Planting for the Picky Eaters

Many insects are picky eaters, only able to eat the plants with which they evolved, meaning the plants that are native to their region. Butterflies are a good example, since although the adults can sip nectar from non-native flowers, their caterpillars depend on specific native plants.The majority of bees are more flexible than that, able to eat the pollen and nectar from a variety of species. They are known as generalist species, although even in their case they have their own favorites. The European Honeybee, for instance, is a generalist but chooses certain flowers in preference to others.

Of the approximately 400 native bee species in Virginia, about a fifth are plant specialists. Examples include the Spring Beauty Bee and the Blueberry Bee, which (unsurprisingly) depend on the flowers of Spring Beauties and Blueberries. These bees are short lived as adults, emerging when the plants they depend upon are in bloom, and quickly gathering the pollen they need to store in their nests for their larvae, thus pollinating the plants while they are at it.

Our local ecosystem requires the full spectrum of plant/animal interactions to flourish. It is easily knocked out of balance when too many native plants are displaced by introduced species, something that has happened in many of our yards. We can restore that balance by planting a lot of native plants. One strategy could be to start with flowers that feed various specialist bees from early spring to late fall, because they will also supply food for the generalist bees. Since many of these flowers attract butterflies and hummingbirds as well, they make a winning combination. A list of popular native garden plants that feed specialist bees can be found on the Plant NOVA Natives website. It feels good to help the bees, whose numbers are in decline.

One of the many charms of native bee species is that they are highly unlikely to sting you, assuming you don’t try to grab one or otherwise threaten it. While they are foraging on a flower, you can get your face (and your camera) right up to them, and they will almost certainly ignore you. Gazing at bees brings surprises, as they come in many sizes and colors, including metallic blues and greens. It is particularly mesmerizing to watch bees on plants such as White Turtlehead, where they pry open the flowers and crawl inside, then back themselves out again, butt first. You can get a peek at those and other cute native bees on this two minute video, filmed in Fairfax County.

Plant NOVA Trees Event Volunteers Needed

Plant NOVA Natives was launched in 2014 to promote and increase the use of locally native plants in Northern Virginia. One of nine campaigns within the state-wide Plant Virginia Natives marketing partnership, it is a grand coalition of governmental, nonprofit and for-profit organizations that have pooled their resources to work toward this common goal. The campaign’s success rests on the action of the millions of individuals who make up our Northern Virginia community.

Plant NOVA Trees is a new and focused drive by the Plant NOVA Natives campaign to significantly increase and preserve the native tree canopy in Northern Virginia. The drive will launch in September 2021 and continue through the fall of 2026.

They are looking for people who can organize some kind of tree-related public event sometime this fall. To launch the native tree campaign, they will be sponsoring a region-wide Celebration of Trees, September through November. They are hoping that numerous people in every county will help them create buzz.

Some ideas for events include:

Tree walks (For the general public, you would want to make it short, snappy and fun.)
Tree plantings (be sure to report them on My Tree Counts)
Removing invasives that threaten trees
Webinars
Labelling trees with their names or placing signs in front of trees describing their particular benefits to wildlife and humans
Creating a GPS map of your community’s trees
Collecting seeds from your trees to be sent to the state nursery that grows seedlings
Forest bathing, scavenger hunts
Tie yellow ribbons around old oak trees (and red ones around red maples, etc)
Geocaching
Fairy houses in the woods
Photo contests
Anything creative you can come up with!

They have a sign to mail to organizers as well as brochures, and where selling their Native Plants for Northern Virginia guides is an option, they can provide those. If you do put on an event, they would love to add it to their Celebration of Trees event calendar, so please let Margaret Fisher know at [email protected].

The Fairfax Chapter recognizes the valuable work to be done by Plant NOVA Trees and recently donated $2,500 to the campaign. Funds will be used for promoting awareness of the program and for community tree identification projects. You may make your own donation here.

ACTION ALERT: Help Prevent the Possible Spread of Avian Disease

Clean and take down your feeders and bird baths until further notice!

As hard as it is for bird watchers to take their feeders down, there is now a critical reason to do so. Recent unexplained bird deaths in our region prompted organizations such as the U.S. Geological Survey and the Virginia Department of Wildlife Resources to recommend that citizens remove their feeders and bird baths until the cause of the mortality is determined.

