Joe, thank you so much
Trev, thank you very much; i am not sure what you were referring to
John, thank you so much
Izzie, thank you very much; that image was shot from the premises of a nearby railway station, through which i pass every week; a large collection of birds come to that tree, spend about twenty minutes there and disperse to roost there after. I was using canon sx 50 HS; since the light was low, the image was dark; so i had to process... one more silhouetted image from there....
Regards
