I realized my error only minutes after publishing my post and even though I immediately added a note to the post acknowledging my mistake the damage was done. Making such a basic blunder is one of my biggest fears about blogging and bird ID isn&#8217;t my strongest point so I always try to be extra careful in that regard. But yesterday one slipped through the cracks.<\/p>\n<p>In a comment on that post bird authority Dan Gleason tried to make me feel a little better about my error with the following comment:<\/p>\n<ul>\n<li>&#8220;<em>Nashville and MacGillivray\u2019s Warblers are easily confused, especially as people are learning to ID their birds. By making this mistake and pointing out the complete, not broken eye ring of the Nashville, you\u2019ve called attention to this feature and provided a good aid, along with a great photo, to help others to distinguish these two species when they see them in the future. Mistakes can always be a helpful tool in learning<\/em>.&#8221;<\/li>\n<\/ul>\n<p>So today I decided to do the best job I could of turning a serious error made in a public forum into a more effective &#8216;learning tool.&#8221; The easiest way to distinguish between Nashville and MacGillivray&#8217;s Warblers is using the difference in their eye rings as a field mark. Yesterday I briefly described that difference but didn&#8217;t include photos of both species actually <em>showing<\/em> the difference..<\/p>\n<p>Since most of us learn best visually I&#8217;ll do that today.<\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"88969\" data-permalink=\"https:\/\/featheredphotography.com\/blog\/2020\/08\/27\/nashville-warbler-versus-macgillivrays-warbler\/nashville-warbler-1165-ron-dudley\/\" data-orig-file=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2020\/08\/nashville-warbler-1165-ron-dudley.jpg\" data-orig-size=\"900,643\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;5.6&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;1598343119&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=\"nashville warbler 1165 ron dudley\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2020\/08\/nashville-warbler-1165-ron-dudley.jpg\" class=\"aligncenter wp-image-88969 size-full\" title=\"nashville-warbler-1165-ron-dudley.\" src=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2020\/08\/nashville-warbler-1165-ron-dudley.jpg\" alt=\"\" width=\"900\" height=\"643\" srcset=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2020\/08\/nashville-warbler-1165-ron-dudley.jpg 900w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2020\/08\/nashville-warbler-1165-ron-dudley-300x214.jpg 300w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2020\/08\/nashville-warbler-1165-ron-dudley-768x549.jpg 768w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2020\/08\/nashville-warbler-1165-ron-dudley-150x107.jpg 150w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><\/p>\n<p style=\"text-align: left;\">This a different photo of the male Nashville Warbler I posted yesterday (initially I had mistakenly called him a female MacGillivray&#8217;s Warbler).

Males of this species have black lores (between the eye and the base of the bill) but the female lacks the black lores and both sexes can be confused with Nashville Warblers. Even Sibley says the two species are &#8220;often confused&#8221;.<\/p>\n<p>But notice that the eye ring of MacGillivray&#8217;s Warblers is &#8216;broken&#8217; or incomplete, to the point that the whites surrounding the eyes are often called &#8220;eye crescents&#8221; instead of eye rings. There are other more subtle differences between the two species but the eye ring difference is the most distinctive and I think the best field mark.<\/p>\n<p>I should have noticed that difference in yesterday&#8217;s post but I&#8230; just&#8230; didn&#8217;t. Hopefully today&#8217;s post will help all of us to better distinguish the two species.<\/p>\n<p>We all make mistakes but if I make the same mistake again just shoot me.<\/p>\n<p>Ron<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Trying to make lemonade out of an unusually sour lemon.<\/p>\n<p> <a class=\"continue-reading-link\" href=\"https:\/\/featheredphotography.com\/blog\/2020\/08\/27\/nashville-warbler-versus-macgillivrays-warbler\/\"><span>Continue reading<\/span><i class=\"crycon-right-dir\"><\/i><\/a> <\/p>\n","protected":false},"author":2,"featured_media":88968,"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":[334,5160,5307],"tags":[5310,679,5309,5161,5306,5308],"class_list":["post-88967","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-birds","category-macgillivrays-warblers","category-nashville-warblers","tag-complete-eye-ring","tag-field-marks","tag-incomplete-eye-ring","tag-macgillivrays-warbler","tag-nashville-warbler","tag-warbler-identification"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2020\/08\/macgillivrays-warbler-3119-ron-dudley.jpg","jetpack_shortlink":"https:\/\/wp.me\/p1zzJh-n8X","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/posts\/88967","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=88967"}],"version-history":[{"count":0,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/posts\/88967\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/media\/88968"}],"wp:attachment":[{"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/media?parent=88967"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/categories?post=88967"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/tags?post=88967"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
