Unda49, I can't say if this company offers birding tours because my family was with Donald and my wife asked a question about a bird and he was honest by saying: "The only bird I know is chicken."
We originally booked the zip line tour and the zoo, but by the time got to Belize my family wanted to do altun Ha. I really wanted to experience the thrill of the zip line. I will have to leave that for another time.
I have to say that I will go with all the positive reviews about Donald Ramirez. This guy knows everyone and made our day in Belize a fun day. The ruins was a great tour. He knows what he is talking about. After our tour of altun ha Donald gave us 45 minutes to walk around and climb temples. Instead of climbing temples I followed different groups and their tour guides around. One thing I can say is that none of the tour guides spoke as if they knew what they were talking about. Donald is a real pro and knows who to work with strangers. At the end of the day I felt like Donald was a part of my family. i can see why visitors to Belize speak well of Donald Ramirez. I experienced it myself.
