What happened to my spinach seedlings?

My recent sowing of spinach completely vanished. No wilted seedlings, no clipped off plants, just gone! Seedlings of radish, turnips, kohlrabi, beets, carrots, parsley, and cilantro are completely untouched. I suspect a bird of some sort, but I really am baffled. Anyone out there with a similar experience or a possible explanation?

Oooh that sounds weird cactusman :(
Sorry I have no explanation to offer. Can't think of anything that would choose spinach over the other goodies on offer. Perhaps slugs/snails? though they should leave some telltale behind I should think

Cactusman==look at my post for what eats broccoli. Wierd things are happening this year down in Texas.
