ternblack-headed gulls
A MAYFLY on the windowsill bends its abdomen from side to side. Perhaps this is a female releasing a scent message of pheromones to attract the males. This species has two long thin tails.

In the valley a tern dives for fish on the canal while a Black-headed Gull swoops down onto the river, apparently to pick up some floating food item.
