Birds singing in the spring forest

I recorded these birds singing in the forest last weekend in Belgium. It was a calm day, with some sun now and then and a few drops of rain. It seems like the birds never get tired from singing their songs all day. On the left there are some people talking in the distance, enjoying a walk in the spring forest.

After a minute a few drops come down from the leaves above me, but it doesn't really start to rain. This recording nicely illustrates my previous post Sound and levels of annoyance.
