White-browed Shortwing is a common species distributed in the mid to high elevation mountain area, especially in the Tataka region (the entrance of the Mt. Jade the highest mountain in Taiwan). Although, it is common, widely distributed, and I heard Shortwings’ sound during almost all birding I did, but I saw it with my eyeless than 10 times. Shortwing is very shy. It is used to act in the bush. If we have a top-five list about the toughest bird to see. Shortwing definitely is in. Thus, every time I see it, it makes me very excited. It has a tiny cute brown body, and with bold and unproportionate eyebrows on its head. And the loud sound incredibly comes from its tiny body. The sound is king of identified easily (White-browed Shortwing sound: https://ebird.org/species/whbsho6).
Anyway, the point is that. Recently, White-browed Shortwing is recognized as separate. It split into four species: Himalayan Shortwing, Chinese Shortwing, White-browed Shortwing, and Taiwan Shortwing. So, the Shortwing officially turns into the 29th endemic species follow the Taiwan Thrush (another tough guy...). The latest study indicated that the Shortwings differ congruently in morphology, songs and DNA (detail in https://avianres.biomedcentral.com/articles/10.1186/s40657-018-0125-6?fbclid=IwAR1dGIDQVSUR7EUAqyiEC3nVmdPhsU83k4Md9-1rg4F0POEsMbzFdD60S9g).
