hairy woodpecker

by Roland D. Hallee

One of the things I enjoy doing at camp on a Saturday morning is grabbing a cup of coffee and sitting on my deck, focusing on the bird feeders. There is much activity around there, not just the birds, but the squirrels and chipmunks, and the occasional cat that comes around to harass the wildlife.

On a recent Saturday, I watched two hairy woodpeckers in particular – one male, one female.

I didn’t notice at first, but after a while it became evident the male, which was perched on a suet cake, would fill its mouth, fly down to the female that was sitting on a tree stump nearby, and transferring the food to her.

What a nice thing to do, I thought. The male providing for the female – I’m not being sexist here. Actually, upon closer observation, the female would then fly off into the woods, and return a short time later. This occurred over and over, again.

My deduction at that time was the female was, in turn, returning to the nest to feed the young. Adults regurgitate and insert food in the mouths of the very young. Food is transferred from adult to older offspring through open beaks with heads at an angle.

The hairy woodpecker, Euconotopicus villosus, is a medium-sized woodpecker that is found over a large area of North America. It is approximately 9-3/4 inches in length with 15-inch wingspan. With an estimated population in 2003 of over nine million individuals, the hairy woodpecker is listed by the International Union for Conservation of Nature (IUCN) as a species of least concern.

The hairy woodpecker was described and illustrated with a hand-coloured plate by the English naturalist Mark Catesby in his The Natural History of Carolina, Florida and the Bahama Islands which was published between 1729 and 1732. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he included the downy woodpecker, coined the binomial name Picus villosus and cited Catesby’s book.

The specific epithet “villosus” is the Latin word for “hairy”. Linnaeus specified the type locality as North America, with specific mention of Raccoon, New Jersey.

Adults are mainly black on the upper parts and wings, with a white or pale back and white spotting on the wings; the throat and belly vary from white to sooty brown. There is a white bar above and one below the eye. They have a black tail with white outer feathers. Adult males have a red patch or two side-by-side patches on the back of the head; juvenile males have red or rarely orange-red on the crown.

They have a somewhat soldierly look, with their erect, straight-backed posture on tree trunks and their cleanly striped heads. Look for them at backyard suet or sunflower feeders, and listen for them whinnying from woodlots, parks, and forests.

More than 75 percent of the hairy woodpecker’s diet is made up of insects, particularly the larvae of wood-boring beetles and bark beetles, ants, and moth pupae in their cocoons. To a lesser extent they also eat bees, wasps, caterpillars, spiders, millipedes, and rarely cockroaches, crickets, and grasshoppers. A little more than 20 percent of their diet is made up of fruit and seeds. My wife usually gets suet cakes that contain fruit, seeds and nuts, thus attracting the hairy woodpeckers.

Hairy woodpeckers have helped control pest outbreaks.

The hairy woodpecker is virtually identical in plumage to the smaller downy woodpecker. The downy has a shorter bill relative to the size of its head, which is, other than size and voice, the best way to distinguish them in the field. These two species are not closely related, however, and are likely to be separated in different genera. Another way to tell the two species apart is the lack of spots on its white tail feathers (present in the downy). Their outward similarity is a spectacular example of convergent evolution. As to the reason for this convergence, only tentative hypotheses have been advanced; in any case, because of the considerable size difference, ecological competition between the two species is slight.

The hairy woodpecker inhabits mature deciduous forests in the Bahamas, Canada, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Saint Pierre and Miquelon, and the United States. It is a vagrant to Puerto Rico and the Turks and Caicos Islands. Mating pairs will excavate a hole in a tree, where they will lay, on average, four white eggs. Hairy woodpeckers are common in mature woodlands with medium to large trees.

These birds are mostly permanent residents. Birds in the extreme north may migrate further south; birds in mountainous areas may move to lower elevations.

These birds forage on trees, often turning over bark or excavating to uncover insects. They mainly eat insects, but also fruits, berries and nuts, as well as sometimes tree sap. They are a natural predator of the European corn borer, a moth that costs the U.S. agriculture industry more than $1 billion annually in crop losses and population control. They are also known to peck at wooden window frames and wood-sided homes that may house prey.

