Walking on water

I had planned to send these two photos to the Facebook page, The Worst Bird Photos Ever, but I think they may be interesting, so here they are.

Running takeoff

Hopping takeoff

Dabbling ducks, such as mallards, rely on their larger wings to take to the air almost vertically. The divers, such as these Harlequins, need to get up speed before they can fly. Loons are so slow that they may need up to a quarter mile (about 400 m.) to get airborne. I couldn't find distance requirements for harlequins.

Corriendo sobre el agua.

Había pensado mandar estas fotos al sitio "Las peores fotos de pájaros", pero creo que pueden ser interestantes, así que aquí están.

Las aves anatinas, que buscan su comida en aguas poco profundas, como por ejemplo el pato real, a causa de tener alas amplias, pueden despegarse de la superficie casi verticalmente. Las buceadoras, en cambio, tienen que alcanzar una cierta velocidad antes del despliege. Los colimbos pueden requerir hasta 400m antes de lanzarse al aire. No pude encontrar los requisitos para los arlequines, como los de estas fotos.

  1. I wonder if individuals "specialize" in one pattern or mix the two.

    1. It looks like there's a difference in the angle that these are starting from. I'll have to watch more. It's an interesting question!

If your comment is on a post older than a week, it will be held for moderation. Sorry about that, but spammers seem to love old posts!

Also, I have word verification on, because I found out that not only do I get spam without it, but it gets passed on to anyone commenting in that thread. Not cool!
