[sci.bio] Early birds

I am not sure whether anyone of you have had such encounters but recently, I
discovered that birds would start to sing and chirp as early as three hours
before dawn! They are definitely not owls and would gather in flocks on the   
trees. It is usually still too dark for me to see them and the singing would
stop about an hour before dawn. I do not recognise the singing and therefore
can't identify them. 

Is it normal for birds (excluding nocturnal ones) to be active so early in the
day? Has it something to do with the geographical location (I am living in 
Melbourne, Australia)?

I have heard mockingbirds singing at all hours of the day and night,
including midnight to 3 AM, but they seem to be usually solitary or in
pairs.  I love listening to mockingbird song, it is far more varied
than other bird song, and includes many different patterns.

Their behavior is unusual, too. I have seen them dive-bombing a cat
walking along the top of a fence.  They like to tease it and stay just
out of its reach, making the cat very angry.

The ones I have seen are medium sized and grey with dark bars on the
underside of the wings.  I don't know if their habitat includes
Australia.

Is there any street lighting? Here in sunny London, (and elsewhere in
the UK), robins, in particular, can often be heard singing in the
small hours, in areas with street lighting.

Here in Ohio mockingbirds (the male) seranade their mates all night.  Lovely
sounds in the pale moonlight....

My roosters crow every night at various times.  They do crow at dawn but
also at 1, 3, 5, etc.
