The tell-tale flash of pink leaping from the waters alerts Naomi Brennan to the presence of a local Chinese white dolphin.
Conservationists like Brennan regularly board boats in the Pearl River Delta to document how the mammals, known for their eye-catching pink colouring, are faring.
"Today we encountered three different groups of dolphins -- six adults and two sub-adults," she explained.
"They were engaging in a range of behaviour, from feeding to travelling and socialising."
For years keeping tabs on the dolphins has been a disheartening task.
The population has fallen by 70-80 percent in the past 15 years in what is one of the world's most industrialised estuaries.
But this year their numbers have bounced back -- and they have the pandemic to thank.
Well I am sharing this because some of you might not have seen a pink dolphin before. That's the bottomline of this post, lol.
