I didn’t sleep well last night, no particular reason it just happens sometimes, one consequence of this was that I was awake when the first bird started to sing. At 03:27 a robin (Erithacus rubecula) started singing followed by another robin at 03:34, the first blackbird (Turdus merula) to sing a little after 04:00 (did quite catch the time). That last one I identified was a chaffinch (Fringilla coelebs) at 04:57, after that I drifted off to sleep until my alarm went off just before 07:00. The thing that strikes me most is that the chaffinch was the closes one to the sun rise at 04:53, it interesting that they started so early, by the time my alarm went off most of the singing had stopped. Could it be that they start early to avoid competing with the noise of the rush hour traffic?
