the swallows , house martins sand martins and swifts have gone from our base here on the welsh border , i think its early this year !!!! hope they come back... the willow wren chiffchaff and spotted fly catcher are still here . the robin who sings all year round is singing his autum song !!. would the swallows etc have stayed longer if there is an indian summer coming , do they know something we don t know ??? has anyone else noticed an early migration this year ??
