Sagawau is waaaaaay out in Lemont, so pretty far from me, and it's also bit confusing to find when…read moreyou get there. But I really enjoyed it so I'd say it's worth it, and now I'll know where I'm going in future! Word to the wise: There's the large parking lot, and what looks like a driveway is not. Park in the lot and use the wide paved path to get to the nature center.
The purpose of the first preserve system was to both preserve and conserve, but also to provide natural areas in which people could recreate. They also have a nature center here with exhibits, as well as a variety of programming. I came for a program. A land acknowledgement was provided to connect the land to its history, and the people who once called this land home.
I came for a hummingbird program, which took place in the hummingbird garden. The garden had quite a few bees and some wasps, but those insects are actually invasive in this area so you may see traps out for them so they don't take over the hummingbird garden. There are hummingbird feeders around to bring the hummers out. But nectar isn't their only source of food; they'll eat insects and invertebrates. Most importantly, they need pesticide-free habitats to survive. It was interesting to learn that hummingbirds live only in North, Central, and South America. When colonizers came into contact with hummingbirds, they thought they had no feet and that is where their scientific name is derived.
Hummingbirds are surprisingly loud! The ruby-throated hummingbird is only ruby throated for the males. Juveniles and females have a white throat. But the color only comes out with the light, as it's iridescent, so the males may look black. Ruby throated is the only native one in Illinois. The juveniles are about the weight of a penny. In migratory season, they try to double their weight in order to sustain their migratory most fly over the Gulf of Mexico, which is a single flight of about 600 miles. They can do that flight in 16-24 hours. Hummingbirds fly with a figure eight pattern, which allows them to be one of the few birds that can fly backwards. It also allows them to hover! Migration is hard, so why do they do it? At least in part, it's because there's less competition. Apparently day length is a trigger to let birds know when to begin migrating, and the plants and flower on which they rely for food usually coincides to their migratory season.
The nesting behavior of hummingbirds draws a direct line between environmental stewardship and habitat protection. They line the nest's outside with lichen and plant scale, and line them inside with soft things like dandelion fronds. Air pollution won't affect the hummingbird directly, but it will affect lichen and thus the integrity of their nest and subsequently their success in breeding. They will use spider webbing to bind their nest, which makes spider conservation important too. How fascinating how these things all connect!
Whilst visiting Sagawau, I learned that this preserve is a licensed bird banding station--not just for hummingbirds. Banding allows us to gather much of the information that we have about birds in general. The information gleaned from banded birds can tell us about their migratory patterns, lifespan, and so on. I believe they have some events during the year where you can observe this process.
In addition to their great programs, they have a nature center with exhibits related to the natural history of Sagawau and the region. One of the things that makes Sagawau so unique is it is a dolomite prairie, of which only about 500 acres exist in the world--over 100 of those acres being here. There are several trails to walk, and they have maps showing these to help guide your way. And this site turns into a cross-country ski location in the winter! In that season, walking is not permitted on the trails because they're used for skiers. They have lessons and equipment rental, but you can also bring your own gear--you just need to call first to make sure it's open for skiing, dependent upon the snowfall.
I saw more open acknowledgment of snakes here than at some of the other preserves, which may make me nervous to visit very soon--snakes in just about any capacity (cartoon, real, image, etc.) creep me out more than anything. But, Negin is the employee that led the hummingbird chat, and she was really great. Welcoming, inclusive, knowledgeable, and friendly. I'd love to attend more of her programs.
