This review concerns only the 4 hour birding tour, not any of the more general ranch or wildlife tours.
This tour more than lived up to its reputation as an incredibly good birding tour. Our guide, Peggy, is an ornithologist and runs the wildlife programs. The tour actually lasted a good 4 1/2 hours, including going over the checklist. We saw almost every south Texas rarity in the book! Peggy was very knowledgeable and really helped hone our birding skills. Our group varied from beginning to advanced birders, but we all learned a lot on this trip. The trip is all done from a small van, but we got out in several places to walk around and check out the scenery (and use the bushes!). There is a wide variety of habitats on the ranch which attracts different species. There is a feeder in one location which brings in the green jays (and the pesky javelinas). We also saw numerous alligators in a lake and stream region. There are more feeders back at the visitor's center. All in all, a terrific morning which was very easy, casual, fun, and birdy. I highly recommend the bird tour. Note - there is also a full day tour which spends the afternoon in a different area of the ranch looking for more rarities.
