Swallow feeding young

Recently purchased a secondhand Nikon 70-300mm zoom lens, however in my haste in purchasing said bargain I did not notice the fact that it was a manual focus lens. It is a hit and miss affair at the moment but i'm enjoying the extra reach that it affords me.

I enjoyed the challenge of photographing the Swallows feeding their young. There were six juveniles lined up waiting to be fed by the parents that were busy sweeping the adjacent fields.
