Target Birds: Oahu Elepaio, introduced forest birds
Kuliouou Valley Trail runs along a creek into Kuliouou Forest Reserve. The trail is fairly easy going for the first mile and then becomes slightly more difficult due to slippery rocks, roots, and short steep sections of trail. The area is great for numerous introduced forest species and also is very reliable for Oahu Elepaio
From route 72, Kalanianaole Hwy, turn north onto Kuliouou Road. After .35 miles you must turn left to stay on Kuliouou and then turn right again at the next road to continue once again on Kuliouou Road. After .6 miles take a right onto Kalaau Pl. Park along the street near the cul-de-sac and walk to the asphalt road at the end of the cul-de-sac. Take a left at the first fork on the asphalt road and then after ? take the right fork onto the dirt trail. After a few hundred meters, there will be a sign for the Kuliouou Valley Trail and the Kuliouou Ridge Trail. Take the left fork to continue on the valley trail. It is roughly 1 mile until the trail hits the stream (N 21 14’ 45” W 157 43’ 32”), but then doesn’t cross and still parallels the stream on the east side. From this area on is where I’ve had the most success with finding Oahu Elepaio.
Kuliouou Trail is great for forest birds including Red-whiskered Bulbul, Red-billed Leiothrix, and White-rumped Shama. Although Oahu Elepaio can be fairly vocal and obvious during the spring and summer, during the winter the birds can be difficult to find.
