SINGAPORE – To the untrained eye, a songbird with a buttery yellow belly, not the fanciest of birds, could easily have gone unnoticed when it showed up at Dairy Farm Nature Park recently. But no rare visitor goes undocumented for Singapore’s bird photography community. So when the yellow-bellied warbler was first spotted by a novice birder on Sept 23 and posted on social media, more than 30 photographers showed up at the park the next day to verify the finding – the bird was the first of its kind to be recorded in the wild in Singapore.
