That bit always causes problems.
We take it to mean that the number you write down is the largest number
in sight - at any one moment.
If you count over a period of time, one bird could get reported as 27 as
it pops back & forth to visit a feeder.

That said, I'm sure a lot of counters do this.
(I also wonder how many bald-headed eagles & condors etc. get reported.)

It is noticeable that 70% of our regulars seem to go elsewhere on the
day of the count.
