In Singapore, the wildlife list shows more than 390 species of birds. Of these, nearly 150 species are residents here, which means they can be found all-year round, and that there is evidence of them breeding here.
Birds play an important role in the urban landscape here, said Mr Lim Kim Chuah, chairman of the Nature Society (Singapore) Bird Group.
"They help with the reproduction of plants - as pollinators and seed dispersers - and control the population of bugs.
"Birds also provide a recreational and aesthetic value, as enjoying nature and watching wildlife is a great way to relax and de-stress, especially in a hectic environment like Singapore," he added.
"Lastly, parks, gardens and forests attract tourists and, to some extent, eco-tourists. This brings economic benefits to the country," he noted.
