Although I have studied wildlife my entire life, I find that my thirst for knowledge regarding these fascinating animals is far from being slaked. In fact, I honestly believe it has increased. One reason for this is that the nuggets of information I uncover constantly amaze me. For example, I recently stumbled across a fact concerning the ruby-crowned kinglet that is nothing short of unbelievable.
The ruby-crowned kinglet is a winter resident in Georgia. However, due to the habitat it occupies while it is spending the winter here, unless you went out looking for the bird, you might not realize that it is one of your backyard neighbors.
The ruby-crowned kinglet spends its time foraging for food among the limbs, branches, and foliage found from the tops of trees to thick shrubs looking for its favorite winter foods such as tiny insects and other invertebrates as well as their eggs. They also dine small berries and seeds. These tiny birds seem to be full of energy, constantly flitting about from spot to spot on their endless quest for food. As such, you would think that they are constantly burning up huge amounts of energy.
According to the Cornell Laboratory of Ornithology, such is not the case. Studies of the ruby-crowned kinglet’s metabolism have revealed these remarkable birds suggest that it may only use approximately 10 calories a day. This is unbelievable! I do not know of any other backyard bird that burns up so few calories per day.
I am now determined to learn more about this astounding claim.
