Introduction
For centuries, viewing wild animals has been a hobby for people. In the 1700's, birds
were documented in books for their beauty, and more recently bird watching has
increased as a recreational activity. There are ample opportunities to view wildlife at
zoos and wildlife parks, such as the one located locally at Penn's Cave. These close
encounters provide nature lovers with opportunities for endless enjoyment.
With such an interest growing in wildlife, it is important to note that animals are losing
their natural habitat at alarming rates. Most of this is due to development, habitat
fragmentation, and deforestation. For those interested in wildlife, there are things we
can do to help.
The following document serves as a guide to attract species local to Centre County,
Pennsylvania; for example blue jays, American toads, Eastern gray squirrels, and white-
tailed deer to a backyard setting. Homeowners like you can use the simple steps
provided to entice animals to your home. The landscaping guidelines given will not
only make appealing additions to your property, they also act as sources of food, cover,
and water for the animals.
This guide will begin by discussing plants conducive for alluring butterflies. Then the
subject of birds is discussed, including information on bird baths, feeders, nest boxes,
and preferred tree and plant species. The benefits of constructing a pond setting for
amphibian lovers are covered next, followed by a section on mammals. The mammals
section is broken down into squirrels, rabbits, and deer. Important safety tips to keep in
mind while coming into contact with animals are provided, along with guidelines to
prevent animal damages. By applying these guidelines, you'll have animals visiting
your yard in no time.
The tranquility of the outdoors and its inhabitants await you. Happy viewing!!

Butterflies Creating a Butterfly Garden
Butterflies are beautiful creatures that are easily
overlooked in today's society. They are observed during
the day, especially during July and August when it's
warm. By planting a few preferred plant species for food,
you can enjoy marveling at these insects as they bask in
the sun or flutter past your window.
Getting Started
Begin by making a list of butterflies native to the area that
you'd like to attract to your property. This information
can be obtained from a field guide, such as the National
Audubon Society Field Guide to North American Butterflies.
After choosing the species of interest to you, the most important attractant will be its
favored plant species. Butterflies need nectar plants for the adults to feed on as well as
host plants for the caterpillars to consume. The female must lay her eggs near a host
plant because once the larvae hatch, they cannot move far to find a host plant to feed
on. Some top plants for butterflies are butterfly bush, purple coneflowers, New
England aster, milkweed, and marigolds (1). A list of native Pennsylvania butterfly
species and their preferred host and nectar plants follow in the two charts below:
Species Host Plant
American Snout (Libytheana carinenta) Hackberry
Common Buckeye (Junonia coenia) Plantains, Snapdragons, Gerardias
Hackberry Emperor (Asterocampa celtis) Hackberry
Monarch (Danaus plexippus) Common Milkweed
Mourning Cloak (Nymphalis antiopa) Willow, Aspen, Cottonwood, Elm
Painted Lady (Vanessa cardui) Thistle, Hollyhock, Sunflower, Daisy

Creating Your Garden
Now that you've secured all your plants, you're ready to begin creating a butterfly
haven. For your own aesthetic purposes, you may want to draw out a landscaping plan
of where to place each component. A good plan to follow is to place perennials in the
back portion of the garden and annuals in front. This makes replacing the annuals each
year easy. Also, provide areas where there are tall plants, medium sized plants, and
shorter plants for variation. If you choose to use pesticides, do so sparingly.
Make sure there are plenty of open sunny areas in your garden. Butterflies are most
active in the sun, flying best when temperatures are in the 70s. Since butterflies are
cold-blooded, they need to bask in the sun to get energy for flight. Provide areas, such
as rocks, for this behavior.
In bad weather, butterflies need to be protected from the elements. Shelter from the
wind can be obtained by planting rows of shrubbery, including Honeysuckle,
Hawthorn, and Spice bush(2). A butterfly house can be purchased or made to add
security as well as serve as a decoration for your home.
Now that you have most of your elements in place, the last thing you need to include is
a water source. Believe it or not butterflies still need to drink! They use the water to get
nutrients such as salts that they don't receive from the nectar sources. You can do
something as easy as dig a shallow puddle or fill a bucket with sand and keep it wet. A
bird bath would work as well- and would attract even more wildlife to your yard!
5
Waiting for the Butterflies
If you've provided all the elements discussed, the butterflies
will find all the conditions they need to thrive. Now it's time
to be patient and wait for them to come to you. However, you
could make the experience even more enjoyable by raising
your own butterflies! Butterfly kits come with live caterpillars
which you can grow and release into your garden. If you
chose to do this, follow the instructions and don't release
them into your garden until they've
emerged from the cocoon.

