Nature's calendar: September

September is a month of change with autumn rapidly taking hold but don’t worry, there’s lots to enjoy in the early autumn sunshine. Berries are all ripening and birds are well and truly on the move as migration is in full swing.

This month you're asking...

Migrant watch

  • Don't worry if your garden goes a little quiet in September. This month sees a glut of ripe fruit and seeds in our gardens and all around the countryside which birds will be making the most of.

  • Having said that, keep an eye on your berry bushes for some unusual visitors. Migration is in full flow meaning that birds can turn up anyway. Blackcaps are very partial to blackberries so keep an eye on an unmown corner of your garden which you leave to go a bit wild.

  • Capitalising on the abundance of dragonflies could be a hobby which migrate to Africa throughout September and like the dragonflies, could turn up wherever there is something to eat.

  • Look out for a rarity! September is the perfect time to come across a real surprise. Occasionally birds migrate the wrong direction or get caught out by winds meaning anything could turn up anywhere. A real treat this month would be an off-course wryneck which is a small member of the woodpecker family and loves looking for ants on paths and patches of bare ground.

Garden watch

  • We all love our garden robin but keep an eye out for multiple robins this month. These birds migrate and disperse widely so look out for disputes between your regular robin and a passer-by.

On your walks...

  • Eye to the skies to look out for our summer visitors heading south. Swallows and house martins will be on the move. At this time of year, you’d be surprised at what birds are migrating. Almost all our birds disperse or migrate in some way. Even the tiny wren is known to travel hundreds of miles during the autumn. Most birds you encounter during September will be on some sort of journey so keep that in mind as you walk around the countryside.


In your garden:

  • Some butterflies might unexpectedly appear indoors. These are likely to be small tortoiseshells or peacocks, looking for somewhere safe to hibernate for the winter. If the weather is warm and dry, best to pop them safely back outside or if the weather isn’t too good, in an outhouse or shed with access to the outside.

  • Autumnal moths. Moths often appear at lit windows throughout the year but have a closer look at this time of year and you’ll notice some very autumnal colours. Oranges, yellows and of course brown but they’re by no means boring. Canary-shouldered thorn or the pink-barred sallow are just some to look out for.

Out and about:

  • September sun will be tempting many insects to keep active and particularly migrant hawker dragonflies that can be abundant in September. These are not always found near water and will hunt almost anywhere for smaller insects to eat.

  • Crickets are at their loudest on a warm early September evening, particularly in the south. The loudest is the great green bush cricket which is also our largest! Is it a cricket or a grasshopper? Look at the antennae. Short on a grasshopper and very long on a cricket. Easy!

  • Hedgehogs will be busy feeding up as they’re very aware that it’ll soon be time to hibernate.

  • Fox wars! Cubs are now all grown up and leaving their dens to find new territories which could mean lots of disagreements in your neighbourhood.

Reptiles and Amphibians

  • This month could be your last chance to enjoy your garden pond wildlife as the water temperature starts to drop. Frogs and newts may be thinking of heading out of the pond for the winter, but the insect life can still be abundant on a sunny day with pond skaters and whirligig beetles making the most of the autumn sunshine.
  • Cooler nights mean you have a better chance of seeing reptiles basking in the morning and late day sun. Look out for sunny spots near cover for grass snakes or adders basking or check sunlit rocks or logs for common lizards.


  • Hedgerows are changing colour and usually red means danger but not for birds at this time of year. Hawthorn and rowan berries are now perfectly ripe and tasty, and birds love them.
