The deceptively cute Gray Jay is one of the most intrepid birds in North America, living in northern forests year-round and rearing chicks in the dark of winter. Highly curious and always on the lookout for food, Gray Jays eat just about anything, from berries to small animals. They may even land on your hand to grab a raisin or peanut.
A thermal insulator is something that prevents heat from moving from one place to another. There are 3 main ways that heat can travel: convection, conduction, and radiation. Typically the phrase 'thermal insulator' refers to a material that blocks conduction.
Insulation may refer to: Thermal insulation, materials used to reduce the rate of heat transfer; Building insulation, thermal insulation added to buildings for comfort and energy efficiency; Insulated glazing, a thermally insulating window construction; Insulator (electricity), the use of material to resist the electric current and magnetism
