This immature male Kestrel has been causing some consternation with visiting birders as it has already grown three new black-tipped grey tail feathers, two of which protrude further than the others. It has also been remarked by several people that it appears bigger and bulkier than a 'normal' Kestrel.
Perhaps he felt like he could take on Fred Roll on this particular day given the beady look in his eye?!
The alula is clearly visible in this shot.

"The alula, or *** wing, is a small projection on the anterior edge of the wing of modern (and some ancient) birds." From Wikipedia,
For those of us who had no idea what an alula was!
Really difficult to get the exposure right for the underneath of a bird in flight isn't it?
