Dr. Caroline Judy will present a program on June 22 on her work studying an unusual case of island speciation seen in Jamaican streamertail hummingbirds (Trochilus spp). Streamertail hummingbirds are closely-related hummingbirds that are distinguished on the basis of bill color, which is bright red in the Red-billed Streamertail and jet black in the Black-billed Streamertail. Historically, they have been treated as subspecies by the North American Classification and Nomenclature Committee. However, Dr. Judy found evidence for reproductive isolation that informed the committee’s recent decision to elevate streamertail hummingbirds to full species status. Dr. Judy also will discuss many aspects of streamertail biology that are common to all hummingbirds, and focus on the ultimate question – why are hummingbirds as a genus so rich in species?

Dr. Caroline Judy is a research associate in the Division of Birds, Smithsonian National Museum of Natural History. Caroline is interested in how and why birds form new species.

Cost: Free

Registration is REQUIRED.

Dragonflies and damselflies are some of the most mysterious and beautiful animals that live at the Clifton Institute, and June is the perfect time to search for them. This workshop will cover the basics of dragonfly identification and biology. Participants will then practice what they have learned by visiting lakes, streams, and fish-free vernal pools, each of which host distinct dragonfly communities. You are welcome to bring a lunch and eat on the picnic tables after the program.

Warrenton, Virginia 20187

Join this visit to an active Bobolink nesting colony in partnership with the friends at Virginia Working Landscapes! Bobolinks are unique and beautiful birds that select hay fields for nesting. Sadly, they are declining as a result of nest losses from cutting the hay early in the summer. Participants should enjoy views of adults and fledglings and hear their wonderful song that is reminiscent of R2-D2. The private property we will visit still hosts these wonderful birds because the owners delay haying until the Bobolinks have finished nesting. You should also see a variety of other breeding birds such as Purple Martins, Grasshopper Sparrows, Eastern Meadowlarks, and Blue Grosbeaks.

Plant Family Identification Workshop, June 10th

Warrenton, Virginia 20187

If you’re learning to identify plants, learning the common families can really help narrow down your options when you’re faced with an unfamiliar specimen. If you already know a few plants, learning their families can provide a useful framework to help organize all the species rattling around in your brain. Whatever level you’re at, learning to identify the plant families around us is a really fun way to get to know the natural world. In this program, Managing Director Eleanor Harris will give a brief talk on the ways to identify the most common plant families in Virginia. Then she will lead a short walk in the fields to practice your plant family identification skills!

Who doesn’t love fireflies? Many of us have fond memories of catching fireflies or watching a magical light show on a summer evening. But why do fireflies flash? What do they eat? How many species are there? And are fireflies disappearing? Learn all about these fascinating insects with Ariel Firebaugh, firefly researcher and Director of Scientific Engagement at UVA’s Blandy Experimental Farm (Boyce, VA). After a short talk, participants will walk around grounds, practice identification, and enjoy the light show!

FMN CE Event Recap: Wandering through the Wildflowers at Riverbend Park with Alonso Abugattas

On April 23, 2023, Fairfax Master Naturalists spent a cool, sunny Sunday hiking with native plant expert Alonso Abugattas to learn more about native and invasive wildflowers. FMN members in attendance learned to identify many native plants such as Canada Waterleaf, Star Chickweed, Wild Blue Phlox, Smooth Solomon’s Seal, False Solomon’s Seal, Spring Beauty, Ramps/Wild Leeks, Sweet Cicely, Virginia Bluebells, Blue and Cream Violets, Clustered Snakeroot, Sessile Trillium, and Kidney Leafed Buttercup. Non-natives included Gill over the Ground, Garlic Mustard, Bulbous Buttercup and Star of Bethlehem. Participants also heard stories about the folklore and uses of a variety of wildflowers. One example, the Spring Beauty plant is also known as fairy spuds for its small potato-like edible roots. See photos below for more.

Cost: Free

Registration is REQUIRED.

Warrenton, Virginia 20187

In 2022, a research project was started to study what habitats Box Turtles use at different times of year so that participants and other landowners can know what the best time of year is to mow fields and do other land management practices that might disrupt or even kill Box Turtles. On this second installment of Science Saturdays, participants will help get the 2023 season started by looking for turtles that were radio-tagged last year and potentially finding new turtles to tag. This is a special opportunity to tag along with our staff researchers and see how field science is done.
