Empty Nest Syndrome

For the last handful of years, my family has had the good fortune to have a pair of Eastern Bluebirds grace the nest box in our tiny suburban backyard. When we set up a box this spring in our new backyard (a suburban oasis I wrote about here), I feared we might not see any action this year because several dead trees on our property provide natural cavities. Typically, we see males start to check out the box for a period of days beginning in February, perching on top, fluttering their wings, and flying in and out carrying nesting material. Once a female is sufficiently impressed, she takes over all of the nest construction and egg incubation, and the male delivers food to her while she is on the nest. I only saw a bird fly into the house once or twice after we set it up, and never with nesting material, so when I peeked in the box in mid-April, I was surprised to discover not only a nest, but five gorgeous blue eggs.

Eastern Bluebirds generally lay four to six eggs which are incubated for about two weeks.

Every few days, I checked on the nest to monitor the progress of the clutch. Aside from my personal interest in the nest’s success, I had registered to monitor the nest with the Smithsonian Migratory Bird Center’s Neighborhood Nestwatch program, a citizen science program that provides scientists with hard-to-get data about the survival rate of backyard birds. Nestwatch scientists also visited my home recently to band some of my backyard birds so that I can monitor them and record sightings into their database. Participating in such programs is a great way to spark curiosity and excitement for birds in kids and adults alike, as well as a way to contribute valuable data that scientists can use to guide conservation measures. If you have an accessible, active nest in your yard, I encourage you to register with Nestwatch and record your observations, but do make sure to read the important nest monitoring guidelines first so that you don’t hinder the success of the nesting efforts.

Scientists from the Smithsonian’s Nestwatch program visited our home in April to catch and band birds for us to monitor. The program provides valuable data for scientists about backyard bird populations.

Bluebird babies take about two weeks to hatch and just another two weeks to fledge. As with all babies, they grow up way too fast—in just a blink of their sleep-deprived parents’ eyes. Every three days or so, I’d watch for the parents to fly off, then take a quick peek in the nest and snap a photo.

Watching the adults bring food back to the nest was fascinating. Each afternoon after work, I sat on our front steps to enjoy the show from a distance. Mama bluebird brought back much larger prey items than Dad did, and she was also more reluctant to enter the nest box while I was watching than he was. I watched her bring various large flying insects or earthworms back to the nest on several occasions, but I rarely saw her go in. I’d take my eyes off the box for just a moment only to turn back and see her flying off out of sight. One afternoon she even brought a lizard back to the nest!

Daddy Bluebird was an attentive father. He brought smaller food items to the nest, but seemed to make more frequent visits.

The female pounded and pounded this hapless lizard on the top of the nest box! I didn’t notice until I cropped my photo that the lizard appears to have already dropped its tail—so much for that defense mechanism. I’m not sure, but I think she gave up and flew off with it rather than feed it to her young. It would have been quite a mouthful!

As the chicks neared two weeks of age, I frequently saw them poke their heads up to look out of the box.  I knew their time to fledge was approaching and hoped it wouldn’t occur the day I would be out of town for a work event. In spite of careful observation in past years, I’ve never seen the babies leave the nest, and I was hoping this year I might get lucky. When I checked the box first thing in the morning after my work trip, I was crushed to discover that the nest was empty. Not only had I missed their departure, they had chosen the first cool, stormy day in almost three weeks to do so. I looked high and low in all the surrounding areas. In my experience, baby birds typically hang around low to the ground for a day or two, or at least up in the trees in the area near the nest, but these baby bluebirds were nowhere to be found. I listened for their begging calls and could detect nothing, and I saw no sign of the parents. I worried that a snake had taken the whole clutch before they even left the nest (which is exactly the reason why birds leave the nest as soon as they are able, often when they haven’t mastered flying yet).  I worried that a predator had gotten them after they left the nest.  I worried that they had gotten wet or gotten lost and succumbed to chill. Feeling disheartened, I headed to work.

The babies are almost ready to explore the world. Their heads popped up each time their parents visited. 5/15/15

When I returned home that afternoon, I immediately set myself on the front steps with my binoculars. After several minutes I saw the male fly in and grab an insect from the ground and fly off into some distant trees. Several minutes later I saw the female do the same, but I couldn’t make out where they had gone. Surely the babies weren’t that far away? Were the adults just returning to business as normal? The sinking feeling returned. Determined to know more, I watched several more minutes until the male returned to the yard again. This time as he flew off, I changed my vantage point and watched as carefully as I could with my naked eye as he landed at the top of a tremendously tall tree. I could just make out the fluttering of wings and distant begging calls. The babies were safe—and apparently very well equipped to get off the ground!  Phew!  As much as I had hoped they would hang around a little longer, I was relieved and happy to see them safe and sound—the best cure for empty nest syndrome. If I’m lucky, the parents may return to raise one more clutch before the summer is over!

