This is Bud writing once again, this time on Monday morning, from the deserts of Chile. I apologize for the delay in these reports. We have been strung out all along the north central coast. In the last two days the three teams have been widely separated each night and the satellite base station wound up 300 miles away from the laptops. However last night we were all able to rendezvous in Caldera at the southern tip of the Atacama Desert, the driest place on earth. The days are cloudy until the afternoon when the sun gets pretty intense.
As in all field studies, the reality often diverges from our expectations. Just before we departed for Chile, we heard from Christian that his population of peregrines in the south were absent this year. He had seen only a single falcon where there were normally 14 or so during an 8 day pre-survey. This was daunting news as we had planned to trap to the south.
We made a change in plans to start on the central coast and work our way north to the Atacama where we knew there were falcons. We started south of Valparaiso and worked north in separate cars. However, as these things go, we did not know that this was the last two weeks of summer vacation in Chile. There were thousands of people everywhere. Each trappable beach was covered with families, dogs, the works, which made it difficult to trap there. So the last few days have been a survey up the coast looking for birds. Those that we have seen have been mainly in cities. They love the new cell towers present in each town and we have learned to look for them there first. Unfortunately these structures are usually located right in the middle of town among the buildings, stores and streets, again making it almost impossible to trap there.
Christian knew of a pair using an old cathedral (built in the 1500s), in La Serena, a gorgeous coastal town. We went there and found an adult male and female perched together on the bell tower. So we asked around and we have received permission from the Archbishop to try to trap there on our return. We are racking our brains trying to figure out a way to capture them. We’ll see how it goes.
We are also working on an adult female at Tongoy who always uses a cell tower, ignores our bait, sleeps all day and hunts the local bats at night. Zach and I are scheming out a new technique. More later.
In short, we are finding that the birds are scarce and not easy to trap.
In the meantime, Tom and Mark in one car and Zach, Kathy and I in the other have been driving the desert highways and side roads (many 4WD), looking hard for birds and trying to shorten the learning curve. We are all feeling the pressure to catch a bird so we do not disappoint all of you.
Yesterday, we had a break-through. While driving the main highway north, we found an immature female in Copiapo. Zach threw for her and she came in immediately and was caught. We were ecstatic. She was a very small immature female tundra falcon (714 grams) and we thought we had our first candidate for a radio. However, Zach had noticed that she had a wing injury that appeared to be a week or two old. This, coupled with her small size, argued against a tag. We all felt that she was having a hard enough time, so we released her back into the wild without a transmitter.Last night we all camped on a beach south of La Caldera and got together for the first time in days. We generally get to bed around 2300.
We brought her back to camp and Tom put on our first satellite transmitter of the trip. So based on the last two birds, we are hoping that we are in the right habitat now. The Atacama is dry, sandy, and has little vegetation to interfere with finding and trapping the birds.
We know from work Christian and I have done on the past that there are many peregrines in this area. We caught 9 here many years ago. So our plans for southern Chile have transformed to Atacama tundra peregrines for now.More later,
Bud
