Birds are often described as indicators of the health of our environment. When bird populations change, they're often telling us something about the ecosystems we all depend on. That's one reason projects like MY Garden Birdwatch matter. Returning this July after a four-year break, the nationwide survey invites Malaysians to spend just 30 minutes observing birds in their local area and contribute to a growing body of scientific knowledge. Joining us to share more is Liu Lai-Wah, an avid birdwatcher and Secretary of the Malaysian Nature Society Selangor Branch Bird Group.
