Hi Sze,
There is a nest built just above a 燕窩店 in 西環, making the picture very ironic. Unfortunately the swallows haven't returned yet.
There is another nest built next to a 糖水店 just 50m from the 燕窩店 one. The first brood hatched by around Mid-April last year.
What you can see in 西環 is the swallows live by lots of 廣告燈箱 and 射燈 which were built as the 海味店 and 按摩中心 expand. The whole picture depicts a typical conflict between wildlife survivalship vs developement.
Hope this helps.
