Back when I had a Zero w, I looked at a wildlife monitoring project and decided the maximum practical resolution would not work. Now I have a Pi Zero 2. What is the maximum resolution and frame rate it can record or stream?
For small birds flitting around, 30 fps does not capture their movement clearly. 60 fps would be better. The software would do something like detect movement then switch on recording and keep going for 10 seconds after the last movement. A bird might check every flower on a bush for a minute or more then another bird from the flock might arrive so the recording is continuous writing beyond any cache capacity.
I would use a top of the line microSD card to ensure continuous writes at the maximum speed of the Pi microSD card slot. The recorded file could be transferred to a server after the write so the transfer does not interfere with writing speed.
I have not yet looked at the latest camera options. I would need medium telephoto and full telephoto options to allow for placing the camera in a safe place, out of the rain and not available as a perch for the birds. I would put it out in different places when not raining heavily and retrieve it occasionally to charge the battery. I am looking at a battery that would last for days so retrieving the video by WiFi would be ideal.
The software would not have to identify the species or do anything other than detect movement. With microSD cards up to 1 TB, it could just run full time recording all day.
