Wild Goose Watching

Winter's not gone yet, if the wild geese fly that way.

-- William Shakespeare, "King Lear"

A cool October Sunday morning and I am sweeping. The trees are starting to color and the leaves are falling in earnest when shaken by the breeze coming from the north. It is blessedly quiet, only a couple of dogs barking in the near-distance dog park, the occasional jay or crow calling and the sound of my broom brushing together the acorns on the patio. The clouds are being chased across the sun. 

It is slow right now, no runners or dog walkers or kids yelling. No one heading to church or VFW pancake breakfasts or pick-your-own apples or cross-country running matches. I fully expect to soon hear this activity as well as neighbors using their blowers on the fallen leaves (fighting the wind blowing more down) once it is the legal start time for noise on a Sunday. (I hear them now as I write.)

There are fewer acorns to collect this time than last time but they are still falling in smaller numbers on the roof of the enclosed porch and in the lawn, where I have to step carefully if I am doing any yard work. I raked locust pods from the front lawn before our mowing guy came through, and expect to do it again before he next comes. The yew hedge, I notice, has dropped its uneaten red berries on the edge of the driveway, and I push those away with my broom, too.

"Moongooses" by Wildlife Terry is marked with CC0 1.0.

I enjoy the quiet, but then I hear the distant honking. I stop and look at the sky where it is not blocked by trees, and I wait. 

This time there are only about 40 Canada geese very high up. Most of them are in a long V while some are in an uneven line to the V's left. They are flying southeast because at this time of year they are migrating to their winter grounds. I always stop to watch the flying geese when I hear the honking. 

It is not as though these are rare migrants. In my part of the world they are far too common. Decades ago a few did not migrate. They found parks, office campuses and backyards full of food, the weather not too bad and few to no predators. They stayed, they bred, they created a large number of little fuzzballs (one brood each year can include from two to eight goslings) that start off looking so cute but then grow to look just like their parents. Then the cycle begins again.

Canada geese, whether they are wild or domesticated, are protected by treaty. They can't be hunted except during specific state hunting seasons. The hunters must be licensed. Those hunts help keep down the population. But people in cities are horrified when officials order a goose "culling" to cut down the number befouling the parks. They rally, they protest. These are people who do not hunt and do not see an ecological imbalance, they see "nature" being destroyed for (to them) no good reason.

At their worst, grass and ponds are green with goose excrement. When the young are small the goose parents, which mate for life, are extremely protective and will attack a person who gets too close. Most of the time when I hear honking it is from geese that are in the nearby community garden, or the pond a quarter mile away. When they fly they are not heading north in the spring or south for the winter, they are rising from one pond and heading to another so they can continue eating. When people walk their dogs at the community garden the geese take off with a noisy clatter, scattering in many directions but then meeting up later. (In that they are like another now-common pest where I live, the deer.)

How I see Canada geese all too often. (Margo D. Beller)

But this morning's calling geese are wild geese, doing what wild geese are supposed to do - get out before winter comes and the lakes and ponds freeze.

Why are they flying in a V? According to an article by the U.S. Library of Congress:

First, it conserves their energy. Each bird flies slightly above the bird in front of them, resulting in a reduction of wind resistance. The birds take turns being in the front, falling back when they get tired. In this way, the geese can fly for a long time before they must stop for rest. The authors of a 2001 Nature article stated that pelicans that fly alone beat their wings more frequently and have higher heart rates than those that fly in formation. It follows that birds that fly in formation glide more often and reduce energy expenditure (Weimerskirch, 2001).

The second benefit to the V formation is that it is easy to keep track of every bird in the group. Flying in formation may assist with the communication and coordination within the group. Fighter pilots often use this formation for the same reason.

If I am outside at the right time of morning on the right day in the right month, I can see multiple large Vs of geese, sometimes with hundreds of birds. This is an easy type of bird watching, just as being on a hawk platform and watching the migrating eagles, buteos, accipiters and falcons heading south over mountain ridges each autumn is easy birding. The birds fly in daylight and are big and easy to see, not like the small warblers jumping around quietly from branch to branch in still-leafy trees. Finding warblers in autumn is a challenge, but there are times I don't want a challenge. I just want to stand still on a quiet Sunday morning and look up at a V of wild birds flying away to the south.

