Carol, I don't think all birds can do this, but yes many birds can raise their crown feathers, often during alarm or during various interactions with other birds of the same or even different species.

Are all birds able to raise a crest even though they normally do not have one? Is it something that they do when they are agitated, angry, or upset? I took a picture of an American Tree Sparrow with a "crest". I have never seen this before with a bird which doesn't have a crest. Maybe it's not called a crest on birds without them. http://www.pbase.com/carol_keeler_photo/image/131804983 This made me wonder if it is something all birds can do when so motivated.
