BRANCHING OUT The Buzz on Hummingbirds – Summer Breeders and Voracious Feeders By Susan Sims

Summer is here! The sun is bright; lush vegetation abounds; and one of the smallest birds is ready to start a family. The Ruby-throated Hummingbird (Archilochus colubris) is the only hummingbird commonly found in eastern North America, where it summers for the breeding season. It’s easy to spot the bejeweled beauty zipping through the air, humming along, flitting from flower to flower in preparation for breeding. The energetic birds migrate from Mexico and Central America to North America in spring, completing a 20-hour trek across the Gulf of Mexico. They are iridescent emerald green, and the males are distinguished by their red jeweled throat patches, or gorgets. At a mere 3 grams, the bird is tiny to say the least, yet it certainly packs a wallop in terms of ability and traits. Hummingbirds are unique among avian species because of their tremendous flight adaptations.

Their wings beat up to 70 beats a second – more than any other bird. They can fly forward, backward and hover in one spot with precision, putting other birds and even machines to shame. In fact, their ability to hover was proven to be more efficient than mini-helicopter drones by 20 percent. But their amazing physical adaptations don’t end there. Muscles make up 30 percent of their body weight, akin to an average sized man having 60 pounds of pure muscle. If that’s not impressive, then check out the hummingbird’s extreme cardiovascular abilities. Their resting heart rate is 225 beats a minute, which increases to over 1,200 beats a minute in flight. To support this rapid metabolism, the birds will consume two times their body weight in food daily. Continued on page 2

Walker Nature Center 11450 Glade Drive, Reston, VA 20191 Enjoy year-round access to trails, free parking and restroom facilities dawn to dusk.

Ruby-throated Hummingbirds enjoy nectar from long, tubed flowers and are partial to red, orange and purple blossoms. They also snatch insects out of the air and munch on the occasional spider. Their bold nature and attraction to certain flowers makes them a common visitor to garden habitats, if the right plants are present.

FEATURES

72 acres of forested land, a picnic pavilion, demonstration gardens, educational signage, a campfire ring, two streams, a pond, the entrance to 44-acre Lake Audubon and an interpretive green building, known as Nature House.

Want to attract more hummingbirds to the garden or backyard?

Choose an assortment of flowers and plants with overlapping blooming times that provide a summer full of delicious nectar. Good plants for these birds include Bee Balm, Blazing Star, Cardinal Flower, Jewelweed, Penstemon and Trumpet Creeper. The native versions of these plants are preferred, as cultivars often produce less nectar than wild native lineages. Supplying sugar water in a feeder is acceptable, but care must be paid to keep it clean to prevent fermentation and illness in the birds. Adding a mister or small bird bath will provide water. Small shrubs will give shelter, and soon, hummingbirds will be stopping by for treats. But don’t be surprised if you see them chasing one another off. They are solitary animals that usually only come together for breeding purposes. As summer progresses, the males will find mates, then continue on their way to prepare for fall migration. The female will rear the infants on her own. She’ll build a walnut-sized nest, supported by simple spider silk and lined with soft fibers. She’ll lay two eggs the size of peas, and from these eggs will hatch feisty little birds ready to take on the world in one short month. They’ll fill up on nectar and insects to increase their body weight by 40 percent before heading south in the fall.

Groups: Please call ahead to arrange your visit. Branching Out is a quarterly publication of the Walker Nature Center (WNC), owned and operated by Reston Association. The mission of the WNC is to foster an environmental stewardship ethic in the community. It is named after Reston’s first Open Space and Nature Center Director, Vernon J. Walker.

Creating a hummingbird habitat can provide hours of observational joy as well an important breeding area for our smallest birds. These vivacious beauties are known to return to the same areas year after year, even to the very same plant or feeder. So, when fall comes, don’t worry. It’ll only be a few months before the gardens, backyards and forest edges are suddenly brighter – illuminated by the lively show of the Ruby-throated Hummingbird.

Recipe: Hummingbird Food 1. Mix 1 part sugar with 4 parts water. 2. Bring to a boil, then cool. 3. Fill feeder. Store extra food in fridge for up to 2 weeks. 4. Change food every week to prevent mold and bacteria. Change it every 2-3 days when temperatures are above 85 degrees.

Branching Out is printed on 100 percent recycled paper using soy ink. It is produced using 100 percent wind power. Please recycle.

How can you help? DIY Bird Bath Like most songbirds, Bluebirds love to bathe. Bird baths can help them remove dust, loose feathers and parasites. It’s important to keep bird baths clean to prevent algae growth, disease and pesky mosquitoes.

