Economic Importance for Humans: Positive
An attractive bird, Altamira orioles are popular among bird enthusiasts, potentially acting to draw ecotourism to areas they inhabit. As any member of a community within an ecosystem, they are integral to the function of the ecosystem, contributing to its health and beauty.
Economic Importance for Humans: Negative
There are no known negative effects of Altamira orioles on humans.
Other Comments
Altamira orioles have been integral to some stimulating research concerning the evolution of plumage in the genus Icterus. Dr. Kevin Omland has found several instances of convergent evolution in a variety of plumage characters within the genus, which can be summarized into two plumage types: Altamira plumage type and Baltimore plumage type. Omland and collegues have found that, while Baltimore orioles Icterus galbula, and Altamira orioles have very different plumage, their DNA characteristics demonstrate that they are quite closely related. Furthermore, plumage characteristics that are strikingly similar to that of Altamira orioles can be found in more distantly related species, such as spot-breasted orioles, Icterus pectoralis. (Omland and Lanyon, 2000)
There is a consistent trend within the genus Icterus for males and females of tropical, non-migratory species to share plumage configurations. However, males of most temperate, migratory species have bright plumage characters and females have dull characters. In addition to his other work, Dr. Omland and his graduate students are trying to understand the function of bright female plumage in these and other tropical orioles.
