When the Cure Is Worse Than the Disease

I am lucky that not far from my home there are a number of parks of varying size. One of them is a linear park that was once a short-line railroad that failed. At one point there were plans to extend a major road through these woods but that failed, too. The resulting park is called Patriots Path because it was first formed in Morris County (the path has since been greatly expanded into several counties), once known as the "Birthplace of the Revolution" because of its proximity to Jockey Hollow, where Washington's troops encamped for two winters years before the better-known encampment at Valley Forge in Pennsylvania.

The path is under the jurisdiction of the county, so it is county workers who do the maintenance. Thus, I am going to blame the county for the seemingly haphazard destruction of trees along parts of this path because of a small menace called the emerald ash borer.

The borer is an insect that, like the Asian long-horned beetle, is invasive and likely came over in wood pallets or other wood products shipped here from abroad. The borer's destruction of ash trees has been well known for months but it was only in the last few weeks signs have gone up along the trail warning of work to be done in the coming days to keep any damage from spreading through the entire forest.

When that work was finally done and the men, saws and heavy machinery I'd seen were gone, I brought MH to one part of the path for a short walk along the flat, paved trail. What I saw was horrific.

Trees were cut down and the stumps left in the ground. The cut trees were tossed aside or dragged away from the path and left in piles. Why would the county cut down trees it feared would be invested with borers and then leave them there? Did someone think the winter cold would finish off the insects? Maybe it will, but the ugliness of leaving them on the ground to become months of eating pleasure for a plethora of bacteria and insects makes me very angry.

I can understand taking down trees to save a forest. What I can't understand is leaving the area ugly so it is devalued and thus more easily ignored by people who don't care or want to understand why forests are as important to have as ballfields, dog parks or a shopping mall.

A year before, when the wind chill was in the single digits, MH and I had walked this same part of the path and we marveled at how the overflow from earlier rains and the nearby Whippany River had created huge frozen ponds. This year has been particularly rainy so the ponds that formed were deep but definitely not frozen.

Either way, it seems no one cares about these woods, all they care about is killing trees that maybe - maybe - were invested with borers. These county people are no better than my neighbors who take down a 50-year-old, inconvenient tree because they fear it maybe - maybe - will fall on their house.

There is such a thing as forest management. I've seen it at work. You take down trees to open up the understory to other types of trees. Thoreau wrote about it when he noticed that in a forest of white pines, any open ground was soon filled with oak seedlings.

Patriots Path, like many other parks, is a bit of woods in a suburban environment. When not chopped down for a housing development it is affected by the pollution from cars, lawn chemicals and even fireplace wood smoke. Too many times I have seen woods along state roads covered with choking vines, usually poison ivy but also mile-a-minute and Virginia creeper. At some point the vines will shut out all light to the trees and they will die. The state sends out mowers to cut the roadside grass but no one notices, much less cares for, the trees. The system seems to be based on benign neglect.

To those areas that proclaim, "See? We have woods here that are protected!" I say, well, I guess that's better than wiping them out and putting in a road or ballfields. But if you don't take care of the land and remove the sick or fallen trees or the vines and other invasives, people are going to ignore the woods as just so much wallpaper. Too many times I have seen people using these natural resources as backdrops to walk the dog, make a phone call or talk to their friends. Maybe it relaxes them but to me they are not walking in the woods to get away from the pressures of modern life or even to look for birds and wildlife. It's just a prettier background than walking Fido on your neighbor's lawn.

Winter is an ugly enough season in New Jersey when the leaves are down and everything is gray. Today with MH, walking on Patriots Path the only birds I heard were the woodpeckers high in the remaining trees. Many of the shrubs that lined the path were either ripped up by the county tree cutters or flattened by their machinery, so the white-throated sparrows that hid in these shrubs are gone.

I am hoping for a heavy snow to cover this mess, and that someone does something to remove the dead trees in spring and make this park meaningful to those who walk the path when the tree leaves sprout and the wildflowers are in bloom.

Feeding Time

Cardinal hogging the house feeder (Margo D. Beller)

Most mornings lately I have gone outside with the bird feeders around 7am when it is light but the sun hasn't risen high yet. Usually a male cardinal is sitting in the apple tree. When I prop open the screened door it starts to cheep to its mate, who cheeps back. It has figured out that when I open the door I will soon be out with the feeders - the suet on my right arm, the caged feeder in my right hand, the house feeder in my left. I go out and hang the house feeder on the first pole I pass, then walk to the other one and hang a feeder on each hook.

I go inside for the water cooler. By now the cardinal is on the house feeder but it flies off at my approach. I hang the water cooler on the pear tree and then walk back around the corner of the screened porch and close the door. Sometimes I stand outside and listen to the birds. Usually I hear white-breasted nuthatches and titmice nearby so I know they'll soon be at the feeder.

Other times I go on the porch and sit in my corner and watch the feeders.

As usual, the first birds were able to somehow communicate that food was available. But once all those birds start coming, it is interesting to see what gets to feed first and what forces them away from the feeder.