Birds
Birds need three elements in a habitat to thrive: food, water, and shelter. These
elements are easily placed into your current backyard setting by implementing bird
feeders, birdbaths, and trees or shrubs that provide adequate cover.
Providing Adequate Food
There are several types of feeders available for birds. For
ground feeding birds including robins, doves, and
cardinals, a platform feeder is best suitable. A hanging or
tube feeder can be hung on a tree or post and will attract
such species as nuthatches, finches, chickadees, and
sparrows. Be sure to clean feeders regularly with a 90%
water and 10% bleach solution (1).
Different types of bird feed will attract different types of
birds. If there are particular species you hope to attract,
pick a bird seed they prefer. Sunflower and safflower seeds
are good for protein and fat and provide energy to the bird.
Mixes of these types of seeds can also be found. Another
alternative is suet bird feed, which is sold in bars or cakes
and is preferred by woodpeckers, nuthatches, chickadees, and titmice. It is important to
be sure when giving food that it is kept in a dry place and not moldy. The chart below
shows types of feed and the species of bird attracted:

Cardinals, Bluejays, Chickadees, Nuthatches, Titmice, Gold finch,
House finch, Juncos, Sparrows
Safflower seeds

Adding a bird feeder to your yard is a great start, but you can also add plants that will
provide food. Evergreens, such as white pine, cedar, spruce, and yew trees provide a
source of berries or seed filled cones. Deciduous plants provide not only a place to
perch, but also seeds, nuts, and berries. Some favorable species are cherry, crabapple,
hackberry, oak, and serviceberry. Also include shrubs of honeysuckle, barberry, and
holly. Certain species, like the hummingbird, are attracted to tubular flowers that can
provide nectar. Have a diverse stand of vegetation present and be aware of when they
are providing seeds, nuts, or berries. The birds need to have food throughout the whole
year!
Species of birds will be around all year as residents, while others will migrate during
the colder months. For the resident birds, such as the black capped chickadee and
house sparrow, winter food should be available beginning early in the fall. The birds
will become dependent on the food source, so feeding must be continued throughout
the winter. For migrating birds, winter migration commences by mid-December and
spring migration begins in mid-February (2).
Accessing a Water Source
It is important to add a clean water source for birds to drink from, whether you choose
to include a birdbath, pond, or water fountain in your plans. "The sound of moving
water is magnetic to most wild birds and will draw them from greater distances for a
cool drink or bath" (3). Water depth should not exceed 3" (4). Make sure the surface of the
water source is constructed with stones, sand, or concrete to ensure good footing.
Placement of water is also key. Many birds prefer
to drink in open areas, where they will be able to
see predators coming. However, if you are aware
that your area is frequently visited by hawks or
other predators, consider moving the water source
closer to cover where the birds can easily escape.
Since you're creating this space for your
enjoyment, put it where you can easily observe
birds from your home.
Make sure you are providing clean water. If using
a bird bath, the water should be changed every
other day and cleaned every 2-3 days as a general
rule. Clean the bird feeder with hot soapy water.

Incorporating Protection and Cover By planting vegetation such as trees and shrubs, birds have a place to take refuge. The
same species that provide food will also serve for shelter. Plant a diversity of species
for attracting the most birds and focus mainly on native plants to the area that birds are
familiar with and will use.
Birdhouses and nestboxes are also great additions to your plans.
Nest boxes are used by birds for breeding, as many birds are cavity
nesters. Bird houses provide cover and should be placed facing away
from wind and out of direct sunlight. No nesting material or food
should be placed in these structures, unless used by owls, chickadees,
or woodpeckers, where wood chips could be included(1).

