Found on reclaimed land behind a factory, very close to a (big) river. The factory has very tall structures and chimnies, and for several years Perigrine Falcons can regularly be seen there. Also Kestrels nest every year... About 8 years ago a Gyrfalcon also stayed for a short while. Occasionally White Tailed Sea Eagles can also be seen flying over. This feather is 28.5 cm long, It is not from a Perigrine Falcon, Gyrfalcon, or Kestrel. Not from a White Tailed Eagle either. What could it be???! Photos show the same feather, the outter side and inner side, There are faint markings towards the top which could be 'stripes', (seen better on the inner side.) Could be a bird connected to the river rather than a 'bird of prey'. (Maybe?)

Im not sure,maybe can it be from this eagle?

Thank you for your replies... Colours and 'pattern' are a good match! Just a question : This feather is 28.5cm long. Given the shape of the feather and therefore its position in the wing, isn't 28.5cm too small for an Imperial Eagle???

Maybe young eagle,i saw adults flying near smaller birds and i suppose their were young eagles learning to fly,also,i saw them in the ground and theyre quite smaller than the adults (If i had mistakes,i dont speak english)

It is one of the inner primaries like p3. P6/p7 are much longer! So, yes it does fit to impereal eagle
