Phenology

Once on the brink of extinction in Minnesota and beyond, wild turkeys are now a common sight for Twin Cities and greater Minnesota residents alike. This November, take a minute to learn about this wild animal with an interesting history. >>

Each year, the cool fall weather is accompanied by a flurry of wildlife activity. Most species are busy preparing for the winter — gathering and storing food, prepping their nests and burrows, and putting on a few extra pounds. In the Twin Cities, no animal is a better example of this than the gray squirrel.

While many residents consider them a bit of a nuisance — chattering from the trees, darting across streets, and leaving piles of chewed food on decks and sidewalks — these smart little critters have an interesting history and impressive adaptations that allow them to flourish in our human-dominated landscape. >>

Each fall, two common invasive plants produce starkly colored berries: European buckthorn bears shiny jet-black fruit while bush honeysuckle produces brilliant red to yellow berries. Unfortunately, birds that dine on the fruit not only spread the invasives' seed but are negatively impacted by the berries themselves — they can even disrupt some birds' mating patterns! >>

The aptly named hummingbird moth or clearwing moth is not uncommon, but with its beautiful colors and wing patterns, it's a delight to see one hovering over flowers seeking nectar.

Of the 18,000 species of ants, bees and wasps in North America, the pelecinid wasp is among the most interesting. This insect is so unusual it shares its family (Pelecinidae) with just three other species in the world, with no others in North America. But don't worry, that 'stinger' isn't what it looks like.

This surprise visitor to the Robert Street lift bridge is commonly found in trout streams and is considered an indicator of good water quality.

Found on sumac, these beetles have an especially interesting way of protecting their young.

Fans of The Lord of the Rings will recognize this query of Gollum, the odd underworld creature, as he pondered the riddle of Bilbo’s pocket contents. The star character of this month’s Nature Notes is also a creature of the underworld, seldom seen above ground. And like Gollum, these animals have a lead role in the world they inhabit.

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.

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. While the gatherings may seem ominous to some, they serve an important purpose for these intelligent birds.
