I'm not much of a bird photographer. But when a whole flock of allied Bohemian waxwing and fieldfares ransakes our rowan tree right outside our kitchen window I just had to bring the SMC Pentax-DA 55-300mm and try it out on these brave birds. Some images are not top sharp, which may partly be ibecause I was shooting in the upper end of the 300mm range, but may also be blamed on inpurities in the window glass (if I had tried to open the window they would all have gone in a flash).
It took them less than an hour to plunder the tree. When they left there were not more than a handfull of rowan berries on this pretty large tree. The winter have been hard and long and 60cm snow depth does not leave much for them to eat besides what are still on the trees. We have put out some old apples for them now when the tree is empty, and some of the field fares have been there, but I haven't seen a single waxwing since they emptied the tree. Hopefully they found some other trees to harvest.
