CHIFFCHAFFS NEAR AND FAR

I have good memories of the song of Spring, a chiffchaff singing,its not just the Cuckoo that heralds Spring.
 14th September to-day, the Cuckoo has long gone but the Chiffchaff remains.  Sometimes this birds sings Chiffchaff and other time specially during the Autumn its call is 'hweet'.
Again sometimes it bobs its tail, a sure sign that the bird is a Chiffchaff and not a Willow Warbler.  
Black legs another sign.  Little Spiders under leaves are part of their diet and this little warblers can hang upside down seeking out the small insects.
