Bluebird Monitoring Program at Morris Arboretum



Tracy Beerley, McCausland Natural Lands Horticulturist

Do you enjoy spending time outdoors and have a passion for birds? Perhaps you would be interested in joining our Bluebird Monitoring Program at Morris Arboretum.  This volunteer project has been organized to monitor the eastern bluebird and the nest boxes which have been mounted throughout the Arboretum.

The eastern bluebird is a migratory songbird in the Thrush Family which includes the American robin.  However, the bluebird is much smaller in size compared to this relative.  Male bluebirds are royal blue with warm red-brown breasts.  The females are much drabber in appearance yet maintain the similar elegance and shape of their counterpart.  This energetic bird is a medium-distance migrant, following patterns of north-south migration remaining in North America, and occupying the area east of the Rocky Mountains.  Bluebirds rely on insects for food.  Diving from a perch they hover over the ground to pluck beetles, caterpillars, spiders and other insects and small invertebrates.  When insect food becomes scarce in the fall and winter the birds seek fruiting trees and gulp down their juicy berries.  Bluebirds perch on wires, posts, and low branches, occupying meadows and openings surrounded by trees that offer suitable nest holes. They are cavity-nesting, building loose cup-like nests with fine grasses in cavities of trees, old woodpecker holes and man-made nest boxes which are mounted in suitable locations.

Bluebird populations are making a come-back from decline in the early twentieth century.  Contributing factors of decline included lack of suitable nesting cavities from increasing urbanization, pesticide use, and severe weather conditions.  Bluebirds also face competition for nesting cavities from the introduced European starling and house sparrow. Conservation efforts, such as the introduction of nest boxes, have been successful.  The eastern bluebird is becoming a more common sight on farmland, fence-lines, open woods, swamps and gardens. They are fairly present and a delight to see in the Natural Areas and Bloomfield Farm sections of the Arboretum.   

The Bluebird Monitoring Program was initiated this year at Morris Arboretum as a conservation effort to monitor the activity of nest boxes.  From March through July, volunteers assisted in monitoring over forty nest boxes within the Arboretum. Our findings were contributed to a citizen science based program, Nest Watch, through Cornell Lab of Ornithology.  The volunteers and I quickly learned of the immense nesting competition bluebirds face from house sparrows and natural predators. The results for this season are in; five nest boxes were used by the bluebird and a total of sixteen eggs were laid and assumed to have fledged.  We also enjoyed the experience of observing nesting swallows and Carolina chickadees.  Thanks to volunteer effort, the Arboretum was able to provide and monitor nesting habitat for the eastern bluebird.

An Unwanted Garden Invader

Phytolacca americana
Over the past couple months you may have noticed a large, shrubby plant with reddish stems and beautiful purple-black berries. What you are seeing is Common Pokeweed, Phytolacca americana. Although I often find it attractive, pokeweed is generally considered an unwanted garden invader.
Pokeweed is a native herbaceous perennial. It can grow one to three meters tall and resembles a small tree. The large, thick stems are smooth and upright, while the leaves are alternate, egg-shaped and pale green. Pokeweed is supported by a large fleshy taproot that persists through the winter after the succulent stems have died back.  Pokeweed flowers are small and white and give way to conspicuous green berries that ripen to a deep purple-black color. Even though the fruit may look tempting, don’t eat it! All parts of the pokeweed plant are poisonous, including the berries.
In natural areas, pokeweed is an important wildlife plant. Berry-eating birds, such as Northern Mockingbirds, American Robins and Cedar Waxwings, load up on pokeweed berries. Many mammals including gray fox, raccoons, and white-footed mice enjoy the fall fruit as well. Both birds and mammals are directly responsible for the spread of pokeweed seeds. Despite pokeweed’s wildlife benefits, it is generally considered a weed in the cultivated landscape. Pokeweed grows very quickly and will shade out desirable bedding plants if it is allowed to grow. In many cases, pokeweed is not an aesthetically pleasing addition to a garden bed.
Pokeweed is fairly easy to control once you have identified it. The plant can be destroyed simply by digging up the taproot with a spade or soil knife. If possible, try to remove plants before they form fruit. Otherwise, the animals in your area will help spread this weed throughout your yard. Although it is probably too late to stop the spread of seeds this year, keep an eye out for new plants in the spring. In the meantime, happy weeding!

Gloomy garden days, the best kept secret

Most people think of visiting a public garden or park on a picturesque sunny day, right?

Of course, we think every day is the best day to visit! But in particular, overcast days can be a great, yet often overlooked, time to visit the garden. In case you're skeptical, here are a few reasons why a seemingly gloomy, gray day is a visitor's best kept secret:

Beat the Crowds
Because the typical response to a cloudy day is to shy away from outdoor excursions, it often means less crowds in our gardens. Take this opportunity to stroll through the grounds like it's your own secret garden!

Cooler Temps
Generally speaking, clouds act as a "heat shield". Much of the incoming solar radiation from the sun is reflected or absorbed by the clouds, resulting in slightly cooler temperatures.

