Bristle-Thighed Curlew

Birding Oahu and The Big Island

In the South Pacific, the islands of Hawaii emerge like green jewels from the vast ocean. For many tourists these islands offer beaches and relaxation and forested hikes. Throughout these habitats are  dozens of species of birds that have evolved on the island and live nowhere else in the world. Known as “endemic” species they contribute to the biodiversity and beauty of the place and also to the allure of the islands to birders. There are also a multitude of stunning species that have been introduced from foreign countries through Hawaii’s long history of travelers and agriculture.  Last there are the migrants – birds that live in Hawaii each winter and feed in its rich forests.

Birding Hawaii for the first time is certain to add many species to your “life list” and after a week of casual birding my wife and I were thrilled at the chance to see some of these winged wonders.

Endemics Species

Endemic species are often highly evolved to fulfill a certain niche. This means they often rely on a certain food source or nest in a certain area. They are highly specialized and are susceptible to habitat destruction, climate change,  and competition from introduced species. These birds did not evolve with mammalian predators and have felt the pressure of cats and mongoose which came with humans. According to ABCbirds.org, 95 of 142 endemic Hawaiin bird species have gone extinct since human arrival. Of the 44 remaining species, 33 are on the endangered species list and at risk for extinction. These statistics have prompted many studies and efforts at restoration. Hopefully efforts will successfully save some of these beautiful species. Certainly the liklihood of extinction means birding Hawaii now may be your best time to see some of the species before they disappear forever. We only saw several endemic species and hope to pursue these more on our next trip to Hawaii.

Introduced Species

Hawaii has a long past of habitat destruction and modification from humans. In the 1830s, the first successful sugar cane plantation was planted in Hawaii and “cane” plantations spread like wildfire from there. For nearly 180 years the cane plantations burned through acres and produced huge amounts of product. In 2016 the last cane plantation shut down.  However, that industry, development, military activity, and travelers introduced dozens of birds, plants, insects, and mammals. Many of these birds thrived in the warm and gentle climate and in time competed with the endemic species that lived there. We had an opportunity to see a wide sampling of these species on while birding the Big Island and Oahu.

Migratory Species

Of all the migratory species that we observed the Bristle-thighed Curlew was certainly the highlight! Very little is known about the habits of this bird, but they breed in northern Alaska and winter exclusively on islands in the south pacific. It was pretty remarkable to see them walking around the golf course near Kona!

Birding Hawaii made me realize again how connected birds make the world. Regardless of the distance and expanse they have to cover they are able to connect regions like the Bristle-thighed Curlew connects Hawaii and Alaska.  I cannot wait for the next time that I bird those gorgeous islands.
