The mystery and wonder of migration

As far as many of our birds and insects are concerned, autumn is here and the urge to produce young is replaced by an urge to migrate to winter quarters. Unlike during spring migration, when birds are in a hurry to get back to breeding grounds (before a rival takes over!) the autumn migration is an altogether more relaxed affair.

Someone mentioned in another forum about a willow warbler in their garden. There is every chance that it may linger for a while, if it can find sufficient food in the area. During autumn migration, many insectivorous birds, such as the warblers, will switch their diet and can often be found feeding on ripening berries.

Now is the time of year when many warblers can be found in atypical habitats, so look out for reed warblers in the tops of trees, and garden warblers feeding on elderberries in hedgerows.

Other birds, such as swifts have already moved out en masse, with birds now moving through in smaller numbers. Soon swallows and house martins will join the exodus.

As our breeding birds depart, birds that over-winter here will soon be arriving: fieldfares and redwings should make an appearance from the end of September, followed by many species of finch and waterbirds.

So, if you've noticed new arrivals or departures in your garden or local area, or have any questions about migration, this is the place to let us know.
