In\u00a0the few\u00a0exceptions to that rule there&#8217;s a reversal of sex roles where the males tend to the nest instead of the\u00a0females &#8211; phalaropes are one example of that. But in sexually dimorphic Belted Kingfishers the\u00a0bright rusty-red belt across the lower breast of the female makes her more colorful than the male who lacks it\u00a0but there&#8217;s no sex role reversal. What&#8217;s going on?<\/p>\n<p style=\"text-align: left;\">It may be explained in combination\u00a0with\u00a0yet another quirky trait of the species. Belted Kingfishers are highly territorial and the males often (though not always)\u00a0remain on their territories year-round so they don&#8217;t give up prime nesting territory and have to compete for it again in the spring. The females, on the other hand, migrate south for the winter.<\/p>\n<p style=\"text-align: left;\">So one theory suggests the female is more colorful as a visual signal to a resident male that he should welcome a returning kingfisher with a rusty-red belt in the spring instead of chasing her off. But researchers admit they don&#8217;t know that for sure and suggest\u00a0further research is needed.<\/p>\n<p style=\"text-align: left;\">Whatever the explanation &#8220;my&#8221; female will likely be gone soon so I&#8217;ll probably be making many more trips down the hill to the pond before she departs.<\/p>\n<p style=\"text-align: left;\"><em>Ron<\/em><\/p>\n<p><em>Note: I should make it clear that female kingfishers in regions that are less cold often\u00a0don&#8217;t migrate.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This female Belted Kingfisher continues to taunt me<\/p>\n<p> <a class=\"continue-reading-link\" href=\"https:\/\/featheredphotography.com\/blog\/2016\/10\/01\/belted-kingfishers-and-a-poorly-understood-example-of-sexual-dimorphism\/\"><span>Continue reading<\/span><i class=\"crycon-right-dir\"><\/i><\/a> <\/p>\n","protected":false},"author":2,"featured_media":42476,"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":[2853,334,391],"tags":[2329,916,2330,866,3136,276],"class_list":["post-42475","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-belted-kingfishers","category-birds","category-nesting-and-mating","tag-belted-kingfisher","tag-composition","tag-megaceryle-alcyon","tag-migration","tag-sex-role-reversal","tag-sexual-dimorphism"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2016\/09\/belted-kingfisher-6739-ron-dudley.jpg","jetpack_shortlink":"https:\/\/wp.me\/p1zzJh-b35","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/posts\/42475","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=42475"}],"version-history":[{"count":0,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/posts\/42475\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/media\/42476"}],"wp:attachment":[{"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/media?parent=42475"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/categories?post=42475"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/tags?post=42475"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
