Each year in the Twin Cities, humans and other wildlife patiently wait for spring. Some years it arrives to stay, others it arrives only to beat a fast retreat. But over the last few years, one of the few constants in this transitional period in the metro has been the presence of bald eagles. As spring creeps back they take to the sky, hunting for prey, fighting over territory, and mating.

A murder most fowl

As dusk approaches on a cold winter night, Twin Cities residents may notice an unusual number of crows flying overhead. Each winter, they show up by the thousands to roost in metro neighborhoods.

When people think about phenology, the study of natural phenomena and cycles, they usually look up. We tend to focus on events like bud break, bird migration, leaf fall, etc. But what about the changes going on beneath our feet? Looking down once in a while may help you familiarize yourself with the buzz of activity underfoot, including the effects of one particularly damaging invasive species: earthworms.

Mini-mystery revealed: They're caterpillar houses.

The bagworm caterpillar is safe when left in its tiny house.

The vulnerable bagworm caterpillar is safe from most predators inside the case it built around itself. Only its head and forelegs extend as it moves about, then readily retreat if danger threatens. 

The little known, but very abundant, bagworm moth has recently emerged from the protection of the home it built and carried on its back throughout its larval-hood!
