A Genetic Courting Strategy: The Ruff an Eurasian Shorebird

in #science6 years ago (edited)

In courtship some Ruffs are fighters, some are lovers, and a few are downright sneaky, its written in their genes.

Ruff

Ruffs are Eurasian shorebirds that breed in the wetlands across northern Europe and Asia. The patches of marshes were Ruffs breed are called leks.

Male Ruffs are larger than females and have a ruffed collar. Among all shorebirds the male Ruffs have the most spectacular plumage.

Scientist have found that male Ruffs are genetically divided into three types, independents, satellites, and faeders. Each type of male Ruff has its own courtship technique.

Independent Male Ruffs

Independent male Ruffs are 80% to 95% of the male populations of Ruffs. The independent males have fancy plumage and an appetite for fighting.

Satellite Male Ruffs

Satellite male Ruffs are 5% to 20% of the male population of Ruffs. The satellite males have a white collar. Although not as colorful as the independent male Ruffs, the satellite males display their feathers alongside the independents to help attract female Ruffs to the lek.

The independent male Ruffs tolerate the satellite males and occasionally allow the satellite males to mate.

Feader Male Ruffs

Feader male Ruffs are less than 1% of the male population of Ruffs. The feader males look like female Ruffs. Feader males don't have any colorful feathers and don't fight. The feader male Ruffs blend in and mingle with the female Ruffs. When a female Ruff indicates she is ready to mate, the feader Ruff sneaks in and mates with the female before the independent male.

Expanding your ornithological horizons, I see! Very strange and interesting species with 3 types of males with 3 different functions. Wondering why they have this diversity? Very interesting post.

Agreed the Ruff breeding behavior is pretty cool. Another species with cool genetic breeding weirdness is the White-throated Sparrow. @birdbanter posted on this yesterday. If you are interested in birds you might want to follow @birdersofsteem a site where birders can support each other and develop a community for birders here on #Steemit #birding

Thank you!

I am following @birdersofsteem and I will start using #birding in my blog posts about birds.

Have a great day and a fantastic week!
Steem on,

I think feader male population is much lesser tjan the other ones..i never seen this bird before.

Amazing..Post
Good work..

really good ... 👍

@etcmike I love the passion you feel to investigate exotic birds.

I remember that in my free time I liked watching documentaries of birds and animals.

In your blog you have made me aware of the existence of very beautiful birds, and also of others in danger of extinction.

Your article are really impressive and full of information. followed and upvoted!!
kindly visit my blog if you have time.

really amazing, sir. up vote it.

Awesome work... really interesting.
keep it up

Awesome pictures sir,i think its a rear bird.
