Going postal (bottom part of a feather)

Another abandoned feather, this time one of the younger kind, of a pigeon. Difficult to really focus sharp on one point though.
Under a small tripod with 3 soligor extension rings (12mm, 20mm, 36mm) stacked with a prime 1.8 50mm. If the pigeon was still attached to this feather (and not yet met its creator), you would not have seen this:)
