Birds making 'orrible noises? (4)
I believe the answer is:
owls
I believe this is a double definition.
'birds' is the first definition.
(owl is a kind of bird)
''orrible noises?' is the second definition.
('howls' - horrible cries - said with a cockney accent, dropping the 'H', like 'horrible noises' was)
'making' acts as a link.
(Other definitions for owls that I've seen before include "Night birds" , "Types incredibly wise" , "Nocturnal birds" , "Slow sort of birds" , "Avian symbols of wisdom" .)
