Dung-on-a-twig: Mistletoe and Birds
[Part 1]
Yes, we have mistletoes here in the Philippines. Mistletoes are botanically interesting plants as they are hemiparasites (or partial parasites). They usually grow on trunks or branches of trees and send out roots that penetrate the host tree's branches. They can generate their own food through photosynthesis but they can also extract some nutrients from their host tree.
Mistletoe comes from two Anglo-Saxon words: "Mistel" meaning dung and "tan" which is a word for twig. So, mistletoe means "dung-on-a-twig." This name came about when early botanists observed mistletoe would often appear on a branch or twig where birds had left droppings.
And this is how mistletoes are spread: A bird (like this immature Buzzing Flowerpecker) eats the very sticky berry fruits of the mistletoe and then poops and wipes it off another branch. This flowerpecker, by the way is a common, widespread Philippine endemic found in most islands except Palawan.
Next week: another bird showing this interesting behavior. Happy birding!
