The Woodpeckers of Eliza Howell Park

In January 2018, I am starting my 14th year of recorded bird walks in Eliza Howell Park, but it doesn’t take all these records to know that, with so many birds migrating to warmer climates for the winter, January and February are the months with the fewest number of species. Even in the heart of winter, however, and far from any bird feeders, there are some species that I regularly see.

Two of the small number of species that I see every January are woodpeckers – the Red-bellied Woodpecker and the Downy Woodpecker. When first seen, the Red-bellied Woodpecker looks like it should be called “red-headed” (more about this below), but sometimes, as in this picture, the so-called red belly is noticeable.

The red-bellied is bright, loud, and large enough to be noticed easily, especially when there are no leaves on the trees. The smaller, quieter, less bright Downy Woodpecker is more likely to be lower and closer to the observer.

There are, in total, 6 different kinds of woodpeckers that occur in the park almost every year. Three are found year-round: Red-bellied, Downy, and Hairy Woodpecker. The Hairy Woodpecker (not pictured) is slightly larger than the Downy but otherwise looks almost exactly like it. It is less common at Eliza Howell, though it does breed here.

In the spring and again in the fall, the Yellow-bellied Sapsucker migrates through the area, seen for a few days only. It too has a questionable name – the “yellow bellied” part, not the “sapsucker” part. The yellow is somewhat visible in adults, but is not the most obvious characteristic. This picture is of an immature, without the red on the head or throat and without noticeable yellow, but it shows clearly the line of holes that the sapsucker makes to collect sap. It revisits the holes to lap up the sap and to eat any insects that may get caught there.

The most striking species of woodpecker to be seen in the park is also the most rare and the least predictable. The Red-headed Woodpecker is not very common in the Detroit area generally and shows up in Eliza Howell only about once a year, for a few days. In 2017, one was present in May (when this picture was taken) and one was also seen for several days in the summer.

(When someone asks why the “red-bellied” is not called the “red-headed,” I suggest that probably this bird has a priority claim to the name.)

The 6th woodpecker species in the park is the Northern Flicker. The flicker is a summer resident, arriving in the spring and leaving in the fall and is the fourth woodpecker that nests here. It is different from most other woodpeckers in that it often feeds on the ground, consuming large numbers of ants.

Woodpeckers typically drill holes in dead trees for nesting. These holes have quite small openings, but are deep. In 2017, I watched, over a period of days, as Red-bellied Woodpeckers and Northern Flickers drilled holes in trees about 100 yards apart. I watched as a red-bellied tried to drive a flicker away from the tree where the flicker was drilling its hole. I later watched as, in an different part of the park, red-bellieds and flickers were both carrying feed to their young in nests about 15-20 feet apart in the same dead tree. Interesting interactions between the two species.

In this picture, a Red-bellied Woodpecker is “spitting” out chips from the nesting hole it is making.

I started these thoughts by looking forward to seeing woodpeckers in winter. I end by looking backward to 2017. It is common, I suppose, for a nature student to think in terms of annual cycles.

VIEW FROM THE FOOTBRIDGE: October – December, 2017

The footbridge over the Rouge River (Main branch) is part of my regular walk in the park. During 2017, I got into the habit of taking a quick picture each time of the view from the footbridge, facing upriver. The pictures, in addition to being enjoyable views, help to refresh my memory on the timing of the seasonal changes in the park.

As a result of the cold spell in late December 2017, the river surface was frozen and snow covered by the end of the year.

The following pictures cover the last three months of the calendar year, in roughly 2-week intervals.

In Eliza Howell, most of the trees remain green in early October and slowly begin to change during the month.

The autumn look fully arrives in November, the month of the big leaf drop.

The first snows usually come in December, as they did in 2017.


December 12, 2017

The freezing over of the running water in December, as happened this year, is quite unusual.

I started taking frequent pictures from this viewpoint only in the middle of 2017. My hope is to document all 12 months this way in 2018.






