Yep. This morning for instance hunting Branta canadensis*. We were set up with probably 80 to 100 decoys and first thing we had birds working us and we were calling like we thought we should. Nothing. They'd look at us and circle but wouldn't commit. Finally, we just said, "F@^* it", and didn't call when they'd come our way. We ended up killing 26 geese in about an hour. They didn't want to hear a bunch of calling. We didn't call and they came in like they were on a string.
