Message: <blockquote data-quote="captaincarot" data-source="post: 1717921" data-attributes="member: 80825">the rules are clear though.your count is the largest number of any single species that can be observed simultaneously in your garden within that hour.menaing you must be able to see them all at the same time.this then removes identifiable birds from skewing the data, it also removes sexual dimorphism from skewing the data.so for example if you have 4 male and 0 female observable at one time then 4 female and 0 male observable at another time.  add to this the one with the funny leg and the other with the white patch on one wing and suddenly you are recording 10 birds, but following the rules your count is 4 as that is the maximum number of blackbirds observed at any one time.</blockquote>
