eBird is a good source of this data and can be broken down on a site-by-site
basis. It is useful now and will get better and better as more data is put
into it.
I must admit to having been very critical of eBird in the past and I still
have some reservations about its statistical soundness, especially the
assumption that eventually the good data will overwhelm the bad. However,
the on-line entry has solved most of the problems that made the earlier
versions so cranky and irritable and the products are looking not only
accurate, but useful, too.
Cheers,
Bob,
who has drunk the eBird kool-aid and is now entering 50 years of lists.
Eight down, 42 to go.
