Last Saturday I fed many of my bees. I only use top feeders. I happened by one yesterday afternoon (high of 39) and looked in to see if they had consumed the sugar syrup.
To my surprise they were working it as I popped the top. The cluster was most likely near the top and they must have had sufficient warmth to venture the addition 4 plus inches to reach the food.
