Disease

Like other native forest birds, ‘Alalā can get sick from avian malaria carried by mosquitoes, as well as from toxoplasmosis carried by feral cats and rats. Pox virus, transmitted by mosquitoes or through contact, can cause debilitating lesions.

Loss of Hawaiian Forests

Forests that ‘Alalā once called home have been changed by human activities like development, agriculture and ranching. Cattle, sheep and pigs can munch and trample understory plants.

Due to the loss of trees and understory shrubs, ‘Alalā have less food to eat and limited cover to hide from predators.
