At our Monarch Mania program yesterday at Mentor Marsh, we celebrated these wild winged creatures who take an amazing migratory flight to overwinter in the mountains of central Mexico. We learned more about them, threats that harm them, how we can support Monarchs and other invertebrates plus got to tag and release a wild Monarch, too! Truly astounding!

To learn more about the natural history of monarch butterflies as well as more information on tracking them with tags, see links in comments.

Happy weekend! What do you have planned for this weekend? Looks like a beautiful weather weekend for exploring!

Hope you can join us tomorrow for our Monarch Mania program for an exploration of monarch butterflies, including their life cycle, natural history, and how we can help support ecosystems that help monarchs and more.

Tomorrow, we’ll talk about host plants and nectar plants, and why these habitat components are critical for monarchs. Learn how these butterflies are tagged—you can even join in as we tag and release monarchs. Then we’ll go on a hike to see if we can catch and tag some wild monarchs in the Marsh, too!

Just in time for fall bird migration, Spicebush berries are ripening in our woods. Spicebush is a common understory shrub whose “habitats include rich deciduous woodlands, wooded bluffs, bottomland forests along rivers, wooded slopes (usually toward the bottom), and gravelly seeps in shaded areas. While Spicebush is fairly shade-tolerant, it benefits from occasional disturbance that reduces the dense shade of some canopy trees, particularly Sugar Maple, American Beech, and similar trees…This shrub prefers dappled sunlight to medium shade, moist to mesic conditions, and a fertile loamy soil with decaying organic matter. It is adaptable to cultivation in yards and gardens.” (IL Wildflowers).

Spicebush’s fall foliage is a rich yellow that makes this understory shrub’s presence well known in autumn woodlands, just like its conspicuous yellow flowers in the springtime, too.

Not only does this shrub offer floral resources for many early spring flying bees, its foliage supports caterpillars of several moth species as well as Spicebush Swallowtail caterpillars. “Among vertebrate animals, many species of birds consume the red fruits occasionally, spreading the seeds of this shrub to new locations (see link in comments to Bird Table). This includes such birds as the White-throated Sparrow, Veery, Grey-cheeked Thrush, Wood Thrush, Eastern Kingbird, and Red-eyed Vireo” (IL Wildflowers).

Do you have this powerhouse shrub growing in your landscaping or on your property? What else are you finding in your outdoors explorations?

Ah, summer! We’re at this fantastic time of year in late summer when we’re observing Monarch butterflies that are part of the generation that makes their amazing migration to overwinter in the mountains of Mexico. You can join us for our yearly Monarch Mania program on Sunday to learn more about this migratory phenomenon!

We’re meeting at the Mentor Marsh Nature Center at 2 pm for an exploration of monarch butterflies, including their life cycle, and natural history. We’ll talk about Monarch tagging for tracking their migration and even try our hand at tagging some butterflies.

Happy ! Time to crawl out of the covers and enjoy this beautiful summer day!

You’re certain to see a Painted Turtle or two along the Wake Robin boardwalk and keep your eyes out for a Blanding’s Turtle, too! That’d be an extra special sighting. Read more about the Museum’s Blanding Turtle project at the link in comments.

This marsh sure is marvelous!

Enjoy these marsh treasures as viewed through Nan’s lens! Mentor Marsh’s Shipman Pond is truly a hotspot of avian activity. Shipman Pond, the open water habitat in the northeastern end of the marsh, is bisected by the Headlands Road bridge. You can catch glimpses of it from SR 44 just south of the state park as well as from the western side, on foot from our Zimmerman Trail. It’s a hotspot year-round as birds find refuge here, foraging and recharging or a hotspot for birds who nest here.

Thanks, Nan, for sharing your favorite place and the sights you see there!

Birding is starting to heat up as we inch towards the changing season. Feels like fall this morning, doesn’t it?

The prediction is that the first big wave of migratory songbirds will pass though our area this weekend. If you haven’t followed migration and it fascinates you, check out Cornell’s Lab of Ornithology, BirdCast. Their tagline is showcasing the spectacle of migration. “Curious about when, where, and how far birds migrate? Want to watch migration in your area as it happens? Find all this and more...” at the link in comments.

Meanwhile, get yourself outside! This American Goldfinch was feeding along the Wake Robin boardwalk in the marsh last week. Our trails are open dawn to dusk, every day! See link in comments for more information on trails and general marsh information.

What are you observing in your outdoor explorations?

Happy summery sunny Sunday morning! These bright yellow flowers sure do connote summer and sunshine, don’t they?!

Summer wildflowers are indeed in full glory. Squeeze out some time to treat yourself to a guided hike this afternoon to explore summer wildflowers! Or check them out on your own! Our trails are open dawn to dusk, year round. See link in comments for a map of our trails.

We’ll see what summer wildflowers are blooming in our native landscaping, our prairie, and Mentor Marsh. Our diverse habitats support a great number of plants, and summertime is the perfect time to enjoy these beautiful blooms!

A sand sculpture of bird-watching turtles that looks out at Museum's Mentor Marsh State Nature Preserve from Mentor Lagoons? Sounds like something straight out of a dream! 🐢💭

The Museum's Exhibit Specialist, Carl Jara, is also a sand sculptor with more than 25 years of experience. Carl says it takes about 30 hours to bring a sculpture to life.
We are so honored to have two outstanding pieces of art inspired by Mentor Marsh. If the weather permits, these sculptures should be standing for about a month, so be sure to check them out while you can.

Happy ! Oh, summer! How do I love thee! Summer wildflowers are peaking and we’ll be hiking to explore what’s in bloom in and around the Marsh on Sunday. What a treasure hunt! So much life is supported by the diversity of blooms!

See link in comments for the Cleveland Museum of Natural History’s website of upcoming Mentor Marsh programs. Hope you join us!