Earthbound, I envy them. 

Cleaning Up After The Trees

 In October, a maple tree before your window lights up your room like a great lamp.

-- John Burroughs

October, the year's tenth month (with a name reflecting when it was the eighth month under the Roman calendar), is a time of transition. October is when you really notice it is darker later in the morning and earlier in the evening. October is when the weather switches from over 80 degrees one day to cold enough to break out the winter quilt the next.

what I have been sweeping up from the patio.
(Margo D. Beller)

October is when the pumpkins, squashes and dried corn threshes start showing up on suburban doorsteps with the September mums. You realize you are closer to the end of the year than the beginning, and you wonder if there will be more snow this year than last.

For me, October is when I start thinking about bringing plants back into the house and putting up storm windows. I notice fewer catbirds in the yard but hear white-throated sparrows. Raptors are on the move and I see skeins of Canada geese overhead, heading south. Soon I will be putting out more seed feeders and suet.

The "flowers" on the ornamental grasses are the
best they've been in years. (Margo D. Beller)

Yes, there are also the colorful autumn leaves that send people into their cars to drive north to Vermont or the Adirondacks or other such hotspots. In my yard the red leaves of the maple and the dogwood, the brown of the white oak, the yellow of the elms and the scarlet of the red oak will be very pretty, at least for a short while. And then the usual October winds will blow them off the trees to become that much more mess to be cleaned up. 

Yes, October is when things start falling out of trees.

This week, the summery days gave way to foggy, cool nights and my sleep has been continually interrupted by the sharp rap of oak acorns falling on the enclosed porch's roof. The squirrels are foraging in the trees by day, and by night the trees must figure it's time to spread some seeds all over the ground beneath them to perpetuate the species. 

The dropping does not cease. Sometimes, if the acorn hits a metal gutter, it can sound like a gunshot. Most of the time, however, it sounds like someone is banging into something in the night.

Two types of nuts falling from my trees. (Margo D. Beller)

Despite the noise I am glad I have this roof over my porch. I have friends with open decks who are forced to huddle under the picnic table umbrella as acorn bombs drop from the sky. When my in-laws lived in New Jersey the big oak next to the driveway regularly pitted the old family sedan, making it look like it had been in a hail storm.

My problem is when the acorns make it hard to walk to the feeder pole or the water dish. That is why I have gone out on the patio three times - so far - to herd marble-like oak acorns with my broom into my large garden pail, lug it to a corner of my yard and dump it for any squirrel, chipmunk, deer, woodpecker, jay or crow that might want a snack.

But there are many, many more acorns all over the lawn, and even when I am drinking coffee on the porch, congratulating myself on a job well done, I hear the acorns continuing to drop. It will be like this for weeks.

What hangs up will eventually come down. (Margo D. Beller)

It is not the tree's fault, of course. It is just trying to survive. If the trees were in the woods this would be a barely noticed process. But these trees are not in the woods, they border the property of my suburban yard. And so I notice big time.

There are some years when there are many more acorns than there are squirrels, like this year. There are some years there are many more squirrels than there are acorns, like last year. This boom and bust is not as random as it may seem.

Acorns are seeds and they are dropped by the oaks to make more trees. But the seeds are also food. The more food there is, the more an animal eats and then the more it breeds. More animals mean more food is needed. When seeds are plentiful, everyone is happy - the animals and the trees. But if there are too many animals and not enough seeds, there will be a decrease in new trees. That seems to prompt trees to shut down making seeds, which then cuts back on the animal population because there is less food.

The technical name for this boom and bust cycling is masting. According to the New Jersey Conservation Foundation, mast is the fruit of forest trees, in this case acorns. During "mast" years, the trees "go into overdrive, producing enormous amounts of nuts." Then comes the bust, a year or more when there are very few nuts produced.