If you do find a sick or dead bird, please report it to the VA Department of Wildlife Resources here.

For more specific information about avian deaths and how to possibly prevent them, read below.

From U.S. Geological Survey
Release Date: JUNE 9, 2021

In late May, wildlife managers in Washington D.C., Virginia, Maryland and West Virginia began receiving reports of sick and dying birds with eye swelling and crusty discharge, as well as neurological signs. No definitive cause of death is identified at this time.

This bird (pictured above) was found in the Washington, D.C. metro region with swollen eyes and crusty discharge, a sign observed on most birds affected by a May/June 2021 mortality event in the area.

The District of Columbia Department of Energy and Environment, Maryland Department of Natural Resources, West Virginia Division of Natural Resources, Virginia Department of Wildlife Resources and National Park Service are continuing to work with diagnostic laboratories to investigate the cause of mortality. Those laboratories include the USGS National Wildlife Health Center, the University of Georgia Southeastern Cooperative Wildlife Disease Study and the University of Pennsylvania Wildlife Futures Program.

Birds congregating at feeders and baths can transmit disease to one another. Therefore, the state and District agencies recommend that the public in the outbreak area:

Cease feeding birds until this wildlife mortality event has concluded;
Clean feeders and bird baths with a 10% bleach solution;
Avoid handling birds, but wear disposable gloves if handling is necessary; and
Keep pets away from sick or dead birds as a standard precaution.
If you encounter sick or dead birds, please contact your state or District wildlife conservation agency. If you must remove dead birds, place them in a sealable plastic bag to dispose with household trash. Additional information will be shared as diagnostic results are received.

FMN CE Hike: Bluebird Box Monitoring — Awesome!

BB nest feature photo by Barbara J. Saffir

Have you ever wondered what’s inside those white boxes on poles standing in open fields? They are Bluebird boxes paid for and erected by Bluebird Societies to provide habitat for Bluebirds, native cavity nesters. Trained personnel regularly monitor the boxes to record data for scientific research. A Fairfax Master Naturalist group recently explored the inside of 12 of them with Larry Meade, Northern Virginia Bird Club President and volunteer with the Virginia Bluebird Society. I was reminded of the carol The 12 Days of Christmas as Larry carefully opened each “gift” for a peek inside.

Organized by FMN Barbara Saffir, we met at Clark’s Crossing in Vienna on the Washington & Old Dominion Trail. Larry tapped the side of each box first to warn the parent bird of our approach. Their departure from the box was our first clue to which species was inside. The boxes are intended for use by Eastern Bluebirds but the conservation groups don’t mind if they are used by Tree Swallows (TS), Chickadees and other native cavity nesters. Nesting by other species, such as the non-native House Sparrow, is prevented by removing nesting material before it is completed. The opening is too small to allow entry by European Starlings.

Larry then unscrewed the side of the box, lowered it and we’d look inside. What follows is the day’s official report, enhanced by Larry’s astute birding observations and comedic interludes:

TS nest by Julie Ables

Nest 1 – TS nest – 5 eggs
Tidbit: Tree Swallows use feathers to “feather their nests.”

Nest 2 – BB nest – 3 eggs
Tidbits: Bluebirds use pine needles to make their nests. Larry was logging eBird sightings and “birding by ear.” He wryly noted “butterflying by ear” doesn’t work.

Nest 3 – TS nest – 4 babies ready to go
Tidbit: We viewed quickly so parents could return and resume feeding these voracious eaters.

Nest 4 – BB nest – 3 babies
Tidbit: Larry used a mirror so we could see the babies tucked deep in the nest. This is the second brood in this box for the Bluebird pair.

Nest 5 – TS – 4 babies

Nest 6 – TS nest – 5 eggs
Tidbit: Parent was agitated and circling us. We moved on quickly.

Nest 7 – TS nest -4 big babies
Tidbit: Box monitors remove a nest after the babies have fledged so parents can build a new one. Turkey Vultures are known as TVs. What is a pair called? A TV set.

Nest 8 – TS nest – 5 babies

Carolina Chickadees by Marilyn Parks

Nest 9 – Chic nest – 3 Babies
Tidbit:  Carolina Chickadees! Parents use moss to make the nest. Chickadees are native species and left alone.

