In some cases, behavioral Iraits are used in dichotomous keys. For example, some frog speciescan be identified by their croaks.Goal: Use a dichotomous key to identify albatross species found in California.1.Compare Take a close look at organism B.A.How does organism B differ from organism A?Large areas of the bird are coveredingrey and black fealhersB.Whal physical Iraits do you think can be used to help identify organism B?Colour of beak, fealhers. and feel2.Identify: Use lhe Gizmo Io identify organism B Then, identifylheother albatrosses included inlheCalifornia Albatrosses key.