Courting birds stretch out their necks, point their bills high, and bob their heads from side to side, flicking their wings as they circle a tree trunk. They also sometimes chase each other in fast, looping flights through the trees.

The entrance to the nest is about 2 inches tall and 1.5 inches wide, leading to a cavity 8-12 inches deep. The inside widens at the bottom to make room for the eggs and the incubating bird. It’s typically bare except for a bed of wood chips at the bottom for the eggs and chicks to rest on.

The female probably selects the nesting site, but both sexes work alternately at the labor of excavating the cavity. This work requires one to three weeks, depending on how hard the wood is; a cavity in the soft wood of a poplar, which is a favorite with this species in some localities, might be excavated in a very short time. A new nest may often be recognized by the presence of fresh chips on the ground around the tree, as the birds are not very particular about removing them.

Both male and female incubate and brood the young. The male sits on the eggs and broods the young during the night and the female relieves him every morning after sunrise. They alternate these duties throughout the day. Incubation last about 11-12 days and the young leave the nest in about 28-30 days after hatching.

We continue to watch the hairy woodpeckers, and the downy, come and go at the feeders, but we haven’t seen the exchange of food recently. Maybe the fledglings are now old enough to go out on their own.

Green June beetle (left), June Bug (right)

by Roland D. Hallee

Well, the first June bug of the year made its appearance at camp on Saturday, May 29, at 10:30 p.m. We were, after all, still in May. To date, however, I have only seen three. I remember one summer, around 2002, we were literally swarmed one night while sitting around a camp fire. We left outside lights on, and in the morning, I counted 53 dead June bugs on our deck. We have not seen nearly that many since.

Generally, June bugs, Phyllophaga, do make their appearance in mid- to late-May. So why are they called June bugs? It all depends on what you want to call them. They are also known as May beetles and June beetles. But, the name is derived from the fact that adult June bugs emerge from the soil at the end of spring or the beginning of summer.

Females bury their eggs just below the soil surface in the fall, they pupate and emerge in the spring. They hatch within three to four weeks and feed on grass and plant roots from several months to as long as three years. In spring, these grubs, as they are called, grow into pupae. Within three weeks, these mature into adult June bugs.

Grubs, when full grown, live in the soil and feed on plant roots, especially those of grasses and cereals, and are occasional pests in pastures, nurseries, gardens and golf courses. An obvious indication of infestation is the presence of birds, especially crows, peeling back the grass to get to the grubs. A way to test for the presence of these beetles is drenching an area of lawn with water, that will cause larvae to emerge at the surface.

Some small mammals, including skunks and moles, feed on the grubs.

The grubs have been known to attack vegetables and other garden plants, such as lettuce, raspberries, strawberries, potatoes and young ornamental trees. Maintaining a healthy lawn is a good step in deterring the grubs from establishing themselves.

Injury to the roots and rootstock causes small saplings and tender tap-rooted plants like lettuce to wilt suddenly or to show stunted growth and a tendency to shed leaves prematurely. Plants growing in rows are usually attacked in succession as the grubs move along from one plant to the next. Chafer grubs feed below ground for three – four years before changing into adult beetles.

June bugs are harmless. They do not bite, sting or spread disease. However, I did see one of my friends move faster than I have ever seen her move before, while sitting around a camp fire last weekend, when one landed on her. To be honest, it’s the natural reaction by most people, including yours truly.

Again, they are harmless, but because they are attracted to light they can make an evening sitting on your porch or deck a little unpleasant. Even if there is no light outdoors, they can be attracted to lights inside your home. I know at camp, when we’re spending time indoors after dark, they come “knocking” on our windows. The sound of June bugs buzzing and bumping against window screens in early summer is a very common occurrence over many parts of the U.S. Adult June bugs are extremely clumsy, especially in the air.

Scientists are still undecided on the precise explanation for this behavior. Several thoughts have been advanced, but no single theory has come about that can account for why so many different nocturnal insect species gravitate to sources of light. June bugs usually are a half-inch to an inch and a quarter in length. They can fly and you will find them swarming around street lights at night.

Now, let’s do some “did you know.”