1. Ask an adult to help you pick out a large saucer or shallow bowl to be used for your bird bath. If you find more than one, you can put them at different heights on wide railings, tables or stumps. 2. Fill your bird bath with fresh water at least every 2-3 days. 3. Find a brush or sponge that will be used only for cleaning your bird bath. Remove leaves and scrub your bath weekly. If it gets really dirty, mix a splash of white vinegar with some water to use as a safe cleaner. Never use store bought soap or detergent.

Bluebird Report from the 1st Tall Tulip Poplar By Earl the Squirrel (with help from Idalina Walker) Today I am happy to announce that we have new additions to our neighborhood. The bluebird family has had chicks! Mr. and Mrs. Bluebird moved to the Nature Center a month ago. First Mr. Bluebird flapped his bright blue wings for Ms. Bluebird who thought that he was very grand indeed. Then he went and found some juicy insects for her. She was delighted. With all his flapping and gifts of food, she thought he’d make a great dad. So they set off to find a home. Bluebirds are cavity nesters. That doesn’t mean they have holes in their teeth. It means they like to live in holes in trees. The best holes are the big ones left behind by woodpeckers. Sometimes it can be hard to find a natural hole. Luckily, some nice people have put up bird houses to help. The pair that moved in by me found a lovely bluebird box put up by the Nature Center staff. Mrs. Bluebird was very busy building the nest. She gathered materials like grass and pine needles to weave together inside the box. She even lined the nest with soft things so their chicks would be nice and cozy. Mr. Bluebird carefully guarded the nest. Nest building is hard work and can take as long as a week. When this job was done, Mrs. Bluebird laid pale blue eggs, one per day until she had five. For two weeks, Mrs. Bluebird sat on the eggs to keep them warm, while Mr. Bluebird brought her food. After all their hard work, the eggs finally hatched. Now there are five chirping nestlings (baby birds) to feed. The new parents fly back and forth bringing yummy insects for them to eat.

Scrambled Eggs?

Momma and Pappa Bluebird also clean the nest by taking out the chicks’ bird droppings. Their babies are mainly eating caterpillars and soft insects now, just like you ate soft food as a baby. As they get older, they will try more exciting foods like big beetles, grasshoppers, crickets and spiders. After about 3 weeks, they will leave the nest and try out their wings. That is when we call them fledgings. Don’t be surprised to see them hopping on the ground and sitting in the bushes while they are learning to fly and catch food on their own. No need to pick them up or try to rescue them. Their parents are almost always nearby looking out for them—just like human parents.

Calling all fairies young and old! We invite you to experience the magic of gossamer wings, fairy wands and enchanting tales. Sip fairy tea and enjoy refreshments with the Fairy Queen. Make crafts, find hidden fairies, explore a woodland trail filled with fairy houses, and help to build a fairy house from natural materials.

Attracting butterflies seems simple enough - plant some nice flowering natives, and they will come. This approach can work, but a little more planning will likely yield more success. Even though your goal may be to attract adult butterflies to your yard, long-term success requires supporting butterfly species throughout their entire life cycle. Food requirements are very different between adult and larval butterfly stages, mainly because the differing mouth parts dictate the types of food consumed. Plants that nourish the leaf chewing caterpillars (larvae) are not necessarily plants that provide the nectar needed by the adult. Generalizations are dangerous. Not all caterpillars eat leaves – some eat flowers, fruits and seeds. Not all adult butterflies sip nectar – some feed on tree sap, rotting animal matter and other organic material. Similar to some other insects, there are a few species that do not feed at all as adults living off food reserves from the larval stage long enough to mate and lay eggs. However, this is more the exception than the rule.

Tips to attract butterflies:

• Grow a mix of both host plants for the larval caterpillars, and nectar plants for the adults. Many trees and shrubs serve as host plants and overwintering sites, whereas sun-loving flowers serve as nectar sources. • Provide native flowering plants throughout the growing season. Include early, middle and late season bloomers. • Eliminate the use of pesticides, especially insecticides. • Leave dead foliage of many perennials until spring to provide winter cover. • Let leaf litter accumulate where you can to provide overwintering sites for larvae or pupae of some species. • Remove invasive species and replace with natives. • Include rocks in your butterfly garden to provide warm sunning spots. Butterflies are cold blooded and need a nice sunny place to warm up when it is cool. The lists of host and nectar plants are long and vary by species. Remember that the more species of flowering plants, the more species of butterflies you will attract. You can’t go wrong with these three top bets for nectar sources: Butterfly Weed (Asclepias tuberosa), Purple Coneflower (Echinacea purpurea) and New England Aster (Symphyotrichum novae-angliae). You may already have many of the caterpillar host plants in your yard which can include herbs such as dill, flowering plants such as the milkweeds and coneflowers, and trees such as oaks and tulip poplars.
