I've had a small 'wildlife' pond in my garden for a few years now.
It only measures about four feet by three feet, a lot of shallow area, and probably about two feet at its deepest part.
The birds love to bathe and drink from it, and at this time of the year, it plays host to a frog invasion.
I say invasion, but they are probably in the garden all year; it's just that at this time of the year, they are very visible........and very vocal.
I think they are a great addition to any garden, especially as a lot of their natural habitat is being lost to development.
A small garden pond is something most of us with a garden can do. It not only helps some of the local wildlife, it can sometimes be the life line some animals need.
One 'croak' I love to hear about.
