Moose across North America are dying from tick infestations that have exploded in range and intensity due to climate warming.
Moose infested with tens of thousands of blood-sucking ticks suffer from severe anemia, the exhausting physical toll of constant itching and scratching, and hair loss that impairs thermoregulation in cold winters. Ghost moose with severe hair loss are frequently seen in affected regions. Calves with heavy infestations die before spring, representing prolonged suffering before death.