Optimum Photography Conditions
The even white light of an overcast day is great for outdoor photography. Sunlight is gently diffused by the clouds, eliminating harsh shadows and extreme highlights. If shooting with a standard digital camera, use the "Portrait" setting for great outdoor images.

When is your favorite time to visit the garden?

What to do with all that summer energy?


Summer's here: It's hot, the days are long, and the kids are full of energy!
Camp and swim clubs provide daytime relief for many during these school-free days, but what to do when the sun starts to set and the kids are still searching for something to do?

Thursdays to the rescue!
Morris Arboretum is open late (until 8:30pm) every Thursday during the summer months. It's a unique opportunity to pack a picnic dinner, bring a blanket, and enjoy the garden in a light that's not typically available to visitors. Kids will love catching fireflies too!

If you're looking for something a bit more high energy, be sure to come down this Thursday, July 18 for Let's Move! Garden Dance Party. The Let's Move! initiative was launched by the First Lady, Michelle Obama, to help solve the challenge of childhood obesity and promote a healthy future. Sounds by Shelly Disc Jockey Services will be on hand to lead the party in fun and engaging games and choreography. Free with admission. 

Love live music? Back by popular demand is our XPN Kids' Corner Concert Series! This year's line-up includes the amazing sounds of Alex & the Kaleidoscope Band, Trout Fishing in America, and The Suzi Shelton Band. For the first time, we are offering advanced online ticketing. Purchasing tickets early saves money and time at the gate on the night of the event. Don't forget your lawn chairs and blankets, although we're sure the family will be too busy dancing to use them!

Spring 'Yard Work'


by Jessamine Finch, Hay Honey Farm Endowed Natural Lands Intern

About once a month or so, the horticulture staff unites for a morning to undertake a large job made much more manageable - and enjoyable - when tackled as a group. This past Tuesday was a “project day” in the natural lands area, under the guidance of Natural Lands Horticulturist, Tracy Beerley. Having labored diligently over the winter months to remove invasive plants from Penn’s Woods and along Paper Mill Run, Tracy was able to select native tree and shrub species to fill these newly emptied spaces. The planting list included sugar maple, red maple, mountain laurel, rhododendron, and winterberry holly. The beautiful weather made for a wonderful day, and we look forward to seeing these plantings thrive and mature in the years to come.  

All work...

....and some fun, too!

Pausing for the little things:
One member's insight into birding.

Most people can watch birds from the comfort of their homes.  In fact, according to a 2003 U.S. Fish & Wildlife Service birding report, 88% of birders are backyard birders while 22%, or 18 million Americans, take trips away from home for the sole purpose of observing birds. Though birding has been a popular activity for a couple decades, some people are hesitant to go on birding trips due to lack of knowledge about the field. Fortunately, Susan Marshall, birding enthusiast and Morris Arboretum member, agreed to share her insights and tips on birding with us.

Q1. Hi Susan, how did you become interested in birding? Have you been birding for quite a while?
Birding has always been something on the back of my mind. My husband and I would hike, but not stop and take a look at the little things. After we retired, we looked for activities that we could enjoy doing together, so we signed up for birding classes with Ruth Pfeffer, whom I now consider a friend. I really enjoyed it and wanted to continue learning more.  Ruth has been a great teacher and influence. 
Birding has now become a large part of our lives and we incorporate it into our travels.  For example, when in Florida, we visited the Everglades, Corkscrew Swamp Sanctuary, and The J. N. "Ding" Darling National Wildlife Refuge. 
We recently caught sight of the Least Bittern – birding is a great hobby, it’s one of those things you don’t learn completely so it never gets boring.

Q2. What steps do you take to improve your knowledge and recognition of birds?  How do you know when it is the best time to spot birds?


You can approach birding from multiple ways – audio experience, make a life list (though it is not our focus), observe bird behavior, or enjoy birds when out in the woods.
One of the things I enjoy about birding is that it is an excuse to be outside. My husband and I used to have jobs that kept us indoors a lot, and now we can spend much of our time outdoors. It’s helpful when guides point things out and talk about bird behavior.  A friend and I were recently talking about birding as a way of living in the moment while enjoying nature. 
You can catch birds at any location best during migration. Also, after the sun comes up, the insects are buzzing around, attracting birds.

Q3. What have been some of your favorite Morris Arboretum birding trips?  Do you ever submit your photographs to online publications?

My husband and I have shared a few trips; Costa Rica, in particular, was a fabulous experience. We’ve visited three times already. It’s perfect because there are a variety of birds to see and there isn’t a large time zone difference. Magee Marsh in Ohio, with its large concentration of spring warblers, is a wonderful regional spot. Birding has allowed me to visit places I might never have explored otherwise!
Q4. What advice can you provide to a novice birder or someone who is intimidated by lack of bird knowledge?
A good way to learn more about birding is to register for birding trips and walks, get a basic birding field guide, and learn from your guides. Birders are usually very nice and will help you if you have questions. Also, you definitely need a decent pair of binoculars – they make such a difference! Audubon Magazine and the Nature Conservancy have lots of information on birding as well. 
Now that you’ve gained a bit of insight on birding, you might want to explore some of the Morris Arboretum’s birding trip offerings  this spring!

