I think there might be a couple of errors or at least alternatives:

> Martyn Hawkes

What about Hobby which regularly preys on swifts and swallows.

> Fursekytte literally, fierce kite

Could be Merlin since Furse or Furze refers to gorse and so
heathland - but in that case this also might refer to nightjar.

> Kyte: Black Kite (Milvus migrans)

Very, very unlikely. Red Kite was once common all over merry old
England and birds were common scavengers in London.
