A hot, hot day at the start of this month. Two broods of ducklings which had been about the ifrst to hatch this year along the canal, now getting their adult feathers. The two groups were together – and all alive. To keep cool, they were playing. Doing all the thinks kids aren’t supposed to do at the swimming baths. Charging at each other. Power-diving, submerging only for a second. Shaking like a wet dog to dry off.
