Birds are Important to U.S. Citizens
•We watch them and feed them
•We write books about them
•We market our businesses with their
images
•We name our sports teams after them
•We choose them as symbols of our
patriotism
Why Watch Birds?
76 million Americans currently enjoy the sport of watching birds.
Birds are colorful, interesting to watch or listen to and relatively easy to attract to our backyard.
Does not require a lot of specialized equipment, just a good pair of binoculars and a field guide that helps identify the bird.
Texas is one of the premiere locations in the country for birdwatching. (614 different species in Texas alone!)
How to Identify Birds
Where Should You Start?
1. Begin by
identifying the bird
to a group.
Use features like
body shape and
size, bill shape,
length of neck and
legs, and shape of
wings and tail.
Learn to recognize shapes for quick recognition.
2. Use field marks to identify similar species.
Yellow-rumped warbler
Lark Sparrow
Canada Warbler
Louisiana waterthrush
Common nighthawk
Northern
Cardinal Scarlet tanager
House
finch
Summer tanager
Rose-breasted
grosbeak
Vermillion flycatcher
Summary on Identifying Birds
First, identify the bird at the group level and practice recognizing birds by shape alone.
Second, use field marks on the bird to identify the correct species.
Migration Facts
• 778 are migratory
• 300 species migrate to Latin America
• 19 species of shorebirds migrate 8,000 miles 1 way
• 34 species of wood warblers and 22 of the 29 species of waterfowl are shared between U.S., Canada, Mexico
Of the 852 bird species in the United
States:
Golden-Crowned Kinglet
American Goldfinch
Yellow-Rumped Warbler
Ruby-Crowned Kinglet Eastern Phoebe
Orange-Crowned Warbler Cedar Waxwing Dark-Eyed Junco

How Did Bird Migration Routes Become
Established?
• Migration is affected not only by food supply, but
also by wind and oceans currents. These make
some routes and locations easier to reach. While
many birds migrate from northern breeding areas in
the summer, to southern wintering grounds (mainly
because there is more land near the northern pole
than the southern), there are many other migration
patterns. Some birds migrate horizontally, to enjoy
the milder coastal climates in winter. Other birds
migrate in terms of altitude; moving higher up a
mountain in summer, and wintering on the lowlands.
Migration Fun Facts • The arctic tern flies a phenomenal round trip that can be as long as
20,000 miles per year, from the Arctic to the Antarctic and back. The sandhill and whooping cranes are both capable of migrating as far as 2,500 miles per year, and the barn swallow more than 6,000 miles.
• How do they keep going? Some birds store a special, high-energy fat before the trip. Soaring raptors, for example, may not eat for several weeks as they migrate. Other species eat along their migration routes.
• How high can they fly? Higher than Mt. Everest. Bar-headed geese have been recorded flying across the Himalayas at 29,000 feet. From radar studies, scientists know that birds can change altitudes to find the best wind conditions. To fight a headwind, most birds stay low, where ridges, trees and buildings slow the wind. To ride a tailwind, they get up high where the wind is as fast as possible.
How Do I Get Started? Go with someone who has already been doing it for a
while. Consider joining one of the local organizations such as the Audubon Society.
Many good book and nature stores have an excellent selection of books, videos, magazines and tapes on bird watching (Wild Birds Unlimited).
Birding is also a popular Internet subject.
Learn to identify common local species using your field guide and audio tapes. Consider putting a bird feeder and/or bird attracting native plants around your home.
Try to visit as many different habitat types as you possibly can. Many state and national parks and forests are great places to go bird watching.
Viewing Tips
Viewing Tips - Follow these tips from experienced behavior watchers to witness wildlife without startling them or sapping their energy. It's a feeling you'll always remember.
Fade Into the Woodwork
Wear natural colors and unscented lotions. Some birds can smell! (turkey vulture)
Remove glasses that glint.
Walk softly so as not to snap twigs or trample wildflowers.
Crouch behind boulders or vegetation to blend your figure or break up your outline.
Where Do I Look For Birds?
Which Field Guide Should I Buy? A practical guide will have the picture of the bird,
the verbal description, and the range map all on facing pages.
A Texas birder needs a guide that covers bird species occurring throughout the United States. East meets west and north meets south in our great centrally located state.
The National Geographic Society's Field Guide to the Birds of North America is a good one, as are the Sibley Guide, Peterson Guides and the Golden Guide.
Binoculars These will help bring the birds closer to you optically so you can
better discern a bird's field marks, plumage pattern and color, as
well as subtleties of behavior.
While good optics can be expensive, the choice of brand is very
individual. A good guideline is to buy the best optics you can afford. If you are a beginner, start with a cheaper model and graduate to a more expensive model as your skills increase.
Remember, before purchasing an expensive pair, it's important to try them out yourself to see which size, weight, eye relief, field of view, and light-gathering abilities are best for you.

