The finches that Darwin studied in the Galapagos islands have evolved with different types of beaks: drilling, cracking, tearing, and fishing. This is an example of B. adaptive radiation.
These birds have adapted to their environment - they needed to drill, crack plants, fish, etc. so their beaks have changed and adapted so as to fulfill those needs.
Predation is used for hunting smaller animals, warning coloration refers to a change of color, and protective resemblance refers to an animal blending with its surroundings.
