Unpredictable weather, fuzzy eaglets and great horned owls

This time of transition between winter and spring can be a wishy-washy, ambivalent affair. It’s sunny and 50 degrees, then 20 and snowing. Likewise, some bald eagles are still hanging out in their winter homes or migrating along the Mississippi River, while others are nest-bound, feeding fuzzy eaglets. Another impressive hunter, the great horned owl, is also nesting these days. Luckily, there's great local spots to see all of this avian action, both outside along the Mississippi River and online.

The green amidst the gray: the distinctive phenology of non-native shrubs

It’s finally (or already!) November and the leaves have fallen from the trees. Well, not quite all of them.

Is it goldenrod or ragweed?

Many people suffer from allergies during mid to late summer, but few know exactly what causes them. Folks usually chalk these allergies up to hay fever, and rightly so, but are all plants to blame? Goldenrod, a prolific flowering plant with masses of golden flowers, is often mistakenly blamed for causing the itchy eyes, runny nose and other symptoms that many of us suffer from. However, for most of us, ragweed is the true culprit.
