Indian Golden Oriole
Scientific name : Oriolus kundoo
Males are bright yellow, black wings and inner tail feathers. They have a yellow patch on the wings, the yellow outer tail feathers, a black stripe arise through the eye that gives it a masked appearance, and the fleshy pink bill. The female is dull greenish-yellow overall with dirty brown/green wings and a completely yellowish tail. Both males and females have a red iris. Most often found feeding in tree canopies either singly or in pairs. They generally give a harsh “krrrrrrrrrrrr” call while feeding. In-flight, note its characteristic dipping flight style.
