This got me to thinking about the usefulness of birds economically and their role as pest controllers, especially considering that our declining species of cave bats, who suffer from white nose syndrome, receive a lot of credit for this service. I kept searching for additional proof of the effectiveness of these flying bug exterminators.

We love to watch birds, feed birds, and study birds. Many of us plan our vacations and lives around birds. We enjoy restoring habitat at our sanctuaries, where we welcome and count the birds, keep an eye on their populations, and supply nest boxes for cavity nesting birds, in collaboration with nonprofit organizations like Madison Audubon. In order to gain more insight into the life cycles and migration patterns of birds, we band them.

I was able to observe several birds actively feeding in those trees because of the early light. Initially, a pair of juvenile eastern phoebes nestled close by were removing the beetles from the foliage and nourishing them. Then came a song sparrow, and then some house sparrows that eagerly ate some as well. After that, a gray catbird flew into the action and ate a few before carrying some away. I had to find out more when a stunning Baltimore oriole soon stopped by to enjoy the feast!

“Birds can reduce the intensity of spruce budworm outbreaks and mitigate damage on spruce tree plantations comparable to effective insecticides,” says Sekercioglu, discussing the significant economic value of bird-based pest control. The value of avian control for spruce budworm in the state of Washington was estimated to be at least $1,473 per square kilometer annually. He continues by listing numerous other instances of how birds support ecosystems as seed dispersers, pollinators, and even carcass cleaners (disease control).

Analysis: The Economic Value of Birds by Cagan H. is an article on this subject that can be found in the most recent summer edition of Living Bird magazine (7/17) Sekercioglu. He mentions in his piece a book that was just released, Why Birds Matter, which was written by him, Dan Wenny of the San Francisco Bay Bird Observatory, and Chris Whelan of the University of Illinois, Chicago.
