What are four ways an exothermic (cold blooded) organism's behavior helps regulate its temperature?

Answer 1

Shivering!!!

Answer 2

"Ectothermic cooling

Seeking shade is one method of cooling.

Vaporization: Getting wet in a river, lake or sea.
Convection: Climbing to lower ground from trees, into valleys, burrows, etc. Entering a cold water or air current. Building a nest that allows natural or generated air/water flow for cooling.
Conduction: Lie on cold ground.
Staying wet in a river, lake or sea.
Covering in cool mud.
Radiation: Find shade. Enter a burrow shaped for radiating heat. Expand folds of skin. Expose wing surfaces.

Ectothermic heating (or minimising heat loss)
Convection: Climb to higher ground up trees, ridges, rocks.
Entering a warm water/air current.
Building an insulated nest or burrow.
Conduction: Lie on hot rock.
Radiation: Lie in sun. Fold skin to reduce exposure. Conceal wing surfaces. Even though fish and other ectotherms have developed the ability to remain functional even when the water temperature is below freezing and some even use natural antifreeze to resist ice crystal formation in their tissues; amphibians (also ectotherms) must cope with the loss of heat through their moist skins by evaporative cooling; reptiles, like amphibians must warm their bodies by behavioral adaptations; the stratum corneum they possess limits heat loss by evaporative cooling."

Answer 3

burrowing
basking
i'll keep thinking for 2 more
