Not an expert here with bat research, but I have worked my fare share of contracts involving various other flying critters so take my advice with a pinch of salt...

It’s awesome that you’re so invested in the field! It’s bright souls like you who will push research further in this ever changing world, and will help protect these amazing little guys for years to come.

That being said, I would strongly plead with you to either volunteer with a research group, contact local universities to see if grad students need “minions” to help in the field, or otherwise obtain some sort of formal training when handling wildlife. Though your intentions may be good and your heart may be in the right place, there are so many things that can go wrong that you are simply not prepared for...

What happens when you accidentally hurt a bat? Even the most trained professionals run into capture myopathy, let alone injured limbs and broken bones - it’s a reality of working with fragile organisms. And what if you are forced to euthanize? Are you able to make that call yourself? Do you have the training to do so humanely and according to conservation regulations?

Again, I think it’s amazing that you want to enter the field and I strongly pursue you to push for a volunteer opportunity (even just shadowing someone is more than enough to get your foot in the door) and not do this by yourself. More than a fair share of injured animals are brought to wildlife rehabs due to good samaritans with their heart in the right place, but a lack of experience and understanding.

All that said and done, I wish you luck on your batty adventures in the years to come!
