Garden humour – putting a nesting box for robins
Cartoon showing a gardener putting a bird box in a tree to encourage birds to nest in his garden
The joke is in the fact that there’s a robin building a nest in the packaging or packing box that held the nesting box kit rather than in the nesting box itself.
Robins are well known for building their nests in unusual places, such as in discarded kettles, tin cans etc.
