    Default Request for photo:Bird in flight or landing with feathers on upper surface "pop up".

    Erm...not sure if this will sound weird or very unreasonable here, but I have tried searching through flickr and pbase without much success, so thought maybe I can try asking here.

    I am currently doing a school project on the effect of self-activated flaps on a tiny airplane. This self activated flaps are actually inspired by birds, where their feather pop up during the landing approach to increase the lift at slower airspeed.

    Some example are:

    http://www.jrcompton.com/photos/The_...g-JR1_1355.jpg

    As this project requires a submission of poster summarising the findings which will be printed in relatively large size, I need a photo of decent resolution. So I am hoping that maybe someone here might have a photo like the above in higher resolution.

    I am willing to provide any details you need to assure you that this is solely for school project and not in any way commercial.

    Can anyone share one such photo, please?

    Are you referring to the alula? If so, there are plenty of photos available.

    TBH, I don't really know the biology name for that part, but it is this feather that is pointed by the arrow, the few extra feathers that pops up when the bird is landing...

    I am looking for a photo like this, just a bit higher res and with colour.

    Can anyone help please?

    Those are the covert feathers functioning as "eddy flaps".

    I'm sure there are high resolution photos of the "eddy flaps" in action so long as you take your time to search for it never the less here's a powerpoint presentation that might help in your school project.
