FIGURE 17. Nesting periods of various iguana populations. Monthly mean precipitation is indicated in mm. Precipitation varies according to altitude and aspect, but the important point is that after a 3 months incubation period, the eclosions occur at the beginning or during the rainy season. The brackets indicate the main laying period for the different species at different insular and continental locations. Note that the nesting period of Iguana iguana sanctaluciae overlaps the laying periods of both Iguana delicatissima and Iguana iguana iguana, which suggests that mating periods could also overlap, potentially enabling all three species to interbreed.