Amphibians
Frogs, Toads, and Salamanders
There are 22 species of salamanders in
Pennsylvania and many types of frogs and
toads, including the Wood frog, Spring
peeper, Gray tree frog, Green frog, and
American toad. Amphibians are ectotherms
and cannot regulate their body temperature,
causing them to hibernate in the winter and
aestivate when it gets too hot. Many
amphibians spend time both on land and in
water, but their habitats are in decline due to
fragmentation and destruction. The addition of a tranquil pond to your yard can be an
inviting home to these amphibians.
Excavating a Pond
The size of a pond’s reflective surface draws attention from these
creatures. Before beginning to dig out your pond, plan the size that
fits your property- just remember it won’t be noticed if it’s too small.
An average size for a pond is 12 ft long, 6 ft wide, and 1.5 ft deep (1). Placement of a
pond should be on level ground where water will naturally collect. It should also be in
an area with minimal risk to animals that are coming or going, so avoid patches of land
near roads. Also avoid areas that experience run-off because these nutrients can affect
amphibian development if they enter the water. Place a pond at least partially in the
shade to keep algae growth from becoming rampant.
You can begin to excavate your pond whenever the ground is not overly wet or frozen.
While digging, remove rocks and other debris. Once digging has been completed, add
a few inches of sand to the pond bed before putting in a liner. This helps to keep
anything on the bottom from puncturing into the liner.
Choose a sunny day to add the liner to the inside of the newly excavated pond. Place
the liner into the hole and secure it with bricks. Begin to fill it with water, which will

form the liner to the shape of the pond. Use some of the soil excavated for the pond to
secure the liner (2).
Keep in mind that the pond is most likely to be utilized by frogs, toads, and
salamanders if the water is still or slow moving. In addition, many species cannot
compete well with fish for resources, so if you want amphibians to visit your pond
consider not incorporating fish.
Adding Plants
Allow the pond to warm for a few days before placing any
plants into it. Vegetation is important for cover and as a
substrate for egg attachment. You want to mix a variety of
emergent plants, which are rooted in shallow areas and
exhibit most of their growth above water. Some common
species of plants include cattails and water lilies. You also
want to include submergent plants and floating plants like
duckweed.
Land elements are just as important as water elements for
these species. Add shrubs and water tolerant vegetation
around the pond to allow for increased cover and escape
from predators. Also add logs, leaf litter, and rocks to
provide cover because many will spend more time on land than in the water (3).
Creating a Toad Shelter A fun project you can create yourself is a toad shelter. Drill a hole big enough for a frog
or toad into the side of an upside down clay pot. Have fun decorating these toad
shelters, as they will increase the aesthetics of your pond area. Place these on the land
around your pond, among vegetation.

Mammals
Enticing Squirrels, Rabbits, and Deer
While these animals play an important role in nature, many people view them as
nuisances. Before taking any steps to attract these animals, make sure it is something
that you're interested in. Once being fed, it will be hard to get squirrels to leave; and
you may find that they don't have enough suitable nesting spots in trees, causing them
to sneak into your home and take refuge in your attic or garage. Also, these suggestions
may be expensive- such as planting a food plot for deer. However, providing suitable
habitat for these animals is still rewarding.
Inviting Squirrels
Squirrels can be attracted to seeds that fall on
the ground around bird feeders. These critters
have to eat their body weight each week in food
and can cause havoc on the food you've
supplied for the birds. Provide compressed
corn logs, or purchase a squirrel specific feeder.
There are also bird feeders available that are
squirrel proof. Planting vegetation for cover as
well as food will also attract these animals.
Squirrels like red maples, hickories, hackberry,
and oaks because they prefer fruit and nuts.
Being year round residents, squirrels need plenty of cover. Squirrels like to nest in
trees, so if there is not enough good nesting sites already available, consider adding
nesting boxes. Although meant for birds, squirrels may take residence in boxes made
for birds including American Kestrels, pileated woodpeckers, and wood ducks (1). If
trees are close to your home, pay careful attention to trim any branches that squirrels
could use to jump onto your roof. They may use your gutters to gather nuts and could
find a hole or chimney to enter your house.
12
Attracting Rabbits Cottontail rabbits are common throughout the eastern
United States. They are found year round, and are most
active at dawn and dusk. Pay extra close attention from
March- September, when you might catch a glimpse of
baby bunnies, also called kits, timidly munching on
vegetation.
Rabbits eat plants already common in many yards, such
as clover and dandelions. They also consume corn,
soybeans, and wheat. According to H. Lee Stribling, an
Extension Wildlife Scientist and Associate Professor at
Auburn University, "Plant cowbeans and corn during
spring and small grains during fall to provide year-
round forage. If fescue is planted, be sure to use an "endophyte-free" variety, because
other varieties can decrease cottontail reproduction" (2). During the winter, rabbits eat
the buds and bark of plants including birch, oak, maples, blackberry, witch-hazel, and
sumac (3) . Timothy, crabgrass, and bluegrass are other choice plantings.
Rabbits, like other wildlife, also need water and cover. However, water needs are
usually met by the food rabbits consume. Providing brush piles, tall grasses, and
weedy areas serve as adequate cover. Living near agricultural areas where there are
corn fields will also provide necessary nesting sites. Plant thickets of blackberry or
honeysuckle for refuge.
Enticing Deer Those that live near a wooded habitat will be most likely to
entice white-tailed deer. Food plots are a great way to appeal to
deer, especially where the nearby habitat is poor or the food is
scarce (4). Late winter and early spring are the times when deer have the hardest time
finding food, so plant perennials that will still be around during this time. If planting a
food plot is appealing to you, it is suggested that they will be most effective when they
are within a deer's home range, which is approximately 1 square mile (640 acres). Also,
it is important to place your plots at a distance of at least a half mile from roads or
gardens to minimize damages. Some forage species you could plant include corn,

