Hong Kong Sparrow Census 2021 – Surveyor Recruitment!



Have you ever paid attention to Eurasian tree sparrows, the little birds living around us? How well do you know about these lovely neighbours?

Researches on birds are not solely the work of ornithologists (bird experts). As “Citizen Science” becomes an international trend, it is believed that the general public can also take part in scientific research and conservation work given simple training. Hong Kong Sparrow Census, began in 2016 and held yearly, has been providing important baseline data on the distribution and nesting preference of tree sparrows in Hong Kong. This will be a solid foundation for monitoring population dynamics as well as changes in urban environment in long run.

Join us now, contribute to local bird conservation while enjoying bird-watching!
