Tai Po has been designated as a site of special scientific interest with important ecological value. Tai Po Egretry is the cradle of egrets for generations. However, under inquiry, it was found that most people knew very little about the wildlife here. Until 2017, tree pruning works were carried out by the LCSD at Tai Po Egretry, led to a large number of injury of egrets. The incident has brought the public attention to Tai Po Egretry. Up to now, although the problem of egret dropping excrement has not been solved yet, Tai Po residents have successfully worked out a corresponding solution to coexist with egrets. Unfortunately, Tai Po residents still do not know enough about Tai Po Egretry.Hence, the project attempts to record the daily life of egrets with interesting graphs, making people understand the egrets. Additionally, the emergence of the mobile Observation bus stop allows the public to appreciate the egrets and learn about the ecology of egrets in Tai Po from their daily life.
