Birds like people need water to survive. Most birds drink every day. They also like to bathe & this helps them manage parasites.
I am very pleased to see that water is being provided for birds & other wildlife in many Sydney parks. Unfortunately this is not happening (as far as I am aware) across Marrickville LGA.
Until recently birds in urban areas have had to source water from home birdbaths, from storm water drains & puddles when it rains. A lack of fresh water must have a negative impact on birdlife forcing them to travel long distances for water to drink.
I think this new trend of a tray beneath taps and drinking bubblers is a great initiative in supporting biodiversity & I hope it becomes the norm.
