you may not hit lucky but our guide was very knowledgeable and made the trip excellent for the kids; make a day of it if you can to enjoy the cafe etc and revisit the best birds.
I booked this tour for Dec 11 at 8:00am. This tour should be 4 hours. However, they change it to Dec 9 afternoon which after my tour to Iguassu Fall Brazil which is next to this park. They drop me off there for one hour which we do not want to do two parks in one day. Our booking for this day afternoon should be a city tour at 2:00 pm. The bird park is great but is not worth for my money paid as this tour should be include round trip transfer from hotel and is four hours instead of dropping us off there for one hour.
The package includes transport and entrance ticket, I did this tour with waterfall, and the bird park is just outside the waterfall, which means for 30 dollar i paid is only the entrance ticket, far too expensive, not recommended at all, but the bird park itself is great.
