After yesterday, we needed to try harder.
So we headed to the shops to buy a sandwich tray. . . . . A bit weird, but stick with me!
Using sand from our old sandpit, we put a shallow layer in the bottom of the tray.
We spread it out thinly, then placed our bird food in the middle.
Hopefully when we have some visitors they will leave footprints.
If the sand doesn't work we might try compost with some water, yes a mud pie!
