Lister Park 22/07/18 17 inc 10 chicks (3 broods:5 +3+2 First seen '18). Keighley Moor Reservoir 05/08/18 The family party with seven ducklings have disappeared - where and how is a complete mystery. There was a considerable amount of disturbance over the weekend at what is usually a very quiet remote site. It seems unlikely that all seven would have been predated, whenever they have been disturbed by the occasional dog walker they simply move away from the shore to the centre of the reservoir. There is no other body of water in the vicinity and I doubt the ducklings would have been able to fly.
