Hazards to birders in Michigan

Hazards to birders in Michigan are few and include biting insects, traffic, theft in urban areas, certain weather conditions, Poison-ivy and Poison Sumac, Black Bears, and even Moose in some areas, and, in a very few areas, a rattlesnake species. Biting insects are by far the most frequent hazard that birders may encounter. From May through September, mosquitos will be present in any wooded or wetland area statewide. 


Swampy situations and more northern areas are often the worst, and some may want to consider head nets in these areas. Every birder should consider using insect repellent, as mosquito-borne diseases such as West Nile Virus have been detected in Michigan. In more northern regions, Black Flies can be a problem in the summer months (June–August), and in some boggy and swampy areas, there can be swarms of them.


Insect repellent is recommended. Ticks are found statewide, most often Wood Ticks and precautions should be taken when walking in tall grassy areas. The much tinier Deer Tick, while less commonly encountered, is a more significant problem as it carries Lyme Disease, which has occurred in Michigan. Tucking your pant legs into your socks and using insect repellent on the socks and wearing long-sleeved shirts in these areas is usually sufficient protection.


Chiggers are relatively rare in Michigan but do occur in summer in drier prairie areas of the southeastern and southwestern corners of the state, though they are infrequently encountered by birders. Toxic vegetation in Michigan consists of two plants, Poison-ivy and Poison Sumac, both of which cause skin irritations and rashes with intense itching. Some people are immune to the effects of the plants’ oils (urushiol), but as one of the editors recently discovered, this immunity is not necessarily permanent!


Poison-ivy is found in shrubby and wooded areas statewide and is quite common. In northern areas, it is often little more than a ground cover, when is sometimes called Poison Oak (which does not occur in Michigan), but in the southernmost areas, it is often a vine that can be as thick as your finger to, exceptionally, as thick as your forearm. Some birds, most notably Northern Flickers, relish Poison-ivy berries in the fall.


Learn to recognize the “hairy” tendrils on the vines of this plant, and the leaf arrangement and shape—”leaflets three, let it be”. Virginia Creeper is similar to Poison-ivy, but typically has five leaflets, a woody vine without hairy tendrils, and often grows even larger. The distribution of Poison Sumac is quite patchy, confined to the Lower Peninsula, and typically restricted to the swampy or boggy lake and pond margins, and is infrequently encountered by birders. The appearance is similar to the very common Staghorn Sumac, but has fewer shinier leaflets, which also lack serrations on the edges.


Staghorn Sumac is infrequently found in the same habitats as Poison Sumac. Black Bears occur through the northern Lower Peninsula and the entire Upper Peninsula, though they are not as common as in many western states, and they are rarely a problem. Bears may be encountered at campgrounds, and precautions should be taken to properly stow food so as not to attract them. In a few areas of the western Upper Peninsula, Moose has been reintroduced and could possibly be encountered, though they are still somewhat rare. Never approach a Moose closely on foot, and never get between a female and her calf.


Michigan has a single venomous reptile, the Eastern Massassauga, a small rattlesnake. The Eastern Massassauga, a Threatened, protected species in Michigan, occurs in the southern two-thirds of the Lower Peninsula and is rarely encountered. It inhabits swamps, bogs, and some marshes, and its distribution is quite patchy. Sites, where the presence of this snake is known, are noted in the text.


Being one of the smallest of rattlesnakes (up to 30" and usually much smaller), the bite of the Eastern Massassauga is most serious only to small infants or the elderly (rarely fatal) but can cause considerable pain and illness even in a healthy adult. Most bites from this relatively even-tempered snake are caused by people attempting to move the snake off a trail.


The snake, while generally tolerant, interprets too much of this activity as harassment and reacts defensively as it would to any threat. The best strategy is to walk around the snake, giving it a wide berth, enjoy the fact that you’re experiencing something that few Michiganders ever have, and by all means leave the snake alone! Certain areas in Michigan, as in all states, are prone to crime.


No birding areas are located in high crime areas, but there are a few where caution is advised, some surprisingly far from urban areas. These few areas are noted in the text. By far the most frequent crime that birders fall victim to, and even this is rare, is theft. Precautions consist largely of making sure you do not leave valuables in sight inside your car. Take your valuables with you, or lock them in the trunk. The few weather-related hazards include snow and cold, thunderstorms, and tornados.


Severe winter conditions can be encountered by birders visiting the Upper Peninsula and even the northern Lower Peninsula, and appropriate precautions should be taken. Driving on unplowed roads is not advised, as getting stranded in deep snow miles from help, with temperatures below zero, could develop into a life-threatening situation. Serious winter trips into these regions mean bringing blankets, candles, extra food, etc. Wind, in combination with cold temperatures, will create wind chill that can cause frostbite on exposed skin in minutes.


Sometimes winter wind chills as low as -20 to -50°F can occur anywhere in the state, most often in the UP. Dangerous thunderstorms and tornados (most frequent in June and July) are easily avoided by birders, as such conditions are usually apparent. In early spring, many of the less-used backcountry roads can become very wet with deep mud-holes that can entrap the unwary birder.


Many of these same roads in sandy areas, particularly those used by ORVs, can be quite soft, sometimes resulting in standard cars becoming stuck. Thoroughly checking out these potentially hazardous conditions may prevent a long, expensive trip to the nearest towing facility. In May 2004, Michigan law was changed regarding pedestrian travel over the state’s beaches.


The law, which applies to beaches on private property, states that private landowners with beachfront property control all the land up to the water’s edge. Thus, the only way to avoid trespassing under this new law is to be in the water! It is unclear how this new law will play out, but for now, it is wise to exercise extra caution when walking on Great Lakes beaches in Michigan to avoid trespassing on private property.


Under most conditions, the breakwalls, piers, and jetties along the lake shorelines are reasonably safe for birding, though it is always a good idea to dress warmly. Be careful where you walk, as large cracks or uneven places in the concrete could cause injury. Dangerous conditions exist on all Great Lakes breakwalls during strong winds and icy conditions. DO NOT walk out on a breakwall if waves are breaking over it, or if it is icy. Falling off the breakwall into the water could result in drowning in strong currents in windy conditions, or death from the rapid onset of hypothermia during icy conditions.
