Good-looking specimen and light. I wish the head were parallel to the sensor and might selectively sharpen the head more. The bright yellow leaf next to the back is a bit distracting, maybe you could try to tone it down a bit. Thanks for sharing!
This is not a Red-whiskered Bulbul, it is a Red-vented Bulbul. The Red-whiskered species is a bit smaller, has a bright red cheek patch and a longer, more pointed crest. I have photographed both species numerous times in Hawaii. If you look at the "Hawaii" album in the Gallery on my website, you will see both species and see that they are quite distinct.:)
