My wife and I spent a week on the Big Island, staying at the Kona Sheraton. This was a 20th Anniversary trip, not a birdig trip, but I still managed a day and a half of birding and got all of the endemics on the island, and most of the interesting introduced birds. Didn't spend any time at all birding wetlands, etc but still photographed 35 species. I took a tour with Gary Dean of Hawaii Forests & Trails http://www.hawaii-forest.com/ , into a restricted area of Hakalau Forest NWR, which was fantastic. This was an all-day adventure, and I also spent a day up on the Saddle Rd on my own for Palila and Akiapala'au which was also successful.