• Exposure to light for longer intervals will kill June bugs. That is why you will find them dead in the morning under porch lights and windows.
• Don’t leave a window open during May-June period. They will enter your house and die, leaving you with a mess to clean up. If they do enter, remember, they don’t bite and are harmless, just annoying.
• There are over 200 different species of June bugs in the United States.
• A natural enemy of the June bug is the pyrgota fly larva, which feeds on the beetles, eventually killing them.
• The June bug larvae, called white grubs, are considered excellent fish bait, and are staples in the diets of native people in South America, Australia, and Asia.
• Have a pet lizard or toad? The beetles make excellent, tasty food for them.

There is another popular June beetle that’s active during the day. It is the Green June Beetle, and are found in our region of the Northeast, extending from Maine to Georgia and as far west as Kansas. These are not very good for the garden either. The head, legs and under-body is shiny green, while its wings are dull metallic green, with slight gold contrast to its sides.

Numerous songs have been written about June bugs, to include: “Junebug”, by The B-52s; “Junebug”, from the album Good Morning Spider by Sparklehorse; “Junebug”, by Robert Francis; “June Bug”, by Melvins; “Junebug”, by Stan Van Samang; and “Junebug”, by Kate Ryan.

So day and night, during early summer, these beetles can be destructive to vegetation, and just plain annoying to humans.

Whippoorwill

by Roland D. Hallee

While sitting on the deck at camp one lazy afternoon recently, one of our friends asked, “Why don’t we hear Whip-poor-wills anymore?”

Interesting question.

Besides the fact that whip-poor-wills are strictly nocturnal – that meaning they are active at night when I’m sleeping (something that seems to be happening earlier all the time) – whip-poor-wills are elusive.

Often heard but seldom observed, the whip-poor-will chants its name on summer nights in the eastern woods. Sometimes, the song seems to go on endlessly.

The whip-poor-wills, Antrostomus vociferus, have been made famous in folk songs, poems and literature for their endless chanting on summer nights.

Randy Travis features that fact in his song, Deeper than the Holler, with the stanza that goes:

My love is deeper than the holler, stronger than the river
Higher than the pine trees growin’ tall upon the hill
My love is purer than the snowflakes that fall in late December
And honest as a Robin on a springtime window sill
And longer than the song of a whippoorwill.

During the night, they will lay low and fly upwards to catch moths and other aerial insects.

At dusk and dawn, and on moonlit nights, they scurry out of their perches to sweep up insects in their large mouths.

During the day, they roost on the forest floor, or on a horizontal log or branch, and are very difficult to spot. Their brindled plumage blends perfectly with the gray-brown leaf litter of the open forests where they breed and roost.

Look for them in open understories. They can be found in both purely deciduous and mixed deciduous-conifer forests, often in areas with sandy soil.

Eastern whip-poor-wills migrate to Mexico and Central America for the winter, apparently traveling mostly over land to get there. In spring they arrive in breeding grounds between late March and mid-May. Since they are less vocal in autumn, less is known about their southward migration routes and timing, but they seem to leave between early September and late November.

The Eastern whip-poor-wills are medium-sized birds with a large, rounded head and a stout chest that tapers to a long tail and wings, giving them a distinctly front-heavy look. Like all nightjars, they are patterned with a complicated mottling of gray and brown, which camouflages them nearly perfectly with leaf litter and tree bark.

Nesting activities may be timed so adults are feeding young primarily on nights when the moon is more than half full, making it easier for them while foraging. Males sing at night to defend their territory and to attract a mate. They do not build nests in the traditional way. The nest site is on the ground in shady woods but often near the edge of a clearing, on open soil covered with dead leaves. They do not build a nest, but instead the eggs lay on the flat ground.

The entire state of Maine is part of the whip-poor-wills range.

But, getting back to the original question: Eastern whip-poor-wills are still fairly common birds, but their numbers declined by almost 3 percent per year between 1966 and 2015, resulting in a cumulative decline of 75 percent during that time, according to the North American Breeding Bird Survey. In some areas, parts of their range seem to have become unoccupied. Partners in Flight estimates a global breeding population of 2 million with 95 percent living part of the year in the U.S.

The decline in parts of their range is blamed mostly on open forests being converted to pasture urbanizing and agriculture. Although it’s not fully understood, the decline may also be caused by a general reduction in numbers of large moths and beetles.

