Don t forget to search cold places. Once you find your iguana, if it is cold, slowly warm it up and give it food and water. If your iguana is lost outside, then you have a bigger task ahead of you. The best thing to do is get some friends to help, and to break down your search area. If you take it section by section, it will be a bit more manageable.
Iguanas blend in, like they are supposed to do.
What may seem like a bright green iguana can instantly look like bark and dull green leaves. Even on a chilly day the ig can get warm if it is sunny enough. The best times to look are mid to late morning and mid afternoon. This is because it provides the best sun along with some good cover by vegetation. It can be easier to wait until you see the iguana, rather than actively looking.
