Afternoon, a small bird hops in crackly leaves near the microphones, sirens pass by and shouts come from the sports field

Whilst listening to an audio stream one is not present and there is no visual information. I don't know which small bird is hopping in the leaves, only that there is one. There are some quiet, brief wren churrs so maybe it is him(or her). The little grebe continue to trill from the lake and a goshawk calls from the distance. The human city is more obvious with sirens, traffic and sports players.
