Bulletin 179 - Birds of the Big Island Hawaii

Lisa and I had a return trip to the Big Island in June. As luck would have it, we missed several birds on our trip in December and had to return to try and find them. Darn..LOL.

The native Hawaiian forest birds have been decimated, as I recounted in December in previous bulletins.

There were 3 of these birds on the Big Island that we missed on our previous trip, so we hired a guide, Jack Jeffrey, to take us to the Hakalau Forest NWR. Jack was, for many years, the resident biologist for the US Fish and Wildlife Service at Hakalau. This refuge is only open at certain times to the public, but guides have access virtually any time. As you can see on their web site, Jack took all the photos and is an excellent photographer. You can reach Jack by email jjphoto@hawaii.rr.com

All 3 of our target species were in the refuge. It is very definitely a rain forest as it rained almost all day of our visit. We were soaked before we even got there! Below 4000' elevation, Hakalau receives 250" rain annually, but above it is only 150". There are endangered plants as well, including some lobelias that Jack showed us that have less than 5 plants existing in the world.

The first bird is the Hawaii Creeper (Oreomystis mana). This small (5") endangered bird is olive to gray above and lighter below. It has a dark mask and straight bill. It is an insectivore, and creeps nuthatch-like up and down tree trunks and branches. Here is one that caught a large caterpillar. It is endemic to the Big Island.

The Akepa (Loxops coccineus) is small (4.5") honeycreeper that is unique in that it nests in holes in trees. This bird is found on both Maui and the Big Island. The Big Island males are bright orange with dark wings. We finally saw one in the mist, just before leaving for the day. Jack said that there only 2 other totally orange birds in the world.

We did not find the 3rd bird. We also saw some other forest birds and of course took their photos. The Iiwi (Vestiaria coccinea) is the classic Hawaiian honeycreeper seen in all the travel brochures with its long curved red bill. The adults are red with black wings and tail. They can usually be found at the blooming Ohia trees. This one was completely upside down, while feeding on the nectar. The juveniles are green. We saw one this time, but were unable to get a photo.

Interestingly, the Ohia trees also come with yellow blossoms. I don't recall seeing one before, so they must be much rarer than the red.

Another red bird with black wings is the Apapane (Himatione sanguinea). It is IDed by the short black beak, black legs, and white belly and undertail coverts.

The juvenile is brownish.

The male Hawaii Amakihi (Hemignathus virens) is bright yellow-green with a black mask. This one was preening and just once stuck his head out from under his wing.

Females and juveniles are more olive coloration. The juveniles may lack the black mask entirely. I think this bird may be a juvenile.

There are many introduced birds in Hawaii as well. We found 3 that we did not see on our first trip. The only songbird was the Eurasian Skylark (Alauda arvensis). This 7" streaked brown bird is seen frequently on fence posts in open country. It is also on the ABA check list as it was introduced in Vancouver BC, but may already have died out.

The Chukar (Alectoris chukar) is an introduced gamebird in the partridge family. The large (13") bird is easily IDed by the gray overall color, black markings, and red bill and legs. The sexes are similar. It is also on the ABA check list as it has been introduced widely in American west as a game bird.

The Hilton where we stayed has a lagoon that is used by Green Sea Turtles (Chelonia mydas) to feed and rest. It was exciting to see these gentle reptiles up close. The Hawaiian name is Honu.

Happy birding and photography,