One reason I have two seed feeders out is the more open house feeder will accommodate two larger birds, one on each side. The caged feeder allows smaller birds to come into the protective cage (the cage is to protect the feeder from squirrels but I have seen small birds protected from predators), perch and eat. Chicadees and titmice will come, take a seed and leave. House finches will perch and keep eating until something, or someone, prompts them to leave.

A cardinal will sit at the house feeder and, like the smaller finches, eat until it is sated or spooked off. When a house finch or sparrow attempts to sit next to it, the cardinal will force it away. But if a comparably large bird, say a jay or a redbelly woodpecker, flies at the feeder, the cardinal departs. Jays and woodpeckers will sit a while but not as long as the thicker-billed cardinal or finch. When the big birds leave, the smaller ones can grab a bite.

Within the group, there is a pecking order. A male house finch will come to the house feeder. It might allow its mate to sit next to him but if another male house finch approaches it will fight it off if it is not the alpha bird but it will leave if the approaching bird is the alpha bird. The top bird always gets to eat. The same is true for other birds. One particularly snowy winter we had four pairs of cardinals coming to the feeder. The alpha pair always ate. If another cardinal was in the vicinity, the male would fly at it to force it away. Later, one of the others would come eat only to have the alpha male chase it off.

The only other thing I've ever seen that forces a cardinal off the feeder is if it is besieged by a lot of smaller birds that will harass it until it leaves

I don't know if this fighting would be avoided if I had many more feeders of different types out. Unfortunately, I don't have many feeders and all but one are not designed to accommodate a large bird like a cardinal.

Hummingbirds have a pecking order, too. When I had two females coming to the feeder in 2016 the more dominant one would always chase off the other. When a male showed up the alpha female would battle it, too, sometimes winning but sometimes flying off. Mind you, the sugar water feeder has several portals so they all could've fed at the same time and even brought over friends. But that's now how the bird brain operates.

Redbelly dominating the house feeder (Margo D. Beller)

The suet feeder draws woodpeckers. If the small downy is on the feeder and sees the larger hairy or redbelliy woodpecker approaching, it leaves fast. If a female downy is on the feeder and a male downy approaches, she's out of there, even if it's her mate. If two male downys are interested in the feeder, the alpha will chase the beta off, feed and then fly off, allowing the beta to eat - presuming the alpha male doesn't chase it off just because it can.

How is it determined which male or pair is the alpha and which isn't? That's another mystery better left to others to figure out.

Tweeting the Birds

We recently had two days of heavy rain and so I kept the feeders indoors because too much water can rot the seeds and then they are useless. After those two days I put the three feeders (two with sunflower seeds, one with suet) out and watched them from my kitchen.

When the snow is thick, food sources are thin aside from feeders.

For a long time there was no activity. Then a white-breasted nuthatch came to the house feeder, then a couple of titmice. Then nothing. A white-throated sparrow appeared on the flood wall and then flew to the base of one feeder pole to look for dropped seeds or scratch at the ground. Later, I would see jays fly to a seed feeder, chug down a few seeds and then fly off to trees to cache them in some hiding place for later eating. Then, a male cardinal flew in. Eventually a flock of house sparrows and house finches arrived en masse at the two seed feeders.

How did they know food was available? How do birds communicate that knowledge? I am no scientist but I have some theories based on years of observation.

and fro with seed, it will attract the attention of other
birds hungry for seeds - or for feeder birds. (Margo D. Beller)

Theory 1: The birds remember where there are food sources. If they don't find the feeders out one day, they come back and look again later that day or the next. In my yard they will find the feeders out most days until summer comes, when there will be plenty of other food sources.

If they find no food, they must seek it elsewhere. Birds must eat to survive and in winter they can't hang around the yard in hopes something may turn up. That also includes the hawks that know where there are feeders drawing the smaller birds they eat for their own survival.

Theory 2: A big, bright bird, be it a noisy one like a jay or a quiet one like a cardinal, is hard to miss. So if other birds are flying around the area and see that bright color at a feeder, they follow it, sorta like being followed on Twitter.

and pick up what other birds drop. (Margo D. Beller)

Theory 3: Speaking of tweeting, some birds are very vocal. There's the shrill "Thief!" call of the jay are the softer "dee, dee, dee" of the chickadee, the sharper variant of the titmouse and the "hank hank" of the white-breasted nuthatch. Other birds hear the calls and investigate. It's the same reason why, when I find a flock of titmice in the woods, I try to look at as many individuals as possible in case something different is flying with them looking for food. That way I've found myrtle warblers and gold-crowned kinglets foraging with the titmice and white-crowned sparrows with their white-throated cousins.

Theory 4: Birds communicate in a way we humans can't do ourselves or possibly understand.  

Likely it's a combination of all the above. Among each species during the breeding time the birds communicate which area is their territory, sing songs to attract mates or call to their young. But hunger is the main driver at this time of year. When there are few insects, birds must rely on weed seeds or those in feeders. Birds spend a lot of time and energy looking for food and in harsh winters many will die. So when they find food, whether they mean to communicate that information or not, the news gets around.

My job is to provide food and alert the birds so I can continue to hear their tweets.
