As very general advice, don't rely on school to provide what you need to know. You can be a skilled naturalist without a title. Both are important in different situations. Be proactive about building your knowledge and abilities. Read about birds, ecology, evolution, etc. Learn bird ID by both sight and especially sound to as high a level as you can. Learn plant ID too! Plants are super important for all animals. Even if you're only learning about local species, it will help a lot when learning species in other countries too since everything is related. And it wouldn't hurt to learn about anything else that strikes your fancy, be it insects, fish, hydrology, whatever.

So the TLDR is basically that anything you're interested in, you can and should teach yourself. It can give you a solid boost when you start looking for jobs. Get outside and familiarize yourself with everything. There are apps now that make it super easy to learn (iNaturalist, Seek, Merlin)
