This Clay Lick's for the Birds!

Traveling to the Peruvian Amazon rain forest meant I saw many new things each and every day. One of those new things was a clay lick. Before this trip, I had no idea what a clay lick was or why birds would visit it. By the end of the trip, my knowledge of tropical birds had grown, and I was fortunate enough to make two trips to a clay lick. What I saw amazed me.

My group’s sojourn into the rain forest took us to the Tambopata Research Center (TRC). While providing tourists with ecological opportunities and adventures, it also functions as a working research facility where the main focus is macaws. TRC is located close to a sizeable clay lick. The most basic description of a clay lick is that it’s a cliff of clay where birds, such as macaws and parrots, come to eat. Researchers think the birds do this because the clay helps neutralize the toxins from other foods they eat, such as berries. However, the research on clay licks is still being conducted in the field.

Going to the clay lick involved an early wake-up call because we left TRC at 5:00 a.m. We needed to be in place at the clay lick observation area before the birds arrived. The clay lick was not accessible from TRC by foot, so we took boats to the viewing area. The boat ride was just a short ten minute jaunt down the river. Our journey to TRC had been a total of eight hours on the boats, so ten minutes seemed miniscule in comparison.

The first morning we went to the clay lick, it was still dark. The sun had just started to peek over the horizon, and the color of the sky against the outline of the forest was like a scene from a painting. We loaded into the boats and headed for the clay lick. I wore my knee-high rubber boots, but I took them off for the boat ride. The guides told us that if we happened to end up in the river, the boots would fill with water and drag us to the bottom. So, I always took them off when I was in the boat.

The river was shallow in places, and as we maneuvered to the clay lick, we hit a set of rapids. I thought for sure we were going to capsize as the boat rocked from one side to the other. I grabbed hold of the sides and held on for dear life. All I could think about was what I would do if I ended up in the water. I was glad I had taken off my boots! The boat driver and our guide in the front, whose job was to push us off protrusions in the river, handled the situation with ease, but I was glad when we reached shore.  It was the only time in all of our boat rides that I felt afraid.

Once we were ashore, we had to walk for five minutes to get to the viewing area for the clay lick. We each had to carry a little aluminum folding chair as well as our own backpacks. The viewing area was across from the clay lick with an inlet from the river in between. We set up the chairs, and then we waited.

There wasn't anything to do at this point except wait for the birds to arrive. We could hear birds and monkeys in the forest, and occasionally we would see birds fly in the sky. At one point the howler monkeys started to make noise, and they sounded like a freight train. The other birds and monkeys joined in until they all made the most awful din. And then...it started to rain. I was shocked by this because it seemed as if the animals knew the rain was coming, and so they called out their warnings to the surrounding area. I don't know if the animals’ calls were a coincidence or not, but it was a surreal moment for all of us. The rain didn't last long, but it was heavy enough that I was glad to have my raincoat and umbrella with me.

Finally, the birds showed up at the clay lick, and they all came at the same time. They swooped in and out to eat the clay. We saw about five different types of parrots and three different types of macaws. The guides had brought along a telescope, and through it we could see the birds well. When they were done at the clay lick, some of them perched in nearby trees, so we studied them even more. After awhile, all the birds flew away, and we wondered what had triggered their departure. The entire spectacle left me with the impression that the birds were purposed and coordinated in their visit to the clay lick. We humans were the ones who wanted to try and understand the meaning behind it.
