“Cool, Clear Sizzle – How to promote the benefit of backyard water features”
“Tom Hollyday of Happy Bird has developed a line of products that enforce separation of drinking and bathing. Hollyday has also put thought into energy efficient ways to heat and cool the water to compensate for those seasonal stressors of ice and heat. By separating the mess of bathing from the need for clean drinking water, the threat of spreading disease is removed.”
“Water is cool, and water sizzles. It is key to birding habitat success.”
