Fieldfare
Nils Paakkonen was probably right, my new neighbors outside the office window is a pair of Fieldfares.
This morning the whole family was at the nest:

First day with BirdCam
Last Friday I heard some strange noises outside my office window. To my big surprise I then noticed that there was a bird’s nest growing on the window sill. It did not take long until I even saw the new tenant moving in:
So far I have identified the birds as Song thrushs and the nest was steadily growing until about lunch time. After lunch no bird returned and I was almost afraid that something might have scared them off. However, I still planned to install a webcam to watch the nest during the coming weeks.
In the evening I set up a left-over Raspberry Pi Model A and an simple USB webcam. It’s running Raspbian Jessie and fswebcam and curl using a cron-ed script file. The camera itself is duct-taped to the inside of my office window.