Note about bluebird conservation:

I’ve commented in the past that I must have walked through the first four decades of my life with blinders on not to have noticed the beauty and diversity of bird life around me, but I think that even had I been paying more attention growing up, I wouldn’t have been likely to see an Eastern Bluebird in my backyard. Eastern Bluebird populations steeply declined in the early part of the 20th century as habitat loss and competition from introduced species such as European Starlings and House Sparrows made nesting holes increasingly difficult for bluebirds to claim. Fortunately today, in spite of the tremendous pressures facing birds, the Eastern Bluebird seems to be doing just fine. The establishment of bluebird trails and other nest box campaigns beginning in the late 1960s helped Eastern Bluebird populations rebound by almost two percent per year between 1966 and 2010.* The success of these efforts is an important reminder that when we work collectively to make small conservation actions, we can effect significant change. So, leave those dead trees standing (60 species in N. America are cavity nesters!), or put up a nest box or two (make sure it is designed to keep out the larger non-native and more aggressive starlings). I’m doing my part!  *www.allaboutbirds.org/guide/Eastern_Bluebird/lifehistory

Suburban Safari*

I can’t believe it has been more than six months since I wrote my last blog post.  It hasn’t been for lack of inspiration. Aside from the demands of careers and raising two middle-schoolers, my husband and I have been busy settling into our new home on 1.6 acres after the long process of zoning, designing, and building (and keeping our old house in pristine condition until it sold). Our “subdivision” (four lots, two currently undeveloped) also has shared access to a one acre lake and adjoins a large wooded park of more than 100 acres. I am in wildlife heaven. Although minutes away from conveniences, when I pull into our driveway at the very end of our street, I feel like I’ve entered a small patch of wilderness.

The view from the lake looking toward our house

The backyard is a small “meadow” of untamed grasses and wildflowers that run down to a brushy area along a small stream, and towering trees surround the property. I have enjoyed watching all of the different plants and trees come into bloom and trying to learn what they are. We have lots of beautiful and beneficial native plants, which I’ve written about previously, although we also have invasive English ivy and Japanese honeysuckle, unfortunately. (I’m considering renting goats to tackle this problem). We’ve added our own mark to the landscape by planting blueberry bushes and fruit trees, including a native persimmon tree, which I’ve heard is a favorite with wildlife. The edges between the yard and wooded areas are lined with wild blackberry bushes, their blooms the promise of summer cobblers if the birds are gracious enough to share. The first shrubs I bought and planted were three native red buckeyes, which I’d learned are an important early food source for migrating hummingbirds. I had to laugh at myself when they bloomed a few weeks later—along with the dozens of other red buckeyes in the woods around the house. (If you want some, I can hook you up!)

Wild blackberries are abundant in the yard. Hopefully the birds will share.

One of the native red buckeyes I planted (then discovered we have them everywhere!) This is an important early food source for hummingbirds on their northern migration.

Wildlife viewing is a daily pursuit in our new home. A pair of Red-tailed Hawks live nearby, and two Barred Owls call almost nightly. Four white-tailed does regularly pass through the yard, occasionally accompanied by a buck. Recently, we saw two gray foxes gamboling about in the backyard early one morning, though our occasional sightings are typically of a single individual, usually after dark. We’ve heard them rustling in the brushy area on the side of the house during the day a few times lately; the alarm calls of the chipmunks and squirrels give them away. Are they hunting during daylight hours because they have young mouths to feed? In addition to the foxes who share our home, we frequently find coyote tracks near the stream, as well as the tracks of opossums and raccoons.

The yard is bustling with bird activity, offering boundless opportunities for new discoveries—-my yard list is already up to 66 species! The thickets attract towhees, thrashers, wrens, and cardinals, while the tall, grassy areas attract sparrows, finches, and doves. Dead trees provide a bed-and-breakfast for woodpeckers, nuthatches, and chickadees, as well as snags for flycatchers to sally out to snatch insects in midair. Having the lake nearby means we never know when we might see our local Great Blue Heron fly through the backyard or hear the rattling call of kingfishers. Spring migration brought some delightful and unexpected surprises like Indigo Buntings, Rose-breasted Grosbeaks, Scarlet Tanagers, and a few species of neo-tropical warblers.

I wonder if this is the Song Sparrow that serenades me every morning. His morning song is different from the one he sings later in the day.

House Finch, another local resident. House Finches are not native to the Eastern United States. Captive birds were released on Long Island in the 1940’s by pet shop owners selling them as “Hollywood Finches” who wanted to avoid being persecuted under the Migratory Bird Species Act, which prevents citizens from keeping any native bird in captivity without a USFWS permit. The birds flourished and spread and are now naturalized in most of the United States.

