Norma Price kindly sent us this local news item from a friend:
One of our school buses was brought in for a routine service, but a fault with a headlight was discovered and it had to be removed. Once it had been taken out of the bus, the mechanic discovered a nest built at the bottom of the lightwell. The nest had the remains of a blue egg in it, and we are assuming it was built last year. It was a Blackbirds egg.
We simply have no idea how a bird managed this. The bus was out and about every school day. In addition to actually getting in there, the bird had to go in under the bus, fly up between the radiator and the front grill, "take the first right", and then dive down under the lamp. Amazing stuff!