Nest 10 – empty
Tidbit: In nearby trees we see a juvenile Orchard Oriole! Larry notes that seeing a new bird is like seeing a movie star.  So true!

Nest 11 – TS nest – 3 babies
Tidbit: We discover a nearby mulberry tree and taste some of the berries. No wonder birds love them!

Nest 13 – BB nest – 5 eggs
Tidbit: The nest is about 3 times as high as the other BB nests we’ve seen.

If you are interested in volunteering to monitor bluebird boxes, contact the Virginia Bluebird Society. Monitoring season runs from the end of April to early August each year. The excitement and joy of opening the boxes will enhance your contributions to citizen science!

Cicadas! Cicadas Everywhere!

Article and photo by FMN Ana Leilani Ka’ahanui, also of Capital Nature

What’s that late spring, early summer buzz, that loud chorus in the trees, all over the DC metro area? The 17-year periodical cicadas have made their entrance, to the fascination and delight of nature lovers in our region. While some may fear the emergence of a billion insects, many are reveling in this natural wonder, as evidenced by the explosion of cicada photos on social media. There’s even a phone app for reporting sightings. Cicada Safari will record and track your discoveries on a live map, and help scientists collect valuable data.

Want to learn what the fuss is all about? Visit Cicada Mania for everything you need to know about the 3 periodical species of Brood X: Magicicada septendecim, Magicicada cassini and Magicicada septendecula. And great radio programming by WAMU’s environmental reporter Jacob Fenston. While most cicadas have red eyes, did you know that some have white, gray, blue, or multi-colored eyes? Learn more fun facts like this by playing Brood X Bingo.

As the ground is now well above 64 degrees, Brood X is emerging to climb trees and plants to molt, then head to the treetops for some raucous partying to mate. Females lay their eggs in trees and the nymphs will later drop onto the ground, where they will burrow down and live till the next emergence party in 17 years. Their life cycle is a short 5-6 weeks and has been documented in this Return of the Cicadas video.

Dr. Michael Rapp is an entomologist at the University of MD and an excellent local authority on cicadas. Check out his media appearances at The Bug Guy. The New York Times covered all things cicada in great detail in this article. USDA entomologist Dr. Sammy Ramsey explains the science behind their loud calls. If you’re feeling adventurous, here’s a Washington Post article about recipes for cooking them.

Cicadas can be artists too. During the recent global City Nature Challenge, Teresa Leonardo discovered that cicadas had burrowed tunnels under some tarps in her yard in West Falls Church, VA in their effort to emerge. See their intricate patterns on iNaturalist.

According to the National Wildlife Federation: “Cicadas are mostly beneficial. They prune mature trees, aerate the soil, and once they die, their bodies serve as an important source of nitrogen for growing trees. When cicadas come out, they’re eaten by just about anything with an insectivorous diet.” As nature’s grand buffet, these curious creatures are providing entertainment and education for all ages.

City Nature Challenge: the results are in!

Article by FMN Ana Leilani Ka’ahanui & Stella Tarnay, both of Capital Nature

Nature nerds celebrate! The results are in for the global City Nature Challenge and our region rose to the occasion again. Out of 419 cities in 44 countries, the DC Metro Area ranked:

• 2nd for observers: 2,002
• 2nd for observations: 43,295
• 8th for species: 2,977

How did Fairfax County do? 11,916 iNaturalist observations of 1,610 species were made by 488 observers. There were 588 people that lent their expertise to make identifications. These results were an improvement over 2020 where 7,750 observations were made of 1,249 species by 391 observers. There were 10 more identifiers last year at 598. See the top ten species identified in Fairfax this year.

Capital Nature along with dozens of area partner organizations hosted over 30 virtual and in-person trainings and events, culminating in a virtual ID Party and a Celebration. Participants shared their favorite discoveries including unexpected flower sightings, five distinct sightings of hog-nosed snakes, a persnickety groundhog and alien-like eggs of a Spiny Assassin Bug. We’re pleased to say that the native mayapple topped the list as the no. 1 species observation, leaving the invasive garlic mustard far behind. For details on all the species that were discovered, visit the project on iNaturalist.
