Bathing is an almost universal behavior among avians, yet scientists are still trying to understand the evolutionary advantage of clean feathers. While birds enjoy a good washing, they don’t splish and splash in just any mud puddle. They’re attracted to gently moving water that’s relatively clean. That’s where solar birdbaths enter the picture.
Solar power saves energy, eliminates cords, and, importantly, creates a quieter water pump: Birds can get skittish around new or loud noises. Some solar birdbaths also feature a battery that stores energy to power the water fountain after the sun goes down or on cloudy days. Birdbaths are a stand-alone way to attract birds to your yard, but they also make a great companion for a bird feeder. Once feathered friends call your yard home, they help boost the health (and attractiveness) of your yard by eating harmful bugs and weed seeds and pollinating plants.
What attracts birds to birdbaths?
Feathers serve several important purposes. They give birds insulation, waterproofing, and act as decoration to attract a mate. Consequently, maintaining the health of those feathers is important to keep birds alive and thriving. Almost all bird species regularly take a dip, but little research has been done on why birds bathe. There are several working theories behind the behavior, starting with the same reason people bathe: cleanliness.
Birds replace their feathers once or twice a year. However, the fronds collect dirt and bacteria and break down over time. Bathing removes soil and oils that may get in the way of flight, waterproofing, and insulation. Water can also help remove mites and bacteria that degrade the feathers.
A 2012 study of European starlings suggested that birds with clean feathers were more efficient fliers. What’s more, the scientists found that starlings that didn’t regularly bathe were less able to perceive threats and could be prone to long-term stress.
Scientists haven’t pinpointed all of the benefits of clean feathers, but they may also offer a survival advantage. In one 2009 study, bathed birds were more likely to eat food despite the threat of a predator, suggesting that they knew their agility could help them escape danger.
However, birds have their standards and don’t usually bathe in a muddy puddle. They prefer slow, moving water that’s generally cleaner. Birds also prefer shallow water; in depths of up to two inches, they can maneuver and wash in relative safety.
Do birds care about solar energy?
Birdbaths equipped with solar-powered water pumps have qualities birds like, even though the avians’ preference may not be a conscious one. Solar pumps may be surrounded by solar panels or connected to them via a cord. In the case of designs surrounded by solar panels, the entire unit fits inside the birdbath’s basin. Those that connect via a cord have the water pump in the basin and the solar panels outside of the basin.
The panels absorb energy from the sun and turn it into power that fuels the pump. Some models, hybrids, can also run off of solar or a standard power outlet. Hybrid models work well in areas where cloud cover may frequently block enough solar energy from reaching the panels.
