Hello Steve!
At the beginning of the broadcast last season, there were a lot of noises that suggested construction work. Heavy construction work. So I thought this nest was close to the nest of H44 & H21. The construction of a new industrial building was announced there (which is why the stream was stopped). It was basically just confirmation, because we could already hear that massive construction work was underway. So the background noises from both nests were very similar last year.
I now know that the nests are 4-5 km apart.
I don't know what sometimes happens here. It's a hospital site. But there could be modernizations there too. Extensions to the building or improvements to a green area, etc.
Cleaning machines also seem to be driving through. Or there's construction going on nearby. Apartments, a supermarket...
Yes, sometimes it's really loud.
Interestingly, the pair isn't too bothered by it. Only sudden bangs, bangs, or clangs make them flinch and become briefly very alert.
They're more likely to react to nearby human voices. Specifically, children (in anger or sadness) and uneven tones. . They detect abd feel an uneasy mood.
These are things I notice but no longer document. It's very subjective, and it would also be too much of a stretch.
I've become so accustomed to the trains that I hardly hear them anymore. That just occurred to me.
Best regards, Polly
