The sound of fireworks exploding all around Hamilton last night (1.1mb, mp3).
Some nocturnal fox screaming.
A large group of seagulls started making a lot of noise in the carpark at work. A young bird had fallen under a car and the rest were trying to scare people away. (1m 30s, MP3)
The thunder rumbled on for pretty much the whole of the afternoon.
Some early morning birdsong. Recorded with the AudioShare iPhone app.
