Herring gull chicks test flights

All around my home there is the sound of demanding herring gull chicks as their are several nests nearby. I also keep a close on the nest, on the roof tops behind our bungalow, between the stacks of the chimney.

They have reared three chicks, perfectly camouflaged on the roof tops.

Today they have started to practice flight in earnest, leaping from the ridge of the roof and landing further down the tiles, before marching back up to the top and having another go.

As soon as one of the chicks start to exercise its wings, the parents go into defence mode, shouting at anyone or anything that come close.

Or dives on any potential intruder
