Conservation Corner: Plants that stain the landscape, deck, and car – Lancaster Eagle Gazette

I knew it was coming. I expect it and dread it every year, but it never fails to catch me by surprise. And so, when I walked outside one morning this week to leave for work, I was greeted by the annual unwelcome sight. Streaked across the middle of my trucks hoodwas a splatter of epic proportions. Some unknown airborne visitor had made a mid-flight digested deposit that painted a picture in a bold contrast of rich purple with strokes of white. Ah yes, we have now entered the season of berry bird bombs.

Bird droppings are a year-long nuisance that I have learned to accept as a byproduct of my active feeding efforts that is the result of a self-fulfilling prophecy of sorts. Erecting a bird feeder attracts birds and consuming food creates waste, so when you entice a large group of animals and give them a buffet you kind of have to accept the obligatory ordure. However, you dont have to be a bird enthusiast to suffer the wrath of their digestive tract, as its well-known that birds have an uncanny way to detect any freshly washed window, wall or landscape feature.

The problem with certain times of year is that there are seasonal changes in birds preferred food choices that increase both the production and potency of their poop. These seasons usually coincide with the ripening of our multitudes of berries and small fruit. While fruit such as crab apples that have pale flesh may result in only an increase in volume of droppings and little other side effects, others can create the potential for permanent defacement by defecation.

The most damaging of these fruits are those that ripen into dark colors of red or purple and, unfortunately, a lot of them are found growing around our yards and gardens which make it easy work for the birds to leave their mark on our stuff. Cultivated varieties of blackberry, raspberry and grape can make minor contributions, but because most people also enjoy the taste of these, birds dont usually consume enough to cause widespread dropping distribution. As I find out each year,there are a few widespread, wild species of plants that produce hundreds to thousands of dye-packed morsels for birds to devour.

The pair I deal with on a recurring basis are mulberry trees and pokeweed plants. We have two species of mulberries that occur in Ohio: the native Red Mulberry and the aggressive, non-native white mulberry. Despite the misleading name of the introduced variety, both types of mulberry produce fruit that ranges from burgundy to black when ripe. My trees produce a bumper crop seemingly every year and birds, along with raccoons, squirrels and deer, will pick my branches clean usually before a single berry hits the ground.

Pokeweed, on the other hand, seems to be targeted solely by the birds around my yard and ignored by the furry creatures. While ripe pokeberries are toxic to humans, there are accounts of Native Americans using it to dye clothing, decorate their horses and even as a war paint although it may be possible to absorb the toxin through your skin, so I wouldnt advise trying this at home. In more recent times, there are even reports of Civil War soldiers using fermented pokeweed juice as an ink to pen letters from the battlefields.

Mulberries, too, contain a pigment that is currently used in some places around the world to create fabric dye and as a food colorant. The moral of this story is that the stuff inside these fruits has long been known as a potent colorant so its understandable why the accidental artwork left behind by birds can leave permanent stains on light colored paint, wood and metal.

I guess Ill be giving the truck and house siding a good once-over each day until the berries are all gone lest I end up with a polka-dotted mural courtesy of our feathered friends.
