Depends.
Here, the clover doesn't get as much action first thing in the spring--thinking like you because it is just a big buffet out there and a number of wild plants are preferred. The fawning does are more reclusive, too.
Clover gets more more play we get into summer but they will walk across clover to get to buckwheat, if I plant it. After the first frost or so, they turn their attention to carbs and winter rye or winter wheat become the draw.
