Black-crowned Night-Heron - The Fairmont Orchid Hotel on the Kona Coast of the Big Island (Hawaii) had a spotlight shining on a reef in the evenings near where we had dinner. We observed three of these herons as they came to search the water for food. We didn't see them catch anything but they returned the next night.
Brewer's Blackbird - We first saw these in Palm Desert, CA, but we had never seen one perched like this in a tree.

Rock Dove - Common on all of the main islands it was first introduced in Hawaii in 1796.
Cattle Egrets - These are widespread throughout the islands where they frequent fields, roadsides, pastures, watercress ponds and taro patches. Often traveling in large flocks they will nest in mangroves or kiawe trees.
House Sparrow - These are quite abundant on the islands. Native to Eurasia they were brought from New Zealand and released on Oahu in 1871.
We saw two species from the road that we couldn't photograph because of no turnout space and heavy traffic. One was the Ring-necked Pheasant. The other was the Nene (Hawaiian Goose), which is Hawaii's state bird. This photo of the Nene is from a website.
