron dudley\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2019\/07\/great-blue-heron-3384b-ron-dudley.jpg\" class=\"aligncenter wp-image-73960 size-full\" title=\"great-blue-heron-3384b-ron-dudley\" src=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2019\/07\/great-blue-heron-3384b-ron-dudley.jpg\" alt=\"\" width=\"900\" height=\"643\" srcset=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2019\/07\/great-blue-heron-3384b-ron-dudley.jpg 900w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2019\/07\/great-blue-heron-3384b-ron-dudley-300x214.jpg 300w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2019\/07\/great-blue-heron-3384b-ron-dudley-768x549.jpg 768w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2019\/07\/great-blue-heron-3384b-ron-dudley-150x107.jpg 150w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2019\/07\/great-blue-heron-3384b-ron-dudley-400x286.jpg 400w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><\/p>\n<p style=\"text-align: center;\"><em>1\/8000, f\/6.3, ISO 800, Canon 7D Mark II, Canon EF 500mm f\/4L IS II USM + EF 1.4 III Extender, not baited, set up or called in<\/em><\/p>\n<p>Four frames later in the burst I got this shot of the heron in flight with the eroded creek bed in the background.<\/p>\n<p>Personally I think this is a pretty neat shot for several reasons but one of them jumps out at me. Can you guess what grabs my eye in particular? Keep in mind that I can be a little quirky when it comes to my photos&#8230;<\/p>\n<p>Just look how symmetrical this bird&#8217;s molt pattern is. I happened to time this shot just right so we can see through the &#8220;molt gaps&#8221; in both wings to the eroded creek bed behind the bird. Most bird species (there are exceptions &#8211; penguins and some others) molt their flight feathers symmetrically and gradually so they can more easily maintain balance in flight.<\/p>\n<p>Anyway, timing this shot as I did tickles me so I decided to include it. At this stage of my life I&#8217;m probably easily tickled.<\/p>\n<p>Ron<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>These two herons looked identical to me, until they took off.<\/p>\n<p> <a class=\"continue-reading-link\" href=\"https:\/\/featheredphotography.com\/blog\/2019\/07\/29\/two-great-blue-herons-tweedledum-and-tweedledee-not-quite\/\"><span>Continue reading<\/span><i class=\"crycon-right-dir\"><\/i><\/a> <\/p>\n","protected":false},"author":2,"featured_media":73960,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2},"jetpack_post_was_ever_published":false},"categories":[334,1094],"tags":[1095,712,4641,4642,311],"class_list":["post-73951","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-birds","category-great-blue-herons","tag-ardea-herodias","tag-great-blue-heron","tag-molting-patterns","tag-symmetrical-molting","tag-utah-2"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2019\/07\/great-blue-heron-3384b-ron-dudley.jpg","jetpack_shortlink":"https:\/\/wp.me\/p1zzJh-jeL","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/posts\/73951","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/comments?post=73951"}],"version-history":[{"count":0,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/posts\/73951\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/media\/73960"}],"wp:attachment":[{"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/media?parent=73951"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/categories?post=73951"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/tags?post=73951"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
