Walking through the big woods this week, I felt like a kid in a candy shop. It was exciting to experience wonder after wonder. It is a time when winter seems to linger and spring has not arrived but there is more occurring than the senses can grasp.
Song Sparrows are active at brush piles along the forest edge and in wetland shrubs. Just a couple weeks ago, I was seeing a dozen species of birds daily and now it is two dozen. Sandhill Cranes announce evening, Canada Geese fly over, and Wood Ducks are swimming in Little Cedar Creek.
An American Woodcock flew in for its evening dance, saw me, and kept going. The next night a Great Horned Owl was hooting from forest edge and probably kept the woodcock from showing itself. A pair of Red-tailed Hawks soared over the Big Woods and power line clearing by day.
A Turkey Vulture on clean-up duty has been soaring over the highway by Ody Brook’s entrance looking for the dead opossum and muskrat that I reported killed on the road last week. The carcasses are not obvious among the roadside vegetation but the vulture can smell them at great distance.
Two Pileated Woodpeckers feasted at an old ash tree stump. My friend, Greg, was coming to visit and I told him about the woodpeckers at the driveway’s edge. He arrived, stopped, and watched as one woodpecker worked. When the woodpecker left, we looked to see what was being eaten. Termites.
On a smaller scale, Skunk Cabbages are blooming on the floodplain. They have a hood covering minute flowers. The hood protects this first flowering plant of the year from freeze damage. The hood wraps around an inner spike that holds many flowers. The spike with flowers is called a spadix and the hood is called a spathe. Small flies and crawling insects move into this temporary shelter where they find protection from being frozen. The plant generates heat that keeps the temperature above freezing in the spathe. Heat protects plant tissues and the variety of creatures in the hood. The benefit to the plant for providing lodging is that insects pick up pollen and carry it to other Skunk Cabbage flowers.
Other flowering plants already blooming at Ody Brook by mid March are Silver Maple trees, Speckled Alder, and Whitlow-grass. Whitlow-grass, a mustard, has a small rosette of leaves found on exposed bare ground. It is only about one inch across the radiating ring of leaves. Small white mustard flowers about the size of a pinhead ensure reproduction. The plant and its flowers are so small that few people notice them but hundreds are currently in bloom.
It is good to carry a small magnifying hand lens to examine the near microscopic world of life in wetland, field, shrubland, and forest.
Bluebirds still have not arrived to inspect nest boxes cleaned and readied. They arrive before wrens to claim bird houses. When wrens arrive, they enter and kill bluebirds or destroy eggs to use the box themselves. If houses are kept in open areas away from shrubbery and forest edge, it is less likely wrens will invade.
I place two bird houses within 15 feet of another. Tree Swallows often claim one and keep other swallows from nesting that close. The swallows do not mind having bluebirds as neighbors. The bluebirds, so to speak, have a swallow guard that protects them from other swallows that try to take the second nest box.
Nature niches have a greater variety and abundance of wondrous special treats than candy in a candy shop.
