If you cut out the tree area you could use the contrast between bird and sky and count the number of continuous areas. 

It's far from perfect.

Thanks for the reply. Is there any software that can do the counting? I've tried ImageJ, but the cell counter plugin seems to only recognize circular objects.

I could probably write something but in order to get a fairly accurate count I would need a video or at least a couple of pictures.

Basically you can find the differences between 2 pictures aka the moving birds. Then create a spritesheet from the data and all you would need to do is count the length of the returned array.

If you don't feel like coding it yourself you can use adobe photoshop to find differences between 2 photos and https://www.codeandweb.com/texturepacker/tutorials/how-to-create-a-sprite-sheet will generate the spritesheet and return a count of sprites.

 

 

It would be great if you could help me write some simple codes. If that's cool with you, I'll send you a video (I'll try to get some footage this weekend). If not, it's all good, since it's probably too much to ask for.

Or could you maybe tell me more detail about how to use photoshop and spritesheet to count the difference? 

Hi I guess this is a question about image analysis. I'm looking for an automated method of counting the number of bats in pictures, like the one below. I don't have a background in CS, so preferably I need something that doesn't require any programming. Please let me know if there exists anything that fits this purpose. Thanks in advance.

FYI this is for my senior project. I'm studying how Mexican free-tailed bats synchronize their emergence. For instance, how does their echolocation intensity correlate with this group behavior. (Maybe someone will be interested in this)
