I have a trip report and bird list of my trip in January 2004 with Bill Clark/Raptours online here:

In two weeks, the tour group had 51 diurnal raptors, of which I saw 50. Well, I did see the 51st but just a blur as it flew away so I don't want to count it on my list. 2 large owls. Over 300 bird species total. Lots of big animals as well.