After the Deer Died

On November 30, 2017, I first noticed the dead deer while I was walking through the bottomland in Eliza Howell Park, not far from where the two branches of the Rouge River meet. It was in the open, on the ground near the Main branch of the river. Based both on the animal’s appearance and on the fact that I take this route frequently, I think it had only recently died.

There were no wounds noticeable and I have no way of knowing what might have been the cause of death.

20171220_172147                           November 30, 2017

On subsequent walks, about every 2 – 3 days, I took a look at the carcass, wondering how long it might be before it was found by carrion eaters at this times of the year. Most of the Turkey Vultures had migrated a little earlier in the Fall, so it would more likely be a mammal.

The deer remained undisturbed as the weather turned colder.

20171220_172023                      December 7, 2017

When I checked on December 12, the carcass still appeared to be untouched, though it was a little difficult to be sure, since it was covered with snow.

Three days later, I came upon a very different picture. The carcass had been dragged several feet, torn open, and much of the meat taken.

20171215_102020                         December 15, 2017

There were many mammal tracks present, but the snow was all trampled down, the tracks were on top of one another, and it was very difficult to find a distinct and clear print. It looked like some animal or animals had had been working on the carcass for an extended period of time. The clearest tracks seemed to be about the size of those made by a medium-sized dog.

So what was it? Without any clear evidence, I can only speculate on what it might well have been, based on some key considerations. The fact that the carcass was moved several feet and that the carcass appeared to have had large chunks torn out suggests fairly large mammal(s). It is possible that small mammals might have been eating at the carcass as well, but this much consumption probably means something larger. It also might mean more than one.

My best guess is coyote. They have been seen in the park for some time, including recently, though I have no knowledge of the number. They are also known to be carrion eaters. They normally eat much smaller prey and do not attempt to bring down live deer. But a dead deer is different.  And, of course, coyotes can be in packs.

It is possible that it could be a pack of dogs. I have seen a few feral dogs in the park several times in past, but not recently, so I think it is more likely that this is the work of coyotes.

In my most recent visit, I saw that the skeleton had been further stripped.

Eliza Howell Park is a Detroit city park and observing some of what happened in the three weeks since the deer died provides another glimpse of the nature of urban wildlife activity.

Bald-Faced Hornet Nests

Bald-Faced Hornet Nests

Most visitors to Eliza Howell Park never see them, but there are many hundreds of Bald-faced Hornets here every summer. They are a native North American social wasp, not a true hornet, and build new nests each year. They are insect eaters much more than nectar collectors, so are not found on flowers as much as bees.

They do visit flowers more late in the season, however, and that provides the best opportunity to see what they really look like. The white on the face accounts for the “bald-faced” name (they are also sometimes called “White-faced Hornets”).


Bald-faced Hornets are best known by the nests they make, usually placed in tree branches and hidden in the leaves. In the last couple of years, I have kept a record of each nest that I have observed in the park. I don’t finish my count until sometime in December, when they are more visible with the leaves gone. Since paying closer attention, I have seen at least 10 nests annually – and have no doubt missed a number.

The nests are gray and sort of football-shaped, though more the size of a basketball, typically located high in a deciduous tree.


Fortunately, most years I find at least one that is low enough to be observed more carefully.


When these low nests are pointed out during nature walks before frost brings an end to hornet season, participants are often reluctant to approach too closely. It is a reasonable reluctance, since the greatest risk of being stung is from hornets protecting their colony. But it is not a big risk if one remains a few feet away.

The nests are made of paper-like material, wood fibers that have been mixed with saliva. The opening for going and coming is at/near the bottom of the nest.


Each colony is reported to have, at maturity, 100-400 individuals, made up of infertile female workers, reproductive females, and male drones. And, of course, a queen. Queens are the only Bald-faced Hornets that survive the winter, wintering in a sheltered place in trees or the ground. In the spring each queen that has survived begins to build a nest. She makes a few brood cells, deposits eggs in them, and feeds the larvae. The first brood then takes over nest building, food collection, and feeding.

