From massive, five-foot nests of branches and twigs, to tiny nests made of foraged fiber, bird nests are amazing architectural feats! Their nests take a number of forms, from plain and simple to ornate and complex. National Aviary Ornithologist Bob Mulvihill will introduce you to the fascinating techniques and materials birds use to create safe places for their eggs and young, then lead you on a short walk through the National Aviary to search for nests.
