I am in the process of populating a Bubo list, as was suggested to me by
@Martin Bell
It is taking a while, but I will get there this week. As I'm doing it, I am finding one or two errors. For example, as I have opted to use the IOC list, I have found that Yellow-rumped Warbler no longer counts, especially as I have Magnolia and Audubon's listed. I also found that I have two birds at 105, and have double dipped on Northern Mockingbird.
The Bubo list should, when updated completely, eliminate these kind of errors, although some of the bird name used on the IOC list have proved a challenge to work out. For example, Crested Coot became Red-knobbed Cobbler.
In regards to my suddenly imposed internet access restriction, I have found a way around it, but only on one computer, and at at very restricted times, so I may yet be able to add a bird or two over the next couple of weeks. There is also a chance that the restrictions will be lifted in a month or so.
In the meantime, please continue to post any recommendations of sites, I will make every effort to catch up on them in a couple of weeks time.
