Fall on the Prairie

While summer blooms elsewhere are winding down, the Dixon Prairie is still alive with many fall flowers.

Asters, sawtooth sunflowers, gaura, and goldenrod are going strong. All of them are abuzz with bees and other insects. Grasshoppers dance from plant to plant. Butterflies fuel up for a last fling or long journey.

Grasses, some with tiny fragrant flowers, sway gracefully; many have grown more than 7 feet tall in this one growing season. Early morning dew transforms the seedheads into works of art. Silken strands of unseen spiders glow in the sunlight. Flocks of goldfinches munch on seeds, stocking up for winter, chirping their happy tunes, while shy sparrows occasionally pop up from the shadows, giving us a glimpse of their subtle beauty. Milkweed seeds blow gracefully in the wind.

The prairie truly must be walked to be appreciated. There is so much diversity, and so many stories to tell.

Touch a compass plant leaf on even the hottest day and it will be cool to the touch—with roots going down 14 feet, they pull up water that is chilled underground.

Monarchs live in symbiosis with milkweed plants (as do many other insects). Look closely and you may see a whole world on a milkweed plant.

Surprises can be anywhere—a hummingbird zipping by for a quick sip, a great blue heron flying overhead, drama as a hawk dives down to grab a vole. Fall on the prairie is colorful, alive, and a place of great wonder not to be missed.

Fall Migration

Fall migration is happening right now. Stop what you’re doing, grab a camera or binoculars, and go outside! You never know what you might see. It could be a fall warbler (but what kind?), a beautiful grebe, or a rusty blackbird—it may not even be a bird at all!

Spring and fall are times of great opportunity and diversity. With hundreds of species moving through, you get a chance to see and photograph some that would be impossible to find at any other time. Since they may be here only a few days before moving on, I like to get out any chance I get. 

Migration is not just for birds. Most know the mighty migration of the monarch butterfly, but did you know that some dragonflies migrate, too? You can often find large numbers of dragonflies hunting other insects almost anywhere in the Chicago Botanic Garden. The most common ones to find migrating are the darners (Anax sp.) and saddlebags (Tramea sp.).

When you spot a warbler, take a close look and listen closely to its song—birds within the species are notoriously difficult to identify. Also, keep your eyes open for warblers, kinglets, blackbirds, hawks, ducks, shorebirds, sandhill cranes, and more. There will be a steady stream of birds migrating through this area through November. Any place in the Garden can have birds. Listen for the sounds, watch for movement in the trees, and you may be lucky to see one of these beauties. Check the logbook at the Information Desk in the Visitor Center to see what other birders have seen and add your finds as well.

Damselflies 101

The Chicago Botanic Garden is a great place to find damselflies. You can find them in every location here, and different locations will often yield different species.

For example, you might find stream bluets along the river and orange bluets hanging out on the lily pads. Most species measure about an inch in length and can be easily overlooked, but when you take time to slow down and search for these tiny gems, you will be rewarded with finding some of nature’s most beautiful hunters. Indeed, these tiny insects are fierce hunters—but don’t worry, as they neither bite nor sting humans. Their preferred food choice is other, smaller insects (including mosquitoes).

The main differences between dragonflies and damselflies are their size and wing positions. Damselflies, in general, are smaller, and hold their wings over their abdomens. Dragonflies tend to be larger, with a heavier body, and hold their wings out to the side.

The most common species around here is the eastern forktail damselfly. Identifying them can be tricky, as they come in several different varieties! The males and females look very different from each other, and the females change color as they age.

I like to get out early in the morning. The light is low, there is often dew, and the insects move a bit more slowly until they warm up. One of my favorite places in the Garden to photograph damselflies is in the Dixon Prairie. They like to hang out on the grasses there. Walking slowly on the path next to the plants, you will see what look like tiny flying sticks. Damselflies will often congregate in one area and, if disturbed, sometimes land just a short distance away. I like to use my 105mm or 200mm macro lenses to photograph these beauties. They will fly until the first really hard frost. There are dozens of species native to this area—all of them beautiful and fierce hunters.

Bird Report

There was a nice assortment of birds at the Garden this morning!

White-crowned sparrows were the most abundant, and could be seen in almost every location. I saw a few warblers scattered about, but none in any large numbers. My best spot for finding birds was along the water in the woodland walk area of the Sensory Garden. I saw black-and-white warblers, Nashville warblers, ruby-crowned kinglets, gray catbirds, warbling vireos, palm warblers, flycatchers, and an ovenbird.

Southerly winds are expected for the next two days, which should bring in a LOT more birds. Now is the time to get out your binoculars and cameras and see some of these amazing birds for yourself! In a few short weeks they will be gone.

The miracle that is migration

After such a long, cold winter, I am especially looking forward to the gifts that migration brings.

Each day is a present just waiting to be opened. Here in Illinois, we can see more than 400 different bird species. Some are local residents, but most are just passing through. Starting in March and lasting through June, millions of birds will be heading north through Illinois to their breeding grounds.

First to move through are the ducks, then blackbirds, kinglets, shorebirds, herons, egrets, and finally the big show, warblers! If you don’t know what warblers are, I suggest you look them up; after you see your first one in the wild, you will be hooked. These tiny gems are a wonder to behold. I saw my first warbler of the year yesterday, a yellow-rumped warbler (one of the most common of the species). I’ve seen them hundreds of times, yet I was just as thrilled yesterday as I was the first time I saw one. I guess I’m hooked.

The Chicago Botanic Garden is a hot spot for migrant activity. With the advantage of water, woods, and prairie, it is an attractive spot for a large variety of birds. I’ve seen more than 200 species of birds at the Garden, and just this past week I was treated to migrating red-breasted mergansers, coots, and grebes. Plus, it was fun to see the resident birds returning from their winter in warmer climates, like grackles, red-winged blackbirds, and great blue herons. The goldfinches were also getting their breeding colors back after dulling down for the winter. Spring may be slow to get going this year, but the garden is full of colorful birds!

A fun way to spend the day is to grab a field guide, a pair of binoculars, or a camera, and see how many different species you can find and identify. There is even a ledger at the front desk to record your finds. If you need help, you can sign up for a bird walk and learn from an expert.

Migration is one of the greatest miracles on Earth, and is here for all of us to enjoy.