The Eastern whip-poor-will is on the 2016 State of North America’s Birds’ Watch List, which includes bird species that are most at risk of extinction without significant conservation actions to reverse declines and reduce threats. Also, because whip-poor-wills often fly over roads or sit on roadways while foraging, they are also vulnerable to collisions with cars.

Restoration could occur when abandoned farmlands revert to forest.

So, on those quiet, moonlit nights around a campfire, listen off in the distance, and you just might here the call of the whip-poor-will.

Deer tick before and after engorging.

by Roland D. Hallee

There is nothing like beating a subject to death. But, in this case, it’s worth every word.

You have to be living in a cave not to know that deer ticks are at an all time high. They are everywhere. Friends and family have told me stories about their encounters with the pest, and they all have one thing in common: They have all had multiple numbers on them at one time.

Also, as you know, deer ticks are hazardous to your health, primarily because they are the carriers of the dreaded Lyme Disease. In the last decade alone, the population of ticks of all kinds has ballooned in the United States. The number of ticks that carry Lyme disease has been on the rise in the mid-Atlantic states, and has skyrocketed throughout the Northeast. It has gained a reputation as a serious health problem in many areas.

Only adult female ticks and nymphs can transmit infections through their bite. Male ticks attach, but they don’t feed or become engorged. Adult females have red and brown bodies and are larger than males. Nymphs are actively feeding between early April and early August.

Although not all deer ticks are infected with Lyme disease, you never really know. Only ticks that have fed on infected mammals are infected. About half of deer ticks are infected (usually white-footed mice can be other culprits).

a dog tick.

Deer ticks live two to three years, and in that time usually enjoy three blood meals. In the spring and summer of its second year, a nymph will take its second meal. They insert their mouth parts into the skin much like a corkscrew, which ensures them a nice tight grasp. They often take up to five days to complete their meal.

This fact is key to reducing panic when discovering a tick. An infected tick must be attached to its host for at least 24 hours, and up to 48 hours to transmit the disease. It’s the very reason for checking your body right away after any possible exposure to a tick-infested environment.

Deer ticks crawl. They usually grab onto people or animals that brush up against plants near ground level, and then they crawl upwards to find a quiet place for their blood meal. Although many sources will state that ticks don’t land on you from an overhanging tree branch, many people have insisted it has happened to them.

Ticks live in wooded, brushy areas that provide food and cover for mice, deer and other mammals. The ideal tick environment is humid. Your exposure will be greatest along trails in the woods and fringe areas between woods and the border, where they will wait patiently on the tips of vegetation for an unsuspecting host to walk by.

Life is too short to avoid the outdoors during our abbreviated spring, summer and fall. In Maine, that is about half the year. There is no need to be brave, just be smart: cover your body; wear repellant; check yourself for ticks, if you find a tick, remove it immediately; shower soon after being outdoors – last Saturday, after working around at camp, I found four ticks on the floor in the shower; throw clothing in the dryer, that will kill any ticks present; and finally, if you are concerned, don’t hesitate to contact your doctor.

The best way to remove a tick is to use fine-point tweezers and grab the tick as close to the skin surface as possible. Pull backwards gently but firmly, using an even, steady pressure. Do your best not to jerk or twist. Don’t squeeze, crush or puncture the tick’s body, the fluids inside may contain infection-causing organisms. After removing the tick, wash the skin and your hands thoroughly with hot soap and water. If any mouth part of the tick remain in the skin, leave them alone. They will be expelled on their own. It could take weeks. Trying to remove them will only cause you unnecessary pain.

For the deer tick, Ixodes scapularis, deer are the preferred host of the deer tick, but they can also be found in small rodents. After the female is engorged, the tick drops off and overwinters in the leaf litter of the forest floor. The following spring, she will lay several hundred to a few thousand eggs in clusters. They are very hardy creatures. Considering the mild winter we just experienced, they are active in record numbers. They will be active even after a moderate to severe frost, as daytime temperatures can warm them enough to keep them actively searching for a host. In the spring, they are one of the first invertebrates to become active.

It may be monotonous to keep hearing about the health hazards of being infected by a deer tick, but it’s one that needs to be repeated.

