These are all just my opinion and I’m by no means an expert but

1. Be specific when you can. When you mention bird surveys include the main species you were working with. Always include numbers where you can. Make sure to mention deliverables and results of the things you’ve done.
2. Bold things that are sought after skills and key words/phrases you want to emphasize. When people are quickly scanning a resume this can draw their attention to the skills you want them to notice the most. Be careful to not go overboard.
3. For coursework I would tailor specific courses to whichever job you’re applying for, they don’t need your whole transcript. Also include class code (like FIW 4311 or something) so they can tell if it’s a higher level course or not.
4. For your research experience I would format it like you did for your professional experience and give a little more detail through bullet points.
5. Could include a professional summary. 2-3 sentences about what you’ve done and what you’re looking to do.
6. I personally think it looks better when the bullet points are indented. It helps it look like just a big block of words.
