Sycamore Grove Farm, Madison County

Some of my favorite birds to see (and hear) are ravens and their “cousins” the fish and common crow. The morning of 1/29/23, I was treated to a small flock of eleven fish crows flying along our farm’s southern border. Fish crows can be mistaken for the common crow – until you hear their call. It’s a nasal version of the crow call and once you hear it, you will always know which crow you’re seeing. 

And wait until you see the “big boy” of the group: the Common Raven. It’s a special treat to have this species visit our farm, which it does every several weeks or so. But our crow population is very territorial. If they spot a raven, they tend to hassle their larger “cousin” until it leaves the area.

Sycamore Grove Farm, Madison County

I have always been an “outside” person – playing outside until my mother made me come in when it got dark. One of the favorite things about being outside was the birds! I grew up in Central California (way before the area where we farmed was called Silicon Valley).  I became really focused on learning how to identify birds while completing my Bachelors in Biology in Illinois. Excited to share my new-found “expertise” with my family, you can imagine my chagrin when I found out that many of the birds that I observed in the Midwest didn’t live in California. The Rocky Mountains are a formidable natural barrier. Some bird guides (notably Sibley Guides) are specific to birds east of or west of this mountain range.

Fast-forward fifty years: my husband and I have a 25-acre farm in Central Virginia that we named Sycamore Grove Farm for all the beautiful sycamores that grow along our borders. The majority of our land is a hay field, which attracts a lot of different kinds of birds: hawks, crows, and blue jays are numerous. We see eastern meadowlarks throughout the year. Three sides of the farm are 50-foot tall cedar trees that rooted from old cedar fence posts. These trees attract cedar waxwings and robins who feast on their berries. We also have a wonderful variety of woodpeckers including the Hairy and Downy woodies, red-bellied and red-headed woodpeckers, northern flickers and several pileated woodpeckers whose silhouette  definitely show that birds are the only surviving dinosaurs. Check out a fascinating animated video “Why are birds the only surviving dinosaurs?” on the  Natural History Museum website.  This museum is based in South Kensington, London and Tring, Hertfordshire in the United Kingdom.

I bird every morning and report my observations on The Cornell Laboratory or Ornithology’s eBird site. Their website (https://ebird.org/home) offers great information on everything about birding: how to identify birds, finding “hotspots” near you (it’s an honor to be listed among my county’s “Top Birders”), and seeing what birds to expect throughout the year in any region or location.

​I plan to share some of my special birding experiences in this blog. And I invite you to jump in and share your experiences as well. Birders always love to hear stories about that special sighting – so please join me with your stories and I hope you enjoy mine.

Happy birding!

I enjoy the surprise of blooms in my garden each year and always add new native species. Last fall, I received two eastern prickly pears (Opuntia humifusa) from a fellow gardener. I planted both cacti in a “problem” area of my garden. The area is shaded, gritty, stays dry and reminds me of a mini “Sahara.” In the past, anything planted there had shriveled and died. I hadn’t realized that Virginia had a native cactus and wasn’t sure if it would endure Virginia’s winter.  The addition of the spiny plant led to many other discoveries.

While taking a walk in July, I noticed a greenish-yellow round bud on the top of my eastern prickly pear.  I watched in anticipation, waiting for that ultimate burst of color.  I had seen patches of eastern prickly pears at Blandy Experimental Farm, the State Arboretum of Virginia, but had never seen one in bloom.  I was not disappointed when the bud burst open to display a bright yellow flower with seven sepals, one pistil, seven or more petals, and many stamens.  The center was an orange hue, and the petals were heart-shaped with a single point on each end.  I had no idea that the cactus bloom would be so radiant and beautiful.  I was interested in learning more about the plant and began to research. 
   
For months there was no growth. I can only guess that it was establishing its root system.  Winter came and my cacti retreated, turning wrinkly and slightly yellowed.  I continued to worry that it would not survive the harsh winter temperatures and the snow. But in spring, it came back to life and was once again bluish-green with a matted waxy sheen.  It grew taller and added new sessile pads; it now has six.  The pads have air pores called areoles that are arranged in a diagonal row pattern.  Each areole has a small tuft of sharp bristles called glochids that develops a sharp spine.  The thorns are deciduous, help to shade the cactus's flesh, and help the cactus retain water. 
 
In discovering more about the plant, I found that the eastern prickly pear is in the Cactaceae family.  The genus name, Opuntia, is pronounced ō-pun′shi-a.  The origin of the term Opuntia was coined by Pliny (AD 23-79) and it is thought that the name refers to the Greek town of Opus, where a cactus-like plant grew.  Humifusa is derived from a fusion of the Greek words “humus” meaning soil or earth and the word “fusus” meaning to spread.  To remember the Latin name Opuntia, I visualize the pad of the cactus rounded like the O with spines.

The cacti can grow up to two feet tall.  The flowers can grow to be 2 to 3 inches wide and bloom from May to July.  The flower is a golden yellow with a bright orange center.  After the bloom is spent, it is replaced by an edible fruit full of seeds. The fruits are called cactus figs or tunas.

The prickly pear genus originated in South America.  The fruit is often eaten by small mammals that help to disperse the seed.  The seeds were carried in the gut of small and large animals when the land was bridged between the northern and southern continents around three million years ago.  The animals that spread the seed in their dung include deer, squirrel, rabbit, skunk, coyote, fox, turkey, and turtle.

Pollinators are attracted to the plant, particularly native bees.  Both long-tongued and short-tongued bees visit the flowers, including bumblebees, the large carpenter bee (Xylocopa virginica), digger bees (Melissodes spp.), leaf-cutting bees (Megachile spp.), halictid bees (including green metallic bees), and plasterer bees (Colletes spp.). Long-tongued bees suck nectar or collect pollen, while short-tongued bees collect pollen only; the larger bees are more likely to cause cross-pollination. 

An amazing adaptation of the eastern prickly pear was noted by Charles Darwin. He recognized that the cacti have thigmotactic anthers that curl over and deposit their pollen when touched. This movement can be seen by gently poking the anthers of an open Opuntia flower.  I recommend watching the video at https://awkwardbotany.com/tag/opuntia/.  The sensory movement is fantastical and unexpected.

Historical literature shows that the plant was used in many ways.  There are recipes for jellies, pickled cacti, candies, drinks and more. The fruit’s taste is reminiscent of watermelon and the plant is rich in Vitamin C and antioxidants that are an excellent source of energy for humans and wildlife.   A practical use for the plant includes the use of the spines as needles for sewing.  In Latin America, small insects that infest the plant  were collected to make a bright red dye.  Currently, the medicinal uses of the plant are under investigation.  The research includes the uses of the plant in treating type 2 diabetes, obesity, high cholesterol, alcohol hangovers, colitis, diarrhea, benign prostatic hypertrophy, and viral infections.  Prickly pear cactus contains fiber and pectin which can lower blood glucose by decreasing the absorption of sugar in the stomach and intestine. 
 
The “prickly” has proven to be a favorite in my native garden as it is a treasure of ever-unfolding uses and beauty.
