I adore the distinctive Dzzweeeee sound that explodes out of those lovely little Greenfinches. I used to hear them most summer times at home and remember that it was my Dad who pointed them out to me. Every year we listened out for them and reported back to each other ''The Greenfinch are at it again" . Dzzweee...Dzzweee...Dzzweee...Dzzweee...Dzzweee. I hadn't heard them around for about 10 years and then, out of the blue... Dzzweee !
