I saw this cormorant drying its wings on the Grand Canal near Clondalkin. I was delighted to see it so close. – Patricia Clarke, Cherry Orchard, Dublin 10

As I finished a walk on the side of Slievenamon, a red squirrel came bounding through the bracken pursued by a pine marten. The squirrel scrambled up a tree to the smallest limb, the pine marten climbed in the ivy on the tree trunk. A stand-off ensued about 60ft up, the squirrel making a “chut-chut” sound while the pursuer had a deep “murr”. – Joe Burke, Fethard, Co Tipperary

The smaller branch would not support the pine marten.