A vernal pool. (photo by Maine Department of Environmental Protection)

by Roland D. Hallee

Like an idiot, I decided to stop into the office on my way to camp on Sunday. However, every chore has its rewards. On our way to camp afterwards, I noticed a small vernal pool in its customary spot on the Cross Hill Road, in Vassalboro. It’s always there, but it’s usually dried up during the summer. Vernal pools are a very important occurrence in our ecosystem. Let’s take a look at what actually happens there.

Vernal pools, also called vernal ponds, are temporary pools of water that provide habitat for distinctive plants and animals. They are considered to be a distinctive type of wetland usually devoid of fish, and thus allow the safe development of amphibian and insect species unable to withstand competition or predation by fish.

Despite being dry at times, vernal pools teem with life when filled. The most obvious inhabitants are various species of breeding frogs and toads. Some salamanders also utilize vernal pools for reproduction, but the adults may visit the pool only briefly. Other notable inhabitants are Daphnia and fairy shrimp, the latter often used as an indicator species to decisively define a vernal pool. Other indicator species, at least in New England, are the wood frog, the spadefoot toad, and some species of mole salamanders. Certain plant species are also associated with vernal pools, although the particular species depend upon the region.

Vernal pools are shallow depressions that usually contain water for only part of the year. In the Northeast, vernal pools may fill during the fall and winter as the water table rises. Rain and melting snow also contribute water during the spring. Vernal pools typically dry out by mid to late summer. Although vernal pools may only contain water for a relatively short period of time, they serve as essential breeding habitat for certain species of wildlife, including salamanders and frogs. Since vernal pools dry out on a regular basis, they cannot support permanent populations of fish. The absence of fish provides an important ecological advantage for species that have adapted to vernal pools, because their eggs and young are safe from predation.

Species that must have access to vernal pools in order to survive and reproduce are known as “obligate” vernal pool species. In Maine, obligate vernal pool species include wood frogs, spotted and blue-spotted salamanders (two types of mole salamanders) and fairy shrimp. While wood frogs and mole salamanders live most of their lives in uplands, they must return to vernal pools to mate and lay their eggs. The eggs and young of these amphibians develop in the pools until they are mature enough to migrate to adjacent uplands. Fairy shrimp are small crustaceans which spend their entire life cycle in vernal pools, and have adapted to constantly changing environmental conditions. Fairy shrimp egg cases remain on the pool bottom even after all water has disappeared. The eggs can survive long periods of drying and freezing, but will hatch in late winter or early spring when water returns to the pool.

Not all vernal pool habitats are considered “significant”. In general, a vernal pool habitat is significant if it has a high habitat value, either because a state-listed threatened or endangered species, such as a spotted turtle, or a rare species, such as a ribbon snake, uses it to complete a critical part of its life history, or there is a notable abundance of specific wildlife, such as blue spotted salamander, wood frog, or fairy shrimp.

Do you have a vernal pool on your property and don’t know whether it is significant? The specific criteria describing a significant vernal pool are listed in DEP Rules, Chapter 335, and allow these resources to be identified in the field. Using these criteria, a person who has experience and training in either wetland ecology or wildlife ecology may identify and document a significant vernal pool; or the DEP may provide a written determination concerning whether or not a vernal pool habitat is significant.

“Significant vernal pool habitat” includes the vernal pool itself and the area within a 250-foot radius of the spring or fall high water mark of the pool, which is considered critical terrestrial habitat.

Since September 1, 2007, significant vernal pool habitat is protected by law under the Natural Resources Protection Act (NRPA). An activity in, on, or over these areas must avoid unreasonable impacts on the significant vernal pool habitat and obtain approval from the DEP, through a Permit by Rule or individual NRPA approval.

A permit by rule will be available if certain standards are met, and can be approved within 14 days. The standards do not create a mandatory setback or no-build zone, but do affect what can be done, so it is advisable to plan ahead. For more information on the NRPA, a copy of the rules addressing significant vernal pools, application forms, and related materials, see the NRPA page.

If you have questions, need hard copies of materials, or would like to request a field determination, contact your nearest DEP regional office, and ask to speak to the “on-call” person in the Land & Water Bureau, Division of Land Resource Regulation.

The Central Maine Regional Office is located at 17 State House Station, Augusta, ME 04333-0017; Phone: 207-287-7688 or 1-800-452-1942.
