wot value

Hi All,

          Being allowed to do your birdwatch on any hour that weekend, could and maywell produce results that as i see it are worthless.. ExAMPLE: If me and 9 other people in my area spot 10 sparrows each that will give you 100 sparrows if we all did the watch at same time, if at different times the reading could be 10 up to 100.

Could someone with better brains than me put me straight on this,

Regards Alan
