The Bahama Oriole

Picture

As a single-island endemic species, the Bahama Oriole (Icterus northropi) is only found on Andros Island.  North Andros, Mangrove Cay, and South Andros are the only habitats for this tropical bird.

Threats to the Bahama Oriole

Picture
As one of the few endemic species found in the Bahamas, the Bahama Oriole (Icterus northropi) is subjected to a changing world.  Lethal Yellowing Disease, anthropogenic encroachment, and brood parasitism are main threats to the bird. 


Lethal Yellowing Disease

Lethal yellowing disease affects the Bahama Oriole's favored nesting habitat.  With coconut palms in decline on North Andros Island, nesting success of the oriole is in decline.

Shiny Cowbird

Picture
The introduced Shiny Cowbird (Molothrus bonariensis) was first found on North Andros Island in 1994.  This introduced species favors the Bahama Oriole as a parasitic brood host.  What does this mean?  The Shiny Cowbird lays their own eggs in the oriole's nests leading to nest failures and increased nest competition.

Picture
Some birds, such as the Shiny Cowbird, do not rear their own young.  That responsibility is thus put forward onto the Bahama Oriole where the chicks are cared for and fed; this in turn reduces food intake for the Bahama Oriole chicks and reduces nesting success.


Anthropogenic threats

Destruction of coppice habitats for agricultural development is also a concern for the survival of the Bahama Oriole.  With increased development and habitat loss, there will be fewer and fewer places to forage and feed their chicks. Coppice habitat is important for the future of the oriole.

Location

Who we are

Thanks to the funding from the Undergraduate Research Opportunities Program at the University of Hawaiʻi at Mānoa and mentorship from Professor Melissa Price, Kenneth and Alexa are able to travel to the Caribbean to study the rare and critically endangered Bahama Oriole.  Operated out of the Hawaii Wildlife Ecology Lab, part of the Department of Natural Resources and Environmental Management, College of Tropical Agriculture and Human Resources.