How the pretty autumn leaves will eventually end up...
(Margo D. Beller)

Why does this happen? Again, from the Foundation:

Scientists don’t know the exact trigger for mast years, but it most likely has to do with climate events in past stressful years. Trees may produce an abundance of offspring as a hedge in case the stressful times continue. Stressors may include droughts, heat waves, or cold spells.

I'm no scientist but I know there is a lot of wacky stuff going on in the atmosphere around the world - a rare tropical storm in California, abundant wildfires in Canada, deadly floods in Libya. We are on pace to have the hottest year on record after having the hottest past few months on record.

... and the pods. (Margo D. Beller)

Closer to home, this has been a very wet year. The same abundance of rain that has helped keep my dogwood tree alive, produced the "flowers" on my ornamental grasses for the first time in years and kept the spider mites and white flies off my flowers likely produced favorable conditions for the oak trees to produce acorns after a year when not many were produced. The old trees have grown and now more of their branches are above the porch roof, something I didn't notice until the acorns started raining down heavier than usual this year. 

The oaks are not alone, of course. Many other trees are now dropping their seeds, including the bane of my existence, the black locust. October is when I notice how many of the long, black pods are hanging, waiting for some signal or gust of wind to drop like a blanket over my lawn. Like the acorns, eventually they will all come down and be swept away, to be forgotten until the next October. 

Where Are The Birds?

The other day, the one day last week that was not cold, dark and rainy, I went for a long walk as much for exercise as for seeing what birds were around. I went to my usual patch, a linear park not far from me called Patriots Path. 

Patriots Path (Margo D. Beller)

After more than an hour of walking and listening to jays, robins, cardinals, catbirds, Carolina wrens and many other of the more common birds of the area, I was on my way back to the car when I was stopped by a woman walking her dog. "Are you looking for birds?" she asked, looking at my binoculars.

This has happened before, and I wondered if she was going to tell me about seeing some strange bird she couldn't identify. But no. What she said was, "Have you noticed there are fewer birds? Is something environmental happening to them?"

I wasn't sure by "environmental" whether she meant chemicals killing birds, which is certainly a major hazzard. So are cats, both those domestic ones allowed to roam outdoors by their owners and the feral ones I sometimes see passing through my yard.  

To her I blamed the weather, specifically Tropical Storm Ophelia and other storms that have blown through the eastern United States. When Ophelia was going up the coast, the winds were mainly out of the east. If a bird was trying to head south, I said, it would likely go west to avoid the headwinds. "The midwest is probably seeing a bumper crop of birds," I said.

She seemed reassured and thanked me.

A potential bird hazzard, if allowed outside.
(Margo D. Beller)

After I got home I thought about our conversation. Besides chemicals and cats there is the possibility of birds being blown into trees by high winds. Or hit by cars as they fly low across the road (robins and sparrows are prone to this, I've found). 

Then I found this article, which gave me another perspective - a hurricane - Lee - so strong the birds were blown across the Atlantic Ocean to Europe, where "common" birds I find daily in my travels are "rarities" over there. Lee, a category 5 storm, blew hard along the East Coast, and I expected to see reports of birds showing up in places where they are normally not found.

That happened with flamingos after Hurricane Idalia, when the pink birds associated with Florida and the tropics started being reported in Wisconsin, Texas and Ohio. One area's "common" is another's "rarity," even within the United States. But I never expected birds to be blown so far to the east by Hurricane Lee.

So are there fewer birds? Depends on where you go. Back in my area I have found lots of the more common birds and, once in a while, a migrant bird passing through on its way to its southern wintering grounds. But that is because I have taken myself outside to look for them. I don't usually go birding in the rain. I don't even put out feeders in the rain. And we've had a ton of rain lately.

Maybe the woman I spoke to sees fewer birds now than before because she is out more often with her dog in all types of weather and has more of a basis of comparison. Maybe what she sees confirms what Audubon has warned about the decline in U.S. birds.   

Where are all the birds? I have to believe they are still out there. You and I just have to go find them.
