A bird typically poops around 50 times a day. Smaller species of birds tend to poop more often so it would not be unreasonable to say a small sparrow would poop more than 100 times a day
Just like us, humans (well, in most humans) birds do not poop while they sleep. They do wake up while they sleep to poop and then go back to sleep.
Since birds poop and pee from the same hole, the nighttime poops are primarily more liquidy and would be consistent with pee.
