Hi Tom! I am Anne Brooks of the Baltimore Bird Club. I am currently developing a database for the BBC that will correspond to the yellow book. I am using Excel to do this. If you wish I could email you a copy of the database for logging birds. You would have to have Excel 95 or higher to use the database, however. If interested let me know. I should have it polished off in a couple weeks. This Database is mainly for folks who are adding to their County lists for MOS, etc. It is not that useful for keeping a lifelist. I am, however, thinking of keeping my yardlist on this database for my own information. Of course this doesn't mean you shouldn't have a birding software as well. I have two and use them to sharpen skills and to leep my personal lifelist and annual yard lists on at present.. I have Peterson's and the National Audubon Society American Bird Programs. I like certain aspects of both. Haven't checked out any others. Let me know how you like what you select as I will be buying a new program before too long. Peace! Anne
