owl mail

No: HPFGUIDX 6992

I have a little question regarding the hunderd owls that swoop into 
the dining room every morning: Why do all these owls arrive at once? 
After all, people get owl mail every hour of the day and night 
anyway. 
I thought that maybe families that don't have owls of their own would 
send an owl in the morning from the post office. But that doesn't 
make sense, because the owls come from all over the place and it 
would take them different amounts of time to reach Hogwarts. [do you 
say that - 'differnt amounts of time'? I sometimes have trouble with 
colloquialisms.]
