Green iguanas use “head bobs” and dewlaps in a variety of ways in social interactions, such as greeting another iguana or to court a possible mate. The frequency and number of head bobs have particular meanings to other iguanas. Green iguanas are hunted by predatory birds and their fear of these is exploited as a ploy to catch them in the wild. The sound of a hawk’s whistle or scream makes the iguana freeze and it becomes easier to capture. Green Iguanas are primarily herbivores, with captives feeding on leaves such as turnip greens, mustard greens, dandelion greens, flowers, fruit, and growing shoots of upwards of 100 different species of plant. Although they will consume a wide variety of foods if offered, green iguanas are naturally herbivorous and require a precise ratio of minerals (2 to 1 calcium to phosphorus) in their diet. Green Iguanas Stock Footage was filmed by Heiko Kiera aka Ojatro in Florida in 2018.