soybeans, alfalfa, clover, or bromegrass. Preferred species of trees include oaks and
maples. A salt or mineral lick can be set out as well to provide further nutrients.

Safety
Precautionary Tips for Interacting with Wild Animals
Whenever encountering wild animals, there are some things to keep in mind. Wild
animals are not pets and should not be approached or tried to be tamed. Below are
some tips to keep in mind when living in close proximity to wild animals:
Protect yourself from diseases. Animals can carry diseases, making
you more susceptible to them with contact. Racoons and groundhogs
such as rabies. Rabbits get ticks and can be a host for Lyme disease.
Although not found in Pennsylvania, Chronic Wasting Disease has been a
problem in deer and other cervids throughout the United States.
Attracting these species may raise your risk of coming into contact with
this disease and others should they appear in the area. Be aware of the
potential risks and check yourself for ticks or other vectors of disease.
Don't approach a sick or injured animal. If an animal needs help,
you can refer it to professionals such as the Centre for Wildlife Care
located locally in Port Matilda.
Remove dead animals. Should a carcass of an animal be seen in your
yard, dispose of it properly. Wear gloves, place the animal in a trash bag
and throw it away or bury it. Then thoroughly wash your hands with hot
soapy water to kill any germs.
Secure trashcans. You will attract more unwanted attention from
animals by making food easily accessible. In addition to the animals
you've already attracted, you may find that raccoons or even bears could
find your home appealing.
Be cautious of animals on the road. Deer should not be attracted to
your property if you live near a major roadway. Deer have contributed to
18,000 collisions from 2004-2005 (1). Drive slowly and be alert if driving in
areas inhabited by deer.

Damages
Allowing animals to come within close proximity to your home can result in
disturbances. Rabbits and deer may eat your vegetables and garden plants, and
squirrels may find a way to enter your home. If you've created a habitat conducive to
attracting these animals, there are some ways to limit the damages they may cause:
Erect fences. Fences placed around gardens should be constructed using
posts, or metal wire that is small enough not to allow small animals to
pass through the crevices. If using a mesh fence, which can be effective
for smaller mammals such as rabbits and squirrels, be careful that they
will not become tangled in it. Constructing fences for deer should be at
least six feet high, more desirably eight to ten feet high, so it can not be
jumped over.
Eliminate access to buildings. As previously stated, squirrels will try
and find a way into your home if they do not have adequate nesting sites.
Ways to prevent this include repairing loose siding and shingles, covering
the dryer vent with a vent screen, trimming branches away from the
house, and cleaning gutters at least twice a year.
Place feeders in appropriate areas. The placement of feeders where
they can still be seen but not too close to the home will help to keep
animals further away. Also, including squirrel feeders in addition to bird
feeders and keeping them separate (around 15 feet) will deter squirrels
from damaging the feeder or robbing the birds of their food. Ground
dwelling animals, such as chipmunks, will collect many of the fallen seeds
but won't provide damage to the feeders.
Use Repellants. There are many commercial repellants that can be
purchased to deter unwanted animals from locations in your garden.
Get professional help. If animals continue to cause damages around
your home, it is best to reduce feeding until it is discontinued. If
necessary, call local professionals to remove unwanted animals. For
example, S & S Wildlife Control Services, Inc. in State College can be
reached toll free at 1-866-758-6523.

Concluding Remarks
Now that you've planted your trees, shrubs, and flowers; erected your bird feeders and
nest boxes; and excavated your pond, all that's left to do is wait. Remember to be
patient while the animals make your home theirs too. Pretty soon you'll enjoy standing
by the window just to catch a glimpse of nature's miracles.
Show off your efforts by certifying your garden with the National Wildlife Federation
as an official wildlife sanctuary. Even your neighbors will notice and be impressed
when they see the yard sign indicating your dedication to conserving the local species!
