What time(s) do you see birds in your garden?

I find that most of the activity on my feeders happens between 10.30 and 12 - annoying as during the week I am at work at this time! I do sometimes see the odd blackbird or robin eating from the ground before I leave for work at 7.30/8, but not many and I never see birds on the feeders at this time. I never see birds feeding after work (4pm onwards). Is this normal or does it vary with location/time of year, etc?
