Ducks in my street

Hi everyone,

A group of 4 Mallards, 3 male & 1 female turned up on my street about an hour ago. I'm concerned because they're at the entrance, close to the main road. I'm not sure what to do. I don't want them getting spooked and ending up in the road. Is there anyone I can phone, or will they just find their way back to where they came from?

Many thanks,

Lorna