Clearly I have plenty of inspiration for writing, yet what little free time I can carve out of my day is often spent just sitting outside on the porch quietly watching and listening to my surroundings.  Who wouldn’t rather be outside enjoying nature than sitting at a computer writing about it anyway?!  I feel gratitude daily for the opportunity to live in a place where I feel rooted in nature while staying connected to family and friends in our suburban community. I am thankful, too, that I can share this small patch of wildlife-friendly habitat with my wild neighbors. Creating such patches, even on a small scale, is one of the most important and empowering conservation actions that individuals can make, and collectively our actions can provide tremendous benefits for wildlife and the environment. You can even have your yard certified as a Backyard Wildlife Sanctuary, a designation I plan to pursue (once the goats take care of that invasive honeysuckle!).

I look forward to having lots more “wild” stories to tell. We’ve had some real excitement here this month watching the pair of Eastern Bluebirds that nested in our birdhouse, so stay tuned for an upcoming post documenting their story. You won’t believe what mama bluebird brought to the nest for her babies one afternoon! Thank you for sticking around, and look out for my next post soon.

*Note: Suburban Safari was actually the first idea I had for the title of my blog, but when I did a search for the name, I discovered that it was already the title of a book, which I proceeded to check out of the library and enjoyed reading very much. A review on Amazon says this about the book: “The suburban lawn sprouts a crop of contradictory myths. To some, it’s a green oasis; to others, it’s eco-purgatory. Science writer Hannah Holmes spent a year appraising the lawn through the eyes of the squirrels, crows, worms, and spiders who think of her backyard as their own. Suburban Safari is a fascinating and often hilarious record of her discoveries: that many animals adore the suburban environment, including bears and cougars venturing in from the woods; how plants, in their struggle for dominance, communicate with their own kind and battle other species; and that ways already exist for us to grow healthier, livelier lawns.”

Springing Forward

Although Old Man Winter is still flexing his muscles here and there (Atlanta expects temperatures to drop below freezing again this week, and my northern friends are bracing for another snowstorm), we are definitely on the threshold of spring. With the arrival of warmer weather and lengthening days, the signs of spring are everywhere – blooming spring ephemerals, budding trees, birdsong, and baby squirrels!  Here are just a few of the tell-tale signs I’ve seen in recent days that remind me that warmer, greener days are ahead.

Trout Lilies are an early herald of spring.

Trout Lilies are an early herald of spring.

One of the earliest heralds of spring, Trout Lilies grow in sizeable colonies and are named for the mottled leaves which bear some similarity to the markings of brook trout. Like other spring ephemeral wildflowers, trout lilies are perennial woodland plants that sprout early in the spring to take advantage of the full sunlight. They bloom and quickly turn to seed before they are shaded out by the canopy trees. Once the forest floor is in deep shade, the leaves wither, leaving behind only the underground roots and bulb. Some other ephemerals to look for while walking in Eastern woods are Hepatica, Bloodroot, Trillium, and Jack-in-the-Pulpit.

Although we usually think of trees being their most colorful in the fall, they put on a variety of colorful displays in the spring, too. Aside from the showy blooms of flowering trees like the Dogwood or Magnolia, many other common deciduous trees bear colorful flowers in spring. Maple flowers, for example, can be green, yellow, orange, or red, and while the flowers are small, the effect of a whole tree in bloom is beautiful. Later, the flowers of the maple tree yield seeds called samaras – better known as “helicopters” or “whirlybirds” for the way they are shaped to spin as they fall, which helps to carry them great distances on the wind for dispersal. These seeds are an important food source for a variety of wildlife.

The birds are singing! (Carolina Wren)

The birds are singing! (Carolina Wren)

You’ve probably noticed that the birds are a lot more vocal as the days grow longer. The increased sunlight triggers hormones in birds that induce them to sing, especially the males, but the females of many species sing also. Vocalizations fall into two general categories, songs and calls. Songs are used to attract mates, declare territory, and bond with family members. The shorter calls are used to convey information about food sources, warn of danger, and help family members stay in touch as they forage. The Northern Mockingbird, named for its ability to mimic the songs of other birds, has one of the most expansive repertoires, copying songs from other species and incorporating them into thousands of variations. Most people are surprised to learn that Georgia’s state bird, the Brown Thrasher, has even more songs than the mockingbird! In fact, it has the largest repertoire of all North American birds. Early spring is one of the best times to watch birds – before the canopy hides them from view and before they have young mouths to feed and protect.

Northern Mockingbird

Northern Mockingbirds are expert mimics with hundreds, if not thousands, of variations in their songs (even when standing on one foot as this bird is, ha ha).

Finally, I know that spring is truly here when the wildlife center where I volunteer starts receiving a steady inflow of displaced and orphaned baby squirrels and other young wild animals. Already we are caring for close to twenty tiny squirrels, and that number will double, or triple as the season progresses. For me, making and warming formula, feeding bottles, and washing an endless stream of dishes and dirty laundry have become as closely associated with spring as any other of the tell-tale signs. So please, hold off on your tree pruning, keep your cats indoors, and when possible, place any young mammals or birds you find on the ground back in the nest. Our hands are full already!
