The Sound Of The Rains

This Sunday it was raining in Brasília for the first time since mid May. Everyone have been waiting and asking for the rains to come, as it has been very dry, some days the humidity even went down below 10% which is extreme, less than in the desert. And the rains are supposed to come now, even though maybe only in October, people say September is early and it was only a rather short rain, one night.
But nevertheless you can tell the difference. Nature has only been waiting for the rains and it was so ready.
One thing that has changed too is also the sounds. The birds are even more lively and loud in the mornings. But the main new sound is something that I don't really know what it is yet. I would guess it is some kind of cricket, but it sounds different from the ones in Europe. It snarts with a little hesitant knacking sound but then increases to something absolutely not hesitant. It has a very lound, constant and long tone. You can here it from very far and you hear many at the same time. Very interesting, and a little annoying. But aparently it is a sure sign for more rain, people say.
