Hi

ok, so I was outside and with my chippies and they are both playing on their wheels.. when I hear a Strimmer going off about 2 houses down.. well both my chippies went quiet and was fasinated by the sound of this and was comming up to the front of their enclosure and was listening in...
then, one of my males (both males btw) started chirping, only a couple of sounds... ive never heard them before, was quite a shock..

then as the strimmer was going you could hear a faint squeek it was making (like if it needed oiling...lol) well the chippies were listening intensly by it all.
anyone know why? and why the chirping?
