Don't stop! They know when to carry on about migrating. Stop when you have no birds.
Whenever there are no more hummingbirds to feed. Hummingbirds migrate by internal calendars based on day length, no food availability, so leaving your feeder out will not stop them from migrating, A good rule of thumb is to leave your feeder up until two weeks after the first hard frost to provide extra energy for late-migrating hummingbirds.
The native birds in Tennessee are songbirds, seabirds, and hummingbirds.
When you feel like it!
You stop feeding them when they die.
Most birds do not. However, hummingbirds may spread pollen when feeding on nectar from flowers.
Yes. They are called Sun birds there. No, there are no true Hummingbirds. The nectar feeding ecological niche is filled by a group of birds known as Sunbirds, which are larger than hummingbirds, but they share the ability to hover while sipping nectar from a flower (and pollinating it at the same time)
It's helpful not only to the flower, but to the environment. When hummingbirds visit flowers, they are not only feeding on the nectar, they pollinate the flowers which in turn allows plant to produce fruits or seeds.
Never, they need twice their body weight in nectar to survive. If not, they will die. ------------------------------------------------- If you live in an area where hummingbirds migrate south for the winter you should keep the feeders out until nectar is no longer being taken and make sure that the feeders are out early in the spring to catch the first arrivals for the next summer.... basically the first answer is correct if you live in a country where humming birds are present all year.
When you stop feeding it
Tennessee abortion.
you don't have to stop hand feeding your lorikeet if you do though it just might make the lorikeet trust you more.
