Hawks in Hawaii: Where to See Them and How to Identify Them

The Hawaiian Hawk, or ʻIo, is endemic to the Big Island. Your best bets are Hawaii Volcanoes National Park, the Hamakua Coast, and the slopes of Mauna Kea and Mauna Loa. Look along forest edges and open pasturelands, especially in the morning. Sightings on other islands are extremely rare, so focus your efforts on the Big Island.

Year-round presence makes the Hawaiian Hawk a reliable target, but early morning (7–10 AM) offers the most active hunting. The dry season (April to October) provides clearer skies and more predictable weather. Avoid midday heat when hawks often perch in shaded trees and become harder to spot.

The Hawaiian Hawk is Hawaii's only endemic raptor, so you're not likely to confuse it with other local birds. Look for a medium-sized hawk (about 16–18 inches) with broad, rounded wings and a short tail. Two color morphs exist: a dark phase (mostly blackish-brown) and a light phase (brown above, pale below with streaking). Compare with the Barn Owl or Black-crowned Night Heron, which could be mistaken in flight but have different silhouettes and behaviors.

Hawaiian Hawks inhabit native forests, agricultural areas, and even suburban neighborhoods. They favor mixed habitats with both trees for roosting and open areas for hunting. Look for them perched on utility poles or dead branches, scanning for prey. They are adaptable but most common in upland areas above 1,500 feet.

Non-native raptors like the Peregrine Falcon and Osprey are occasional visitors but not breeding residents. The Hawaiian Hawk is the only breeding raptor. If you see a falcon-like bird, it's likely a Peregrine Falcon on migration. For more on hawk species and identification, visit our hawk information hub.
