In response to Hugo Phoillips RFI on nocturnal Raven behaviour I have noticed 
the following.

Living in the inner Melbourne (Victoria, Australia) suburb of Richmond I 
see Ravens utilising a large gum in the back yard of a neighbouring property.  
The group of up to 25 birds arrives within about half an hour of dusk, usually 
silently.  The birds quickly find a 'preferred' roosting spot which is often in 
of eucalypt leaves high in the tree.

After nightfall the black birds are almost impossible to see in the tree but 
Flying Foxes (large fruit bats from the Royal Botanic Gardens 2km away) can be 
observed (and heard) flying overhead on their way to the greener suburbs along 
the Yarra River.  Next to this 'Raven roost tree' is a woodlot for firewood 
sometimes has its floodlights on at night.  Even though numerous moths and 
other insects are attracted to the lights, the Ravens have never been observed 
leaving their tree to catch them.  Not definitive evidence for Ravens being 
diurnal, but an observation on a group of these birds.
