For birds who migrate thousands of miles, flapping their wings for long distances would require huge amounts of energy they don’t have.
Why do glider pilots look for dark surfaces below them?
Darker ground or surface features heat quicker than grass covered fields. Huge black asphalt parking lots can produce strong thermals. A large tilled black soil field can be a good source of lift if the pilot can find the sometimes very narrow plume of rising air.
Are there thermals over the ocean? Sea temperatures
Slowly, patches of air begin to warm, becoming thermals. The air only needs to be a few degrees warmer than the surrounding air for it to become buoyant and start to rise. Behold, the sea thermal.

During the first couple hours of daylight, air cooled overnight may still be sinking and flowing downhill. If your morning stand is uphill from a food source or trail, you may be upwind of the deer you’re hunting until thermals take effect. The same thing applies in the evening.
Should thermals be tight or loose?
For maximum insulation, thermals should fit close to the body and have no gaps around the waist, neck, or wrists. Overly tight thermals produce discomfort, but if thermals are too loose, you risk allowing cold air in through your layers. Loose thermals are appropriate for warmer conditions.

How do birds fly on thermals?
Thermals are updrafts of warm air that rise from the ground into the sky. By flying a spiraling circular path within these columns of rising air, birds are able to “ride” the air currents and climb to higher altitudes while expending very little energy in the process.
Do thermals spiral? (See our lesson about flight.) And in order to move forward AND stay over a thermal or updraft, they move in a circle. The rising air carries them upwards at the same time. This makes their overall movement a spiral.
