A few images to give an idea of where the tortoises were going. The blue outline on the map of Pinta shows the extent of all the tortoise movements on Pinta during the time that we were there. That´s only 2 months and they´ve covered a huge area so far. The green area is where we conducted vegetation and cactus sampling. The red dot is the spot where all of the tortoises were introduced - about half of the tortoises stayed near that point (mostly within the green rectangle) and about half went out to far flung places.

Here are movement patterns of a few of the tortoises that I´ve mentioned. Each dot represents an hourly location starting from the introduction point (red dot). Klever, the tortoise who we had a hard time finding and then had to cut his logger off in the end, has the yellow dots that move straight up towards the top of the island. Wilman, who spent some time in the lava field, is in purple. Milton, who I put up a picture of trying to mount another tortoise, is in green. Johannah, a female who has stayed near the introduction point like most of the other females, is in red overlapping with Milton.


  1. My guess is that Johannah is the prettiest and smartest tortoise there, right?

  2. Yes, of course, otherwise we wouldn't have given her that name!
