Comments on: Water/Birdbath heater this winter? http://www.backyardbirdingblog.org/?p=224 A Blog for Bird Lovers Thu, 10 May 2012 02:23:59 +0000 http://wordpress.org/?v=2.9 hourly 1 By: Mule http://www.backyardbirdingblog.org/?p=224&cpage=1#comment-310 Mule Sat, 30 Jan 2010 07:01:04 +0000 http://www.backyardbirdingblog.org/?p=224#comment-310 Elevation on any perch is prefered by most birds for security. From a scientific standpoint, a birdbath located on the ground would take less electrical work to maintain a contstant temperature. The reason is found in why liquid on bridges freeze faster than the road leading to or traveling from it - that being less surface area exposed to the chilly air. I would leave the heater running 24/7. If you let the water freeze overnight, it would take far longer (more electrical work) to unthaw. Have fun birdwatching this winter!
