Hi Oscar,
On images like these, It is more appealing if you capture the bird flying towards you, not flying away from you...:D I lightened the background just a tad and sprinkled a wee bit of sharpening because the bird was a tiny bit on the soft side...hope you approve...:)
Great composition, as the bird really stands out. Birds usually fly away from me, too. Maybe someone will give a hint as to how to get them to fly towards you. :D
ditto the bird flying away from you - as for them flying towards you I think you need to have a look at Arties CD Book - I believe it has to do with wind direction. And the ability to get yourself ito known flighpaths, a place were you know the birds will return to and from. (Not that easy out here in OZ)
