Mapping Singapore's Avian Life: Inside the Singapore Bird Observation Map

Overview

The Singapore Bird Observation Map is a web-based interactive tool designed to help users explore the rich avian diversity of Singapore. Built on real-time data from the eBird API, this app allows you to discover where and when specific bird species have been observed across the island. Whether you're a casual birdwatcher, a researcher, or just curious about local wildlife, this map provides an engaging way to visualize bird activity in Singapore.
