Squash trouble

[mnormand]

What the heck is nipping off my tiny yellow squash? Birds? Squirrels? Got plenty of both. I was watching one little 1" squash closely everyday, then bam it's gone. Other than that, I don't have any others. Not too familiar with squash, should there be lots of little ones now? Or is it too early? The plants are getting pretty big. Have about 5-6 plants, there are some yellow flowers but they never seem to generate a squash.

Same thing last year, didn't make any.

I tried a game camera the other day, but didn't catch any violators. Not sure what's happening here....
