the Crop remains full with feed due to digestion not possible when the temperature drops down below 18°C & birds busy in huddling at night in the winter season
Accumulation of blood on heart auricle. In severe hypothermic conditions, the body needs excess heat for maintaining balancing inside & outside temperature Thu why heart became highly pressurized to increase blood flow but unable & ruptured blood vessels in winter.
destruction of hepatocytes by abrupt blood followed by ischemic necrosis that why liver became, harden, increase in size, wide area of necrosis & discolor death after huddling
Ruptured of the right aorta when birds forcefully pumped the heart to increase blood supply to extremities fo the production of heat in cold stress.
severe congestion of lungs when excessive respiration to increase metabolism by which produced heat in hypothermic condition