What Are All Those Numbers?!?
Binoculars have a set of numbers on them referring to their magnification power and the size of their objective lens. These numbers are expressed as a formula such as 7 X 35, 7-15 X 30, 8 x 30, 8 x 42 or 10 x 42 are good binoculars for birdwatching.
The first number refers to the power or magnification. If this number is hyphenated it means that the binoculars are capable of a range of magnifications. In the example used above the 7-15 means that the binocular is capable of zooming between 7 and 15 power. Binoculars over 10 power may be difficult to hold steady enough to see the image clearly. Often these binoculars have provisions for mounting on a tripod. With a pair of either 7 × 50 or 7 × 35 binoculars, for example, things 1000 feet away would appear as large as they would if the viewer were standing (1000 divided by 7 = ) 143 feet away.
Aperture
The second number represents the aperture or the size of the objective lens in millimeters. The larger the objective lens the more light it allows into the binocular and the brighter and clearer the image will be. Unfortunately, as objective lenses get larger, the optics get heavier and more uncomfortable to hold.
Eye Relief
Eye relief is the maximum distance in millimeters that your eyes can be away from the eyepieces and still see the whole picture. Normal binocular eye relief ranges from 9 to 13 mm. This distance works well for folks with good eyesight.
Most glass wearers need eye relief over 13 mm. Binocular manufacturers try to provide this relief through the use of rubber eyecups that can be rolled down. Often this is not enough! Some binoculars are constructed with extended eye relief for glass wearers. Many manufacturers add the letter AB@ the description of binoculars with long eye relief.
How to Use Binoculars
Find the subject with your unaided eyes.
Bring the eyepieces just under your eyes.
Sight the subject over the tops of the eyepieces.
Slowly bring the binoculars to your eyes.
Notebook Buy yourself a high quality, compact notebook that fits easily in a vest
pocket, book pouch, or backpack.
Carry it with you at all times in the field, along with a waterproof pen.
Keep good field notes, recording interesting observations as they occur. Make this a habit. Always record the time of year, time of day, weather conditions, and place (part of the state with a short description of habitat, vegetation type and geology if you know it).
Don't ever try to commit your observations to memory. Better to take detailed notes on plumage, shape, size, behavior, or any confusing observations. Often what you think is an unimportant detail turns out to be the key element to properly
identifying a species.
Don't wait to "bird" your field guide when you get home at the end
of the day.
Making your own sketches with pertinent comments can also be helpful.
Start a Life List
Keep a Texas bird list, as well. 614 different bird species have officially been accepted by the Texas Rare Birds Committee.
The list gets even larger as you bird the entire state at different times of year.
Then, put your lists on computer if you have one.
I am ready to
watch some
birds, so where
do I start?
Birding Ethics Do not to disturb either the birds or their habitat. Walk softly on the
land.
Stay on established pathways and keep motor vehicles on established roads and parking areas.
Avoid harassment; don't disturb birds that are nesting or their nesting areas. Do not handle eggs or young or stay too long at a working nest.
Don't over-use playback tapes or screech owl recordings to call birds in.
Don't trespass on private property.
Avoid "tree-whacking" to arouse cavity dwellers.
Divide larger groups of people into smaller, more manageable numbers.
Support local and national bird conservation organizations.
Support the Texas Parks and Wildlife Nongame and Threatened and Endangered Species fund.
Support the National Audubon Society and Texas Nature Conservancy.

Start In Your Own Backyard! Food
Bird feeders & plants around your yard that offer fruits, seeds and habitat .
Black oil sunflower seed - To attract a diverse group of birds to your feeder, including chickadees, nuthatches, finches, cardinals and jays.
Suet (wintertime)- To attract insect-eating birds such as woodpeckers, chickadees and nuthatches.
Peanuts – Blue jays!
Add plants to add to your landscape!
Things To Remember About Feeders Birds need an escape route, so make sure you place the feeder near shrubs or
evergreen trees so they can make a quick get-away. Woody plants with thorns are helpful to birds because they provide refuge from predators such as house cats. This can also help keep the feeders out of the rain and food dry.
Keep your feeders clean to prevent diseases and deter pests. Disinfect occasionally with one part chlorine bleach and nine parts lukewarm water and dry thoroughly before refilling.
Once you start to provide food for birds, continue throughout the cold season. It's best to provide only one type of food per feeder. Birds feeding at feeders with mixed seed discard the seeds they do not want while selecting their favorites.
Do not feed birds spoiled leftovers, salty snack foods or sugary cereals.

Shelter
Shelter can be provided in many ways, including bird houses or nest boxes (beginning of the year)
Choosing a bird house will depend on your goal. Do you want a great looking garden ornament or are you looking to attract a certain type of bird? One other way to provide shelter is with the types of trees and shrubs in your yard.
Things To Remember About Birdhouses
Face the entrance hole to the north or east to
prevent the birds from overheating if summers
are hot in your area.
Mount bird houses on poles or posts rather than
nailing them to trees or hanging them from
limbs, making them less vulnerable to predators.
Don't put bird houses next to bird feeders.
Clean your bird house yearly.
Start In Your Own Backyard Water
Water can make a difference to the number of birds visiting your feeders. If birds must fly long distances to find water in the winter, they may choose to stay near their water source rather than coming back to your feeder.
Circulating or moving water is more attractive to birds than stagnant water.
The easiest way to provide water is by maintaining your bird bath year round.
