I heard humming birds eat them. You could try to set up some humming bird feeders and see if that helps.

This software probably already exits but I have been trying to make 3D panoramas. My current workflow is to take the 3D left-right images and separate them into left images and right images using a bash script. Then use Hugin to make two panoramas and combine them with gimp. It’s kind of a pain. It would be nice hugin cloud just the 3D images and do it all for me.
