Species Spotlight: Kirtland’s Warbler

By Ally Brown, MNA Intern

In some instances, the occurrence of a wildfire can mean devastation for species with restricted ranges and population; however, for one of Michigan’s rarest warblers, fires are crucial for building its niche habitat and sustaining the population. The Kirtland’s warbler is a member of the Parulidae or New World warbler family which measures about six inches in length and is distinguishable by the striking yellow plumage on its throat and breast and split white eye rings. As is the case with many of Michigan’s bird species, the Kirtland’s warbler nests in parts of the Upper and Lower Peninsulas during the summer months and makes the long journey to the south for the winter months – in this case a 1400 mile trip to the Bahamas. While it may seem as though this long-distance flight would be the toughest part of life as a Kirtland’s warbler, the largest challenge this population faces comes from its time up north.

Although not immediately obvious by the forested landscapes known today, Michigan’s history is one of expansive barrens and frequent fires. Many grassland and barren species adapted to this cycle of burnings, one of which is the fire dependent jack pine tree. Heat is necessary to the lifecycle of the jack pine, as it promotes the tree’s cones to fully open and successfully germinate. With the suppression of fire, young stands of jack pine become less and less common and old stands grow dense and tall, losing their lower branches due to lack of sunlight. The degradation and succession of the jack pine ecosystem reasonably follows this lack of fire, but what was not suspected was the subsequent decline in the Kirtland warbler population.

According to the DNR, Kirtland’s warblers nest in young jack pines on branches that essentially touch the ground, where they can hide their nests among dense thickets of pine and grasses. In order for these conditions to occur, the pines must be young and small so that sunlight can reach the ground and keep the lower branches of the trees alive. This also requires the occurrence of frequent fires to remove older trees in exchange for the germination of their cones. Without these fires, the selective female warblers will refuse to nest and, according to the Cornell Lab of Ornithology, only single male warblers will continue to live in the old, successional stands. Another major benefit of hiding nests in the lower branches of young jack pines is protection from the parasitic brown headed cowbird, which will remove warbler eggs from the nest and replace them with eggs of its own.

Today, with the importance of fire and the jack pine to Kirtland’s warbler populations known, effort is being placed to conserve this habitat and the warbler population. Several of MNA’s sanctuaries house populations of jack pine, including Redwyn’s Dunes Nature Sanctuary, and today birders can view this rare bird through tours given by the Kirtland’s Warbler Recovery Team. According to the DNR, the best way to support this endangered species is to educate yourself and those around you through research or attending birding tours, as well as to donate to local organizations, like the Michigan Nature Association, dedicated to protecting and rebuilding the warbler population.

Species Spotlight: Lake Sturgeon

By Michelle Ferrell, MNA Intern

lake sturgeon

Though Lake Sturgeon make look intimidating with their armored, angular bodies, it may be fair to classify them as gentle giants of the Great Lakes. They have lived in this region for around 10,000 years – and have existed for around 136 million. Capable of living for 150 years or longer, these ancient freshwater behemoths are the longest-lived of Michigan’s fish species, as well as the largest, having been known to reach lengths of 8 feet and weigh several hundred pounds. It may technically be female sturgeon which are the longest-lived Great Lakes fish, though, as they can outlive males by as much as a century!

Sturgeon are cartilaginous (non-bony) fish with torpedo-shaped bodies. Instead of scales, they have a kind of armor in the form of bony scutes that cover their bodies. Juveniles may be gray or brown, and appear more angular, while adults tend to be lighter in color and may be gray or olive. The growth rates of Sturgeon are highly variable, but cleaner, more temperate waters and greater food availability offer ideal conditions for these fish to grow large.

Sexual maturity in males is reached anywhere from 8 to 22 years for males and 14 to 26 years for females. Spawning occurs in early spring, usually from April to June, when water temperatures warm to 53-64° F in clean, shallow waters and fast-moving stream rapids. Though they accomplish this impressive feat on average only once every 6-7 years, females lay millions of eggs when spawning – that’s an average of 5,500 eggs per pound of fish!

Once, the range of lake sturgeon extended from parts of Canada down to Alabama, and populations in the Great Lakes region were estimated to have numbered in the millions. However, only remnant populations remain. Historic overfishing in the 19th and 20th centuries nearly led to the extinction of lake sturgeon, as well as pollution and habitat loss from dams and deforestation. They are now listed as Endangered, Threatened, or Special Concern in all but one of the states throughout their range.

Thankfully, Michigan sponsors efforts to protect sturgeon and restore parts of their habitat. Their spawning period is an especially crucial one, as their preferences for shallow waters make them vulnerable. If you happen to come across sturgeon in the wild, count yourself fortunate to have witnessed these living fossils. Learn more about this iconic Great Lakes species from the DNR website.

Join MNA on Sunday, October 8 for our annual Sturgeon Sprint Family Fun Run & 5K in Detroit! Run along the scenic roadway of Belle Isle State Park. The fee for adults is $25, and $10 for kids. As always, a t-shirt is included and all runners receive a participatory medal! Proceeds will promote efforts to protect the Lake Sturgeon. Register online or contact Jess Foxen at jfoxen@michigannature.org for more information.

A pre-party will be held at Blaze Pizza, located at 3129 Fairlane Drive, Allen Park, from 3-7 pm. Present this flyer with your fast-fire’d creation and Blaze will donate 20% of their proceeds to MNA! Happy running!

Fall 2017 Michigan Nature Magazine

Fall means back to school, and that new reality brings a seasonal change to the daily migration routes for many Michigan families.

Fall is an especially great time of year to connect kids to nature and the incredible changes that unfold. As students – and their parents – adjust their new clocks and adapt to a new school year, here at MNA we are working with teachers to enrich their student’s classroom learning by using MNA nature sanctuaries as living laboratories. Our schools-to-sanctuaries initiative is creating exciting new partnerships across the state, like the one described by Addison High School teacher Aaron Wesche in this issue’s Q&A (p.33).

Cooler temperatures and decreasing daylight are signals for migratory birds and insects that it is time to leave their northern breeding grounds for warmer winter climes. Some make extraordinary difficult journeys to do so. One of the most astonishing dramas in nature is the annual Monarch butterfly migration from the northern U.S. to a tiny strip of forest in Mexico. Take yourself to a Great Lakes beach or an MNA nature sanctuary with open fields this time of year and wait and watch. You’ll very likely see one of these stunning and fragile beauties flit by as they make their miraculous journey to Mexico.

Sadly, those who have spent a lifetime watching the Monarch migration for the sheer joy of it will tell you they don’t see as many butterflies anymore. Scientists who study the Monarch have confirmed this. In this issue, noted Michigan author Bill Rapai tells the story of how the Monarch migration is now in serious danger of disappearing (p. 18).

The good news is that we can play a role in helping this extraordinary migration (while also helping other declining pollinators). We know that many of our nature sanctuaries provide necessary places for fuel and rest for Monarchs on their journey, but we also know much more needs to be done.

With your continued support MNA will be working to create more Monarch-friendly habitat within our statewide network of sanctuaries; help inspire the next generation to care about Michigan’s natural wonders like the Monarch butterfly through our education programs; and coordinate our work on Monarch conservation with the work of like-minded groups in Michigan, across the Midwest, and Mexico.
