The heron had actually just landed after a very short flight of less than 10&#8242; from one spot on the riverbank to another. The cold wind was blowing fairly hard which I believe contributed to both the difficulty of the maneuver and to the amount of flaring of the wings and tail immediately after landing.<\/p>\n<p>I was just lucky to get a head turn that allowed us to see the heron&#8217;s face and eye (I believe this bird was looking at two other herons out of frame to the left.)<\/p>\n<p>I&#8217;m not particularly fond of the messy phragmites so close to the bird in the background and elsewhere but I&#8217;m almost mesmerized by how well the dorsal feather groups are displayed in good light. We can clearly differentiate each of the following groups and more:<\/p>\n<ul>\n<li><em>wing secondaries<\/em><\/li>\n<li><em>wing primaries<\/em><\/li>\n<li><em>greater secondary coverts<\/em><\/li>\n<li><em>median secondary coverts<\/em><\/li>\n<li><em>lesser secondary coverts<\/em><\/li>\n<li><em>greater primary coverts<\/em><\/li>\n<li><em>alulae<\/em><\/li>\n<li><em>scapulars<\/em><\/li>\n<li><em>tail feathers<\/em><\/li>\n<li><em>upper tail coverts<\/em><\/li>\n<\/ul>\n<p>I&#8217;ve photographed this and similar poses in other birds of course but I think the distinctive color patterns inherent in Great Blue Herons enhance and help to distinguish the feather groups from each other unusually well.<\/p>\n<p>It&#8217;s one thing to see all these feather groups beautifully illustrated in a painting or drawing in a field guide by someone like David Sibley but in my view it&#8217;s even better to see them clearly differentiated on a living, breathing bird.<\/p>\n<p>Even Sibley might agree.<\/p>\n<p>Ron<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A trip to Bear River MBR yesterday morning resulted in a single photo that strikes my fancy.<\/p>\n<p> <a class=\"continue-reading-link\" href=\"https:\/\/featheredphotography.com\/blog\/2020\/02\/10\/each-dorsal-feather-group-of-a-great-blue-heron-on-display\/\"><span>Continue reading<\/span><i class=\"crycon-right-dir\"><\/i><\/a> <\/p>\n","protected":false},"author":2,"featured_media":81560,"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":[338,334,1094],"tags":[1095,49,2618,945,712],"class_list":["post-81559","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-bear-river-migratory-bird-refuge-favorite-locations","category-birds","category-great-blue-herons","tag-ardea-herodias","tag-bear-river-migratory-bird-refuge","tag-david-sibley","tag-feather-groups","tag-great-blue-heron"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2020\/02\/great-blue-heron-9866-ron-dudley.jpg","jetpack_shortlink":"https:\/\/wp.me\/p1zzJh-ldt","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/posts\/81559","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=81559"}],"version-history":[{"count":0,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/posts\/81559\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/media\/81560"}],"wp:attachment":[{"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/media?parent=81559"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/categories?post=81559"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/tags?post=81559"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
