I've been listening to this descending whistling in my garden for weeks and been really puzzled. I've come to the conclusion its definitely coming from the oak trees in the field behind our house and can only assume it's a bird. Does anyone know what bird it might be? (ignore the rustling noises and the crows in the background!)

For me, the clip isn't long enough, though I can just make out two very short chirps, my guess, yes a bird.
Have a browse of the Bird Songs and Calls link below, whilst its not exhaustive, it may help point you in he right direction. The webpage lists quite a large number of birds and where possible, all the different types of call each will make. For some, you could have six or so different calls easily, ranging from alarm calls, through to song and many other types of calling.
