In bloom in our front garden now: Virginia Spiderwort, Tradescantia virginiana. Never mind the slightly spooky name, this is a great native plant if you love pollinators (check out the bumblebee and the Solitary Sweat Bee enjoying spiderwort snacks). Another huge bonus? Deer do not like it!

Red foxes like this gangly cub “greatly enhance the ecosystems they inhabit. As highly mobile animals, red foxes act as dispersal agents for many plants. They can also regulate populations of rodents, which aids in the reduction of Lyme disease within the landscape.” -Rutgers NJ Agricultural Experiment Station, ‘Red Fox Ecology and Behavior’

From a New York Times bestselling nature writer comes a celebration of what goes on outside in the dark, from blooming moon gardens to nocturnal salamanders, from glowing foxfire and synchronous fireflies that blink in unison like an orchestra of light. We can't wait to discuss this incredible story with you.

Team Birdin’ With Glorious Purpose would like to thank everyone who cheered us on, made donations, fed us snacks, and drove us all over Essex County during Saturday’s World Series of Birding. Despite the rainy weather, we all had fun finding a wide variety of birds in multiple locations. Over the course of the day we were able to identify 112 species, and tied for 4th place in our division.
112 species is a lot of birds in a densely populated county, and all of them are deserving of conservation. Your support of our work on the Global Big Day of birding, and every day, makes a difference in the lives of wild birds. Thank you! 🪶
Thank you, Turtle Back Zoo! We just picked up 34 more species on the reservoir!
