You will probably be amazed at the extremes of climate in Hawaii, especially on Kilauea Volcano. This is one of the rare places in the world where you can walk a few hundred yards from an area of heavy rainfall to one of striking dryness. The change is due to prevailing trade winds which force moisture laden clouds up over the mountain masses from the northeast, then allow the clouds to dissipate on the leeward side of the mountains. By taking the Crater Rim drive at Kilauea, you will pass through lush fern jungle on one side of the crater and barren desert on the other.

Birds are very sensitive to these differences in climate. Most of the species you find at Thurston Lava Tube will never be seen at Halemaumau, less than 3 miles away. The same thing is true at Haleakala, although less dramatically so. To help you locate the most rewarding sites for bird study in the park, here are a few suggestions:

Kilauea-Mauna Loa

Thurston Lava Tube. This is the heart of Hawaii’s tree-fern jungle and an excellent habitat for several native species, such as the apapane, iiwi, and amakihi. Spend a few moments looking for these at the exhibit overlook, then take the quarter-mile loop path that leads through the lava tube. On the other side of the lava tube parking area a trail descends into Kilauea Iki, the site of the 1959 eruption. This delightful walk also passes through fern jungle. Be on the lookout for the io (Hawaiian hawk) in Kilauea Iki.

Halemaumau. A most unlikely place for birds; however, there are almost always a few white-tailed tropic-birds soaring within the pit.

Kipuka Puaulu. A popular name for this area is “Bird Park” and for good reason, for this kipuka, a hundred acre island of well developed vegetation surrounded by a recent lava flow, harbors 11 or more species. The commonest here are the white-eye, red-billed leiothrix, and house finch—all exotics. When the ohia trees are in bloom, and usually there are at least a few, large numbers of iiwis and apapanes are attracted to the kipuka. Other interesting birds often seen here are the elepaio, Japanese blue pheasant, and cardinal.

Mauna Loa Strip. More kinds of birds (18) have been recorded from the koa parkland along the Mauna Loa Strip road than from any other locality in the park, but you are not likely to see large numbers in any one place along the strip. The road ascends the lower slopes of Mauna Loa from 4,000 feet at Kipuka Puaulu to 6,663 feet. Several introduced game birds—Japanese blue pheasant, California quail, and chukar—may be flushed as you drive up the road. Skylarks and house finches are fairly common along the grassy flats, and you are almost sure to see an amakihi in the koa grove at the end of the road. If you are lucky you might be rewarded with a glimpse of a nene somewhere on these upper slopes.

Haleakala

Hosmer Grove and Paliku. These two localities are about the only densely wooded areas in Haleakala National Park and both attract a variety of birdlife. The apapane, iiwi, and amakihi as well as several exotic birds can be seen at either place. A delightful self-guiding nature trail that identifies many of the plants and trees winds through the Hosmer Grove.

Road to Haleakala Summit. As you drive up to the Observatory from Park Headquarters you will probably be surprised at the number of ring-necked pheasants and chukars that flush along the road. Golden plovers and skylarks are also plentiful, and mockingbirds may be seen occasionally.
