The European Starling is thought to adorn its nest with flowers to ward off pests.

One of my favorite shows is Living on Earth, an environmental program recorded in Greater Boston and produced by Public Radio International (PRI). One of the show’s regular features is called BirdNote, and you can learn a lot about individual species just from that.

The Living on Earth website recently posted this:

“STEVE CURWOOD: European Starlings can often be found scrounging through the grass of a backyard or a nearby park for tasty treats. But now and then, they’ll also pluck a marigold or other bright flower to bring back to the nest. These flowers aren’t just for decoration, as Michael Stein explains in this week’s BirdNote. It appears to bring health benefits to their young.

“It’s Living on Earth. I’m Steve Curwood.

“European Starlings famously travel in massive flocks, up to one hundred thousand birds strong at times. They can almost resemble a school of fish moving together in a squeaky symphony. And, BirdNote’s Michael Stein reports that when starlings are paired up and raising chicks they have an unusual way to keep their nest clean and healthy. …

“MICHAEL STEIN: Watch long enough, though, and you may see a starling pause in the hunt to neatly pluck a marigold or other bright flower – and then fly up to deposit the bloom in the nest.

“How romantic. But there’s more to it. Ornithologists have found that starlings regularly adorn their twig nests with fresh vegetation – the more fragrant the better. Marigolds, of course, but also elderberry flowers, yarrow leaves, and even willow bark.

“All of which – as your nose will tell you – are full of aromatic chemicals. The starlings are actually fumigating their nests. Why? The chemicals have been thought to help discourage pests and parasites. Scientists have discovered that the smelly plants may offer an even more direct benefit to nestlings – by stimulating their immune systems.
It turns out that starlings hatched in well-fumigated nests tend to weigh more and live longer than those raised without benefit of fragrant herbs.” More.

For another Living on Earth BirdNote, click here. This one is about a Laysan Albatross called Wisdom who was still producing chicks in 2018, despite the fact her 67 years made her quite old for her species. Who knew the Albatross could live so long?

This might be a good time to remind you how Coleridge used an Albatross in the Rime of the Ancient Mariner to send a message — not just to the stunned and speechless wedding guest but to us all:

Farewell, farewell! but this I tell
To thee, thou Wedding-Guest!
He prayeth well, who loveth well
Both man and bird and beast.

Wisdom the Laysan Albatross was still producing chicks at age 67. She doesn’t even look tired.

Time for another animal story. Edie Freedman has a surprising one about elephants, African farmers, and bees at a new-to-me website called O’Reilly.

“Although elephant populations have increased since the 1970s, the human population has grown even more quickly,” she writes “cutting the elephants’ habitat up into farms and roads. The elephants’ key migratory routes have been cut off in many places. As result, they regularly break through fences, where they eat and destroy crops. When the farmers confront elephants on their property, things don’t generally end well for either party.

“Lucy King, a researcher working with Save the Elephants, has spent many years investigating the problems involved in crop protection. Her goal is to find long-term solutions that reduce the frequency of human-elephant conflicts—and that can be financed and managed by local farmers.

“As Ms. King looked into the elephants’ habits for any clues to keeping them out of fields planted with crops, she noticed that they tended to avoid acacia trees with active nests of African bees. Elephants, it so happens, are afraid of the bees, and will move away from an area and warn other elephants if they hear bees buzzing nearby.

“And so the beehive fence was invented. The fences are simple, inexpensive, and easy for the farmers to build and maintain. … The hives are hung at chest height, which makes it easy for the farmer to harvest the honey, while also making them highly visible to the elephants.

“The hives, connected by wires,  are hung every 10 meters around the perimeter of a field. The farmers leave wide pathways between their crops so elephants can move past the fences along their migratory routes. If an elephant makes contact with one of the hives or the connecting wires, the beehives all along the fence will swing and release the bees.”

What a terrific solution! Where there’s a will, there’s a way.