Deep in the Weeds, Photography by Rob Cardillo

If you haven't stopped by the Visitor Center in a while, there is a striking new addition to the Upper Gallery you won't want to miss. Deep in the Weeds is a colorful, vibrant exhibit from Philadelphia photographer, Rob Cardillo.

Like people, plants are prone to mingling. Reaching for the sun, embracing tendrils, crossing stems, they're woven into tapestries of shifting textures and colors. In roadside weed patches, native plant communities and even well-tended garden beds, Rob Cardillo has framed nuanced gestures between twig and leaf, petal and pod, creating layered images with a photosynthetic pulse. Through his lens, we see abstract beauty in the interplay of shapes, color and light, yet the images remain fully grounded and invite us to commune with nature's silent social network.

Rob Cardillo has professionally photographed plants, gardens and the people that tend them for over twenty years.  His work appears regularly in Horticulture, Country Gardens, Organic Gardening, The New York Times and many other magazines, books and advertisements. To see Rob Cardillo’s work visit www.robcardillo.com


























Deep in the Weeds, photography by Rob Cardillo
On display beginning February 3 -  Opening Reception March 17, 1:00 - 3:00pm
Located in the Upper Gallery at Widener Visitor Center

The Philly Bees' Stake in Pollination

by Stephanie Wilson, Endowed Plant Protection Intern

This past fall, I have been running around Philadelphia with an insect net in hand, surveying the wild bees (non-honey bees) in Philadelphia. The very fact that you can grow many vegetables and flowers in the city is because wild bees are present and pollinating. But very little is known about these city slickers and how they survive such a rough habitat: pavement instead of bare ground (which they dig nests in), patches of flowers instead of rolling meadows, and competition from non-native bee species that are slipping in through our shipping ports. This is exactly what I am researching as part of a survey of the flora and fauna that the USGS is conducting.

Longtime Botanist Retires From Morris Arboretum

Today, in a world that revolves around technology, one of Ann Rhoads’ greatest pleasures is taking her grandchildren for woodland walks. As someone whose career has involved spending a significant amount of time outdoors, Ann has always encouraged people of all ages to appreciate and take pleasure in the natural world. In January, Ann retired from a long and prolific career at the Morris Arboretum. Ann served as Director of Botany at the Arboretum from 1976 to 2000, at which time she stepped back to the position of Senior Botanist in order to allow now Director Tim Block to assume the position.

An expert in the flora of Pennsylvania, Ann and former Arboretum Director, Bill Klein, built on work initiated in the 1930s by Edgar T. Wherry by creating the Flora of PA database. Today the database holds approximately 400,000 specimen records from the major Pennsylvania herbaria. During her tenure, the botany department at the Morris Arboretum also produced several important books.  In 1993, The Vascular Flora of PA, Annotated Checklist and Atlas by Rhoads and Klein was published by the American Philosophical Society.  The Plants of Pennsylvania, An Illustrated Manual by Rhoads and Block, first published in 2000 by the University of Pennsylvania Press, has proven to be a valuable resource both within and outside the state. A second edition, incorporating recent taxonomic changes, was published in 2007. Trees of Pennsylvania appeared in 2005, and Aquatic Plants of Pennsylvania was released in 2011.

Ann has also taught and mentored students through the years both at the Morris Arboretum--supervising or co-supervising the Plant Protection and Pennsylvania flora interns, and as an adjunct professor at the University of Pennsylvania, where she taught Plant Systematics and Field Botany.  An active spokesperson for environmental issues, Ann was instrumental in drawing attention to the issue of deer overabundance and its severe impact on the structure and composition of Pennsylvania’s forests and natural areas. She has served on statewide committees and developed reports to help educate the public about the importance of this issue.

Even though she is retiring from the Arboretum, Ann says she will continue to expand her knowledge of plants, and will still be involved at the Arboretum, helping out in botany and maybe even writing another book.  In the meantime, her message not only for her grandchildren, but for all of us is a simple one- “Get out into the woods!”

Checking on our young ones...

by Jamie Berlin, Alice & J. Liddon Pennock, Jr. Endowed Horticulture Intern

After trees have shed their leaves and the cold weather moves in, the Arboretum begins to move at a slower pace. During these months, the Arboretum staff has time to check on younger plantings and newer transplants. By visiting these plants individually, staff can evaluate health and initiate proper management practices. Younger trees are more vulnerable to the elements, so checking on them annually can help reduce problems in the future.

After checking that all accessioned plants are alive and accounted for, staff can focus on:
  • Minor pruning - cutting off branches that are rubbing one another or that might be a problem in the future.
  • Staking - protecting the young plants from buck rub (the practice of male deer rubbing their antlers on the stems of small trees to remove the velvet from their antlers).
  • Trunk protection - using netting around the base of the trunk to stop animals, such as groundhogs, from eating the bark.
  • Insect damage - taking note of the insect causing the damage, evaluating if it will cause a major problem to the plant, and taking the necessary management steps, such as pruning or spraying.
  • Labeling issues - accessioned plants within the Arboretum are assigned a specific number so they can be tracked over the years. If tags fall off, or are missing, this needs to be dealt with right away.
