Bird's crest feathers and Dinosaurs
The feathers came before the wings, in limited parts of the dinosaur's body like crests, so they did not originate as flight structures. They served as color displays, perhaps for mating or other communication purposes.
Paleontologists studied these dinosaur structures through fossils and could make a relation between dinosaurs and birds, proving that birds did evolve from some dinosaur species, particularly from theropod dinosaurs.

Even if nor all birds have them, there is a huge variety of designs and heights being sometimes very discreet. Some reach considerable sizes and volume and may persist all year-long or show up during the breeding season.
One of the crest uses is exhibition during the mating period, but a few are also exposed in danger situations or attacks to scare the enemy away or to exchange signs with their group.
Because they are awesome and are worth to watch here is a gallery of crest feathers stunning displays.

The crested guineafowl (Guttera pucherani) is a member of the Numididae, the guineafowl bird family. It is found in open forest, woodland and forest-savanna mosaics in sub-Saharan Africa. It has a distinctive black crest on the top of its head, the form of which varies from small curly feathers to down depending upon subspecies, and which easily separates it from all other species of guineafowl, except the plumed guineafowl.
The great crested grebe (Podiceps cristatus) is a member of the grebe family of water birds noted for its elaborate mating display. It is an excellent swimmer and diver, and pursues its fish prey underwater.
