Hello friends. I'm hoping an expert here might be able to help me. I'm new to thermal cameras. I live in a two storey house, and I suspect that there may be myna birds nesting on my roof. I can hear them walking on my roof.

I'm wondering, suppose I sit in an upstairs room, nearest to where I think the birds are, whether I'd be able to see a bird, if I bought a thermal camera and pointed to my roof. What type of thermal camera would I look for?
