The warm winter means that a lot of flowers are ahead of their normal schedule for sprouting and (presumably) blooming. Daffodil shoots started appearing during the first week of January, and already some flower buds seem ready to open. They might not get far, though, if they keep getting chomped like this one was. I suspect this was the work of a squirrel. Daffodils have a reputation for toxicity, so they ought to be safe from this sort of damage.