When the nests are broken open after the hornets are gone, one can see the layers of cells that look like honeybee combs. There are tiers of combs within the thicker outer shell.


It is likely that more queens survive the winter in mild-weather years. This might account for the large number of nests I noted these last two years, following two mild winters. Or I may just be getting a little better about spotting the nests. It will be interesting to see what the findings are next year if this winter is a hard one.

Persistent Sumac Seed Clusters

Staghorn sumac is an attention grabber from July right through the winter. In the summer, the large red fruit cluster is already present; in the fall the leaves are a brilliant red well before the leaves turn on most other trees; in winter, the fruit clusters hang on when very little fruit remains on other trees in the park, providing sustenance both for birds and bird watchers on cold days.

Now, in early December, the robins that seem to have a particular sequence of moving from one type of berry to the next have arrived at the sumac in significant numbers. This is what they see up close.


Each of the little fuzzy fruits contains just one seed and the full cluster may contain as many as 700 seeds. The seed clusters grow at the end of stems on the deciduous shrubs or small trees, which may grow to some 20 feet. The plants grow in colonies or thickets and, in Eliza Howell, there is a grouping along the nature path leading to the river from the car loop.

The seed clusters grow in early summer, clearly noticeable by the fourth of July.

20171211_111502          July 5, 2017

Staghorn sumac got the name “staghorn” from the velvety covering of bare twigs in winter, which suggested (to someone) the velvet on new antlers. They have crooked, leaning trunks and large leaves. Some plants are male and some female; only female trees produce flowers and berries. The colony along the nature path is made up of female plants.

The fruit is edible and is used by some people to make a drink, which is compared to lemonade. Others dry and grind the fruit to use as a spice. The fruit is ready for human harvesting, should one want to do so, in late August or so. A variety of wildlife harvest the fruit later, often over the winter.

In September and October, the attractive red of the seed clusters is nearly overwhelmed by the brighter red of the leaves.

By the time December and the first snows come, the leaves are long gone and wildlife has begun to forage on the persistently standing seed clusters.

Since January 1, 2005, I have taken over 1000 nature walks in Eliza Howell Park in Detroit.


In getting started on this project, I was influenced by the advice of different naturalists over the years: if you really want to get to know nature well, take the same walk repeatedly. Good advice. I am finding that repeated visits to the same area — and good record keeping — do lead to a much better knowledge of the flora and fauna and to a much clearer recognition of the ways nature changes with the seasons.

Shortly before she died in 1964, Rachel Carson wrote an essay entitled “The Sense of Wonder,” reflecting upon a child’s sense of wonder and the risk that, without nourishment, it will not last until adulthood.

“A child’s world is fresh and new and beautiful, full or wonder and excitement. It is our misfortune that for most of us that clear-eyed vision, that true instinct for what is beautiful and awe-inspiring, is dimmed and even lost before we reach adulthood. If I had influence with the good fairy who is supposed to preside over the christening of all children, I should ask that her gift to each child in the world be a sense of wonder so indestructible that it would last throughout life, as an unfailing antidote against the boredom and disenchantment of later year, the sterile preoccupation with things that are artificial, the alienation from the sources of our strength.”

My childhood was many years ago, but my feeling of wonder and awe, my love and enjoyment of nature, grows the more I observe, learn, and understand. This leads naturally to a desire to share these experiences with others.

Eliza Howell Park is a Detroit city park, large (about 250 acres) and includes a diversity of habitats. The Upper and Main branches of the Rouge River meet in the park, with bottomland that is flooded on many occasions. A significant portion of the park is wooded and there is a large open area spotted with mature trees.


The park is close to home and provides an excellent opportunity for me to experience the natural world in its wonder and excitement and beauty, right in the heart of a major urban area. I continue to be excited by what nature presents in season after season.
