Well this is super-cute. Mr. and Mrs. Mallard find an out of the way place to raise their ducklings, but as the kids get a bit older they decide to move to the public garden. There's a lot of roads between the garden and their island home, and a lot of opportunity for squashed duckling, but thanks to a number of friendly policemen who clearly have nothing better to do than to stop traffic for wildlife, they all get there safely. It's kind and very mildly quirky, and the simple pencil drawings are both realistic and effective. I'd say it's a very old-fashioned type of picture book, but I remember a news article from the end of last year here in New Zealand, where police stopped cars on the Auckland motorway to let a family of ducklings cross, so good nature continues on much as it always has, I reckon.
