At the beginning of April, during a sound recording trip, I accidentally came across a roost of Common Starlings Sturnus v. vulgaris consisting of several hundreds of individuals. During the morning recording session I realised that those songs were differently from those uttered at night. At night the birds arriving at the roost and and look for a suitable corner to sleep. Whilst doing this they territorial songs whereas in the morning one can hear birds uttering social or conversational songs all together.
