The ''platform'' nest is a large structure, often many times the size of the (typically large) bird which has built it. Depending on the species, these nests can be on the ground or elevated.<ref>{{Citation |title=Zoology: An Inside View of Animals |first=Kenneth |last=Hyde |year=2004 |publisher=Kendall Hunt |location=Dubuque, IA |isbn=978-0-7575-0997-1 |page=474}}</ref>
In the case of raptor nests, or ''eyries'' (also spelled ''aerie''), these are often used for many years, with new material added each breeding season. In some cases, the nests grow large enough to cause structural damage to the tree itself, particularly during bad storms where the weight of the nest can cause additional stress on wind-tossed branches.
