Wild Bird Wednesday 50 - Darter

 A few weeks ago I posted some cormorants, but choose not to include these pictures: I think this bird deserves a post to itself.

This is a male Darter (Anhinga melanogaster) also know as the Snake Bird, for its habit of swimming with only its neck out of the water.

The long neck - and remarkably large webbed feet - allow it to hunt fish underwater.  It actually uses its beak as spear and stab its prey rather then grabbing it with its beak.  An interesting aspect of this birds biology is the fact that it does not (cannot actually) waterproof its feathers with naturally produced oils. This means that the birds feathers become waterlogged as it swims.  This is good news as it helps the bird to sink and chase fish, but bad news because the feathers do not keep the bird warm underwater.  If you have ever watched a duck pop back up to the surface of a lake and seem the water bead off its feathers you will have seen how effective the oils can be at repelling water.

The long and the short of this means that Darters have to spend a lot of time drying their feathers - and warming back up again after the chill of swimming.  So the birds we see with their wings spread in classic "drying mode" it may actually be be soaking up some sun warmth after the chill of a morning spend fishing.

  4. Oh what a big mouth you have ... oh what a long neck you have ... OH what big feet you have ... All the better to .... to ...
    Well, he's really beautiful anyway, right in a homely sort of way. From the back in the last picture he really is beautiful. What a strange bird ... very much like the Cormorants, who also spend much time on the side drying their feathers. I love your blog ... you never cease to amaze me. And how about "50" weeks. Is that not awesome? I think you should design yourself a button to go with this meme. I think you are here to stay ... and I couldn't be happier for you.

  19. Your Darter or Snake Bird is cool, great shots. I like the webbed feet too. The Darter or Snake bird is another name for our Anhinga. Thanks for sharing and thank for hosting WBW. Have a happy week ahead!

  20. Great photos of the Darter I agree he needs his own post.

  21. Very aptly named and super pics Stewart.

    I have seen the American version but yours has a much more distinctive facial pattern.

  22. The top photo is a humorous catch. I do have to say that the oil on my face has never kept me warm. It only made my face break out.

  23. cool looknig bird, reminds me of an ahinga?

    ReplyDelete
  24. An impressive bird. I'd hate to be a fish on the end of that bill!

    ReplyDelete
  25. The pattern on the back of this bird are so unusual, and very pretty. What a unique beak, too.

    ReplyDelete
  26. Very interesting info Stewart. I would guess getting cold and being weighted down with the water is a good incentive to stab that fish as quickly as possible. :)
    A handsome bird and well captured with your camera!

  37. Hi Stewart ...I missed out on WBW had some troubles with internet!!
    I had to comment on this of your's because this bird made me giggle!
    Poor fella looks like he is made up of many different bird parts that just don't go together!!
    When my children where little (Many moons ago) we had a Little Golden Story Book named the "Churkengoose" my kids loved it!! He was part chicken, turkey, duck, and goose, this bird reminded me of it!! Hee-hee!!

  38. Amazingly large webbed feet (you captured them well) there Stewart and some amazing information about the drying out process this species has to undertake. Think I've only seen them in Africa where they are the Snakebird.

  39. Your Darter is quite similar in appearance and habits to our Anhinga. I enjoy watching them in the lake behind our Florida home, and am amazed at how large a fish they are able to swallow. Sorry I missed posting to Mr Linky the past couple of weeks but I was out of contact with the Internet during our RV camping trip in Arizona. Best wishes and hope to join you next Wednesday!
