Where do hummingbirds rest or hide at night if it gets too cold, is there any way we can provide desirable shelter near the feeder?
They might hide in an unoccupied tree hole but for the most part there is nothing they can do. Sometimes its a male that comes up too early, they eat like pigs and the when it gets cold again you don’t see them. They just die. Generally they are smart enough to follow the crowd and not rush to get north.
