Proof that it is definitely autumn is the appearance of a delicate toadstool on the lawn.
At the same time all sorts of hips and berries are turning bright red, keeping colour going even though many flowers are fading.
Different birds seem to like different berries. There was a time, in a previous garden, where greenfinches used to gorge on the rose hips. The best we can do is provide food and see what does or does not turn up. Our pears are very popular with foxes, which certainly pick off what they can reach, night after night. This reinforces the message not to use pesticides. I have this year put a barrier of netting round the small plum tree, which seems to have worked. Last year small branches were broken off!
I have recently finished digging over a small patch of lawn to make a flower bed. I was very pleased to discover plenty of centipedes. On the relevant RHS web page one of the first things it says is: "Part of a healthy garden eco-system". Their main food is the sort of bugs that eat your plants.
The bird-life in the garden is moving on away from the spring and summer pattern. In that last week I have seen the first robin and the first coal tit noticed since April. There's lots to see if you look. Meanwhile I am not sure if the baby frogs have left the pond and immediately found excellent hiding places; I hope so.
