Learn more in our Field Guide to November.

Here’s your field guide to some moments that you might not otherwise notice during these few precious weeks that feature colored hills beneath a deep blue sky.

Field Guide to September 2024

It can happen almost anywhere. On a cool, foggy morning, for example, when fall warblers drop from their nocturnal, migratory flights into your backyard, and clusters of Common Green Darners congregate on a nearby riverbank. Or along a mudflat some afternoon when you notice a Spotted Sandpiper teetering and then darting after prey. Or on some wooded trail when you spot the first ruby red leaves among late-summer's faded green. Here is your field guide to life slowing down and on the move in September.

Here's a guide to some of the splendor.

Enjoy this guide to some of the month's delights as the dream of June comes true.

If you're lucky, you may even catch the buzz of an early-season bee as it forages. Here’s our guide to some of the new life bursting forth this month.

Field Guide to March 2024

On Tuesday, March 19, at 11:06 PM, spring will arrive in Vermont. The spring equinox marks the moment the sun crosses the celestial equator—an imaginary line in the sky above Earth’s equator—from south to north. On the day of the equinox, people worldwide can see the sun rise due east and set due west. While the sun may be predictable, March weather is not. In fact, March is appropriately named for the Roman god of war, Mars. March is a month of battles between warm and cold, between winter’s refusal to leave and spring’s insistence on arriving. So, here are some signs of spring to look out for this month.

Field Guide to April 2023

In April, the northern forest is laid bare with cold desire. Our long-dormant senses awaken. The sweet smell of soil rises to our noses, carried by the ultralight spores of Streptomyces bacteria launched into the air by the impact of raindrops. Our ears cock skyward at dusk as a Woodcock chatters and twitters above. Spring Peepers burst forth in the evening, with up to 4,000 peeps an hour. Blades of wild leeks slice through autumn's soggy, brown remains to release sweet-onion perfume. Bright white Hepatica opens for wild bees and provides a feast for our eyes.
