I've a question regarding the calls of these birds. I found a few warblers making a call that I understand to be typical of Eastern Bonelli's, a 'tzit' sound, nothing like the usual Chiffchaff call. Do Chiffchaffs have a similar less frequently used call though? Eastern Bonelli's is uncommon here so I don't want to be jumping to conclusions based on just a call and so I know for future reference. TIA.
