Can anyone please help with any information about the two variant songs I have recently recorded of the chiffchaff singing? I know that the normal chiffchaff song is often made up of an irregular pattern of ‘chiffs’ and ‘chaffs’ but these variants are very different notes that are produced in the intervals between the normal bouts of singing. They are much quieter; perhaps that is why I have never noticed them before and they could also easily be mistaken for bird vocalisations.
