One of the cleaners brought my attention to a small bird at the tiered seating in hall 4. I went over with him and found the bird sitting still on the step, it was a Chiffchaff.

They winter in Africa and return to breed each summer, it would have been migrating through when it somehow found it's way in to hall 4. The bird was very weak and unfortunately died shortly after I picked it up.

This is only the second record of Chiffchaff on the site.
