Ornithologist question?

Question

When you become an ornithologist do you work on all birds or a group like penguin, hawk etc

Answer 1

I work mostly with passerines, and specifically work with a couple endangered species (that are passerines)  I occasionally get to band baby hawks in the nest and have recently worked with  endangered Terns (they nest on the beach).  I basically know how to identify ANY type of bird I see, and know the call or song for most birds as well,  but don't study all of them for my job.  

Answer 2

I'm not an expert, but depending on what you intend on doing for a job, you can learn more about specific species of birds or types. like, you can be an ornithologist, know the basics of most birds but know a lot about raptors (carnivorous birds) or more specifically Hawks, or even more specifically coopers hawks...note, you should probably look up if this info is completely accurate because I am not completely sure...
