A great place to find birds common and local to Hong Kong is Kowloon Park. Kowloon Park is also a great place to sit back and relax after a busy day in Tsim Sha Tsui. I went to the park to relax, and while I was there entertained myself by observing and sketching some of the birds I saw. I saw several Spotted Doves, a few Magpies, and some Black-Collared Starlings(which I neglected to sketch on this trip).
The Spotted Dove is a bird native to South East Asia and is very common. It is a short, round dove whose most notable feature is the band of black and white spotted feathers behind its neck. Though their typical coloration is light dusty brown, pink, and blue, the Hong Kong variation is a noticeably darker, rusty color. From my observations, they tend to be mainly solitary ground feeders that forage through grass for seeds and insects.
The Common Magpie is a large, crow-like bird with striking black-and-white coloration. According to Wikipedia, the Common Magpie is among the most intelligent animals in the world. They have been found to be self-aware and are the only non-mammal to possess this level of intelligence. The magpies I observed tended to swoop together in small groups, rarely staying in one place for long.
