We have put out some bird seed, peanuts and fruit and it has increased the wildlife in our garden dramatically! We have had 3 different woodpigeons, 2 blackbirds, 2 squirrels, 2 blue tits (who have recently had chicks and they are all over the place), 2 collared doves, a wren, a robin and even a jay but he/she rarely turns up. The smaller birds love our waterfall for a little bath and a drink.
The woodpigeons are by far the most entertaining to watch though: enormous and clumsy!
And a quick look out the window and there is one there now!
