Convection current move fluids upwards and downwards (like boiling soup) and distribute heat energy. An upward convection current in the atmosphere is called a "Thermal" (which usually have a small cumulus cloud on top) and some species of birds use these to gain height, circling round in them and getting taken up with the rising hot air without having to flap. When they have gained altitude they can then come out of the thermal and glide to the next while hunting or migrating.
Using the rising air in the thermals means that they save energy themselves (by not having to flap) and this help them survive.
What else can I help you with?
Is the wind a friend of the birds?
Yes, it can be. Some birds use the wind to glide and catch a "free" ride. Watch an eagle sometime and you will see it done. If the wind is too strong it can also work against trying to fly. Birds often try to fly against a strong wind and get stuck flying in one spot. I have seen this happen.
What are needed to spread out the wings when the birds fly?
Birds use their wing muscles to spread out their wings when they are ready to fly. Birds use thermal air currents, updrafts, and wind to soar and flap their wings when needed.
What does the carrying of seeds to a new place?
Sometimes it's birds and sometimes wind
What seed dispersal does nutmeg use?
Dispersed by birds- far too heavy to be dispersed by wind.
Are wind turbines used to generate electricity from the wind?
Yes. They are hazardous to birds, but the wind propels them.
How many birds are killed by wind turbines in a year in the UK?
I'm not sure about the UK, but in 2007 there were about 100,000 birds killed by wind turbines
Why does the solar wind interfere with the navigation of birds?
Birds navigate using lines of magnetism around the earth. Solar winds can disrupt these lines causing birds to read them incorrectly. therefore the bird may not be able to find where its going.
Do birds die in wind turbines?
yes they do.(;
Do birds check time using the wind?
No, they do not.
What are the different of pollinators?

Are birds afraid of wind chimes?
Yes, initially the birds are usually afraid of the wind chimes. However, wit the time after they get used, they are never afraid of the same.
Are birds afraid of windchimmes?
Some birds can be scared by wind chimes. The noise and motion can startle them.
