Philadelphia Fleabane has been blooming all over the park in the past week. It's hard to miss, it looks like a small daisy on overdrive. What appears to be a single flower is actually a central disc of hundreds of tiny yellow blooms surrounded by more than 150

The bittersweet call and whistling flight of the Mourning Dove (Zenaida macroura) make it one of our most recognizable local birds. Females are slightly duller brownish-tan; males show a bluish-gray crown and somewhat stronger pink tones on the breast. There's a patch of iridescent feathers along

These plants belong to an ancient line spread across the Northern Hemisphere. Over millions of years, the line divided, resulting in related species in eastern North America and
A full slate of spring!

Crossing a footbridge at the park this week I saw a frenetic kerfuffle of water striders on the surface of the creek. My surprise at seeing them so early in the year sparked some research; here's what I found. Our creek water striders are in the Aquarius remigis
The poem of spring continues to unfold, with a stanza here and there reminding us just how cold winter was. Heard and seen, but not yet photographed - Tree Swallows! I've been working on project that incorporates iNaturalist observations in the Anson B. Nixon Park Project into a field

I'd like to begin hosting/leading more or less informal nature walks at the Nixon Park this spring. I am asking anyone who would like to participate to let me know their preference for day and time by completing this brief survey. Please feel free to share with
Names are the way we humans build relationship, not only with each other but with the living world... imagine what it would be like going through life not knowing the names of the plants and animals around you... scary and disorienting — like being lost in a foreign city where you
Snow from the late-January storm is still on the ground. For nearly three weeks nights have dipped into single digits, wind chills pushed well below zero, and daytime readings struggled to climb above freezing. It could be worse. As tough as February 2026 has been more than three feet
