No they are not. They are considered endotherms.
birds are not ectothermic or (cold-blooded) they are endothermic or (warm-blooded)
Birds are endothermic. Reptiles are ectothermic and are referred to as "cold-blooded."
Practically all except for whales and dolphins, and marine birds if you count those as sea animals. Only mammals and birds are endothermic.
they are ectothermic
All birds are endothermic. Thus the hummingbird is endothermic, meaning it can homoeostatically maintain a constant internal temperature.
All tortoises are ectothermic, which is commonly referred to as 'cold-blooded'. Tortoises are reptiles, and all reptiles are ectothermic, as are fish and amphibians. Their body temperature is dependent on external environmental conditions.
Fishes, amphibians and reptiles are ectothermic while mammals and birds are endothermic.
A squid is ectotherm. Any animal except birds and mammals are ectotherms
Birds are endothermic. Reptiles are ectothermic and are referred to as "cold-blooded."
Robins, like all birds, are warmblooded or endothermic.
A harp seal is endothermic, able to maintain its own body temperature. It is a mammal, and mammals and birds are endothermic. The term 'endothermic' is the biological term for an animal that is warm-blooded.
Practically all except for whales and dolphins, and marine birds if you count those as sea animals. Only mammals and birds are endothermic.
they are ectothermic
Ectothermic!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
its ectothermic
Newts are Ectothermic
Birds are warm-blooded/endothermic. Reptiles are not. They are cold-blooded/ectothermic. Reptiles such as snakes and terrapins must bathe in the sun to get their body temperature to an optimal. Birds can control their body temperature internally.
Fish, amphibians, reptiles, birds and mammals. Fish are ecothermic, aquatic vertebrates. Amphibians and reptiles are ectothermic vertebrates. Birds and mammals are endothermic vertebrates.
