How often should I record an observation for the same organism?

How often should I record the same organism in the same location? My bird feeder has the same cardinals that visit every day. The plants around me are still here from last week. But both of these examples will likely change over time (short and long). I feel like I should be recording these organisms regularly so one can see trends and note the absence of the organism and the reemergence (or return). I think it would be interesting if I could have an observation that has a start and end date. Thoughts?
