First real cool front of season moving in now. And, yesterday AM, noted a change in hummingbird feeder activity. In past 48 hr have only seen a 3 oz drop in nectar. Very sporadic early AM visits yest & today by 2 immature Black-chinneds only. So, looks like bulk of fall hummingbird migration may be done? Might give my feeder another week for stragglers.
