May Nature Happenings

 

Over 100 North American bird species supplement their natural diets with bird seed, suet, fruit and nectar obtained from feeders.

Access to abundant and healthy food supplies is important to birds…regardless of the season. Bird feeders provide a portion of these important nutritional needs for your backyard birds throughout the year.

Birds with access to backyard feeders benefit greatly from their ability to spend less time foraging for food and more time engaging in activities that enhance their health and safety. These activities can include:

•   Less time spent searching for food and more time selecting better nesting sites and constructing higher quality nests.

•   Adults have more time available for protecting their nest, eggs and young from predators.

•   Research studies have shown that birds with access to bird feeders often lay eggs earlier than those without feeders, which is significant because earlier broods typically have better rates of survival and fledging success than later broods.

•   When abundant food is accessible to parent birds, the young birds get extra nutrition, and this can increase the nestling’s rate of growth and reduce aggression among siblings.

•   Breeding females spend less time foraging so she can better protect her eggs from predators, the young fledge earlier, and more survive.

•   Less time spent foraging means more time spent being vigilant in spotting a predator in time to successfully evade it.

•   Feeding birds in the summer will not make them too lazy, too dependent or keep them from migrating at the appropriate time! These old myths have been dispelled by modern research and observation.

•   Contrary to popular belief, recent research shows summer to be the most abundant season for birds to visit feeders.

•   The food and housing we provide can make a significant difference on how well birds will thrive and survive in our own backyards:
