During the Autumn season, fungi can be seen in abundance if you know where to look. This Boletus is an edible variety, but I would not choose this specimen as it is growing in an area where I know there has been spraying of weed killer.
Another clear sign of Autumn is when the normally absent summer birds appear on the bird feeders as natural food is getting a little scarce. I love to see the Long Tailed Tits in the garden at this time of year. The Goldfinches will soon be back.
Rose Bay Willowherb is shedding its fairy seeds. These seeds will spread this annoying weed across gardens and farmland countrywide. It is a plant that will sucessfully colonise any bare ground.
Of course, the classic sign of Autumn is the leaf fall. We will soon be kicking leaves around the street again (and imported Christmas goods will soon be in all of the shops!).
