+
+Identification is Important
+
+
+Identifying waterfowl gives many hours of enjoyment to millions of
+people. This guide will help you recognize birds on the wing--it
+emphasizes their fall and winter plumage patterns as well as size,
+shape, and flight characteristics. It does not include local names.
+
+Recognizing the species of ducks and geese can be rewarding to
+birdwatchers and hunters--and the ducks.
+
+Hunters can contribute to their own sport by not firing at those species
+that are either protected or scarce, and needed as breeders to restore
+the flocks. It can add to their daily limit; when extra birds of certain
+species can be taken legally, hunters who know their ducks on the wing
+come out ahead.
+
+Knowing a mallard from a merganser has another side: gourmets prefer a
+corn-fed mallard to the fish duck.
+
+
+
+
+What to Look For
+
+
+Differences in size, shape, plumage patterns and colors, wing beat,
+flocking behavior, voice, and habitat--all help to distinguish one
+species from another.
+
+Flock maneuvers in the air are clues. Mallards, pintails, and wigeon
+form loose groups; teal and shovelers flash by in small, compact
+bunches; at a distance, canvasbacks shift from waving lines to temporary
+V's.
+
+Closer up, individual silhouettes are important. Variations of head
+shapes and sizes, lengths of wings and tails, and fat bodies or slim can
+be seen.
+
+Within shotgun range, color areas can be important. Light conditions
+might make them look different, but their size and location are positive
+keys. The sound of their wings can help as much as their calls. Flying
+goldeneyes make a whistling sound; wood ducks move with a swish;
+canvasbacks make a steady rushing sound. Not all ducks quack; many
+whistle, squeal, or grunt.
+
+Although not a hard and fast rule, different species tend to use
+different types of habitat. Puddle ducks like shallow marshes and creeks
+while divers prefer larger, deeper, and more open waters.
+
+
+
+
+Eclipse Plumage
+
+
+Most ducks shed their body feathers twice each year. Nearly all drakes
+lose their bright plumage after mating, and for a few weeks resemble
+females. This hen-like appearance is called the eclipse plumage. The
+return to breeding coloration varies in species and individuals of each
+species. Blue-winged teal and shovelers may retain the eclipse plumage
+until well into the winter.
+
+Wing feathers are shed only once a year; wing colors are always the
+same.
+
+
+
+
+Puddle Ducks
+
+
+Puddle ducks are typically birds of fresh, shallow marshes and rivers
+rather than of large lakes and bays. They are good divers, but usually
+feed by dabbling or tipping rather than submerging.
+
+The speculum, or colored wing patch, is generally iridescent and
+bright, and often a telltale field mark.
+
+Any duck feeding in croplands will likely be a puddle duck, for most of
+this group are sure-footed and can walk and run well on land. Their diet
+is mostly vegetable, and grain-fed mallards or pintails or
+acorn-fattened wood ducks are highly regarded as food.
+
+
+
+
+Mallard
+
+
+Length--24"
+Weight--2-3/4 lbs.
+
+The mallard is our most common duck, found in all flyways. The males are
+often called "greenheads." The main wintering area is the lower
+Mississippi basin, and along the gulf coast, but many stay as far north
+as open waters permits.
+
+Flocks often feed in early morning and late afternoon in nearby
+harvested fields, returning to marshes and creeks to spend the night.
+
+The flight is not particularly rapid. Hens have a loud _quack_; the
+drake's voice is a low-pitched _kwek-kwek_.
+
+
+
+
+Pintail
+
+
+Length--26"
+Weight--1-3/4 lbs.
+
+These ducks use all four flyways, but are most plentiful in the west.
+
+They are extremely graceful and fast fliers, fond of zig-zagging from
+great heights before leveling off to land.
+
+The long neck and tail make them appear longer than mallards, but in
+body size and weight they are smaller.
+
+They are agile on land and often feed in grain fields. The drakes
+whistle; the hens have a coarse _quack_.
+
+
+
+
+Gadwall
+
+
+Length--21"
+Weight--2 lbs.
+
+Gadwalls are most numerous in the Central Flyway, but not too common
+anywhere. They are often called "gray mallards" or "gray ducks." They
+are one of the earliest migrants, seldom facing cold weather.
+
+They are the only puddle ducks with a white speculum.
+
+Small, compact flocks fly swiftly, usually in a direct line. Wingbeats
+are rapid.
+
+Drakes whistle and _kack-kack_; hens _quack_ like a mallard, but softer.
+
+
+
+
+Wigeon
+
+
+Length--21"
+Weight--1-3/4 lbs.
+
+These are nervous birds, quick to take alarm. Their flight is fast,
+irregular, with many twists and turns. In a bunched flock, their
+movements have been compared to those of pigeons.
+
+When open water is handy, wigeons often raft up offshore until late
+afternoon when they move to marshes and ponds to feed.
+
+The white belly and forewing are very showy in the air. Drakes whistle;
+hens have a loud _kaow_ and a lower _qua-awk_.
+
+
+
+
+Shoveler
+
+
+Length--19-1/2"
+Weight--1-1/2 lbs.
+
+Shovelers, 'spoonbills' to many, are early migrants, moving out at the
+first frost. The largest numbers are in the Central and Pacific flyways.
+
+The usual flight is steady and direct. When startled, the small flocks
+twist and turn in the air like teal.
+
+They are not highly regarded as table birds, because one third of the
+usual diet is animal matter.
+
+Drakes call _woh-woh_ and _took-took_; the hen's _quack_ is feeble.
+
+
+
+
+Blue-Winged Teal
+
+
+Length--16"
+Weight--15 oz.
+
+Their small size and twisting turning flight gives the illusion of great
+speed. The small, compact flocks commonly fly low over the marshes, and
+often take the hunter by surprise.
+
+They are more vocal than most ducks--their high-pitched peeping and
+nasal quacking is commonly heard in spring and to a lesser extent in
+fall.
+
+These teal are among the first ducks to migrate each fall, and one of
+the last in the spring.
+
+
+
+
+Cinnamon Teal
+
+
+In the Pacific Flyway, cinnamon teal are far more common than
+blue-wings. The hens look alike and the habits of both species are
+similar.
+
+The pale blue forewing patch is the best field mark, as drakes are
+usually in eclipse until January or longer.
+
+Drakes have a whistling _peep_; hens utter a low _quack_.
+
+
+
+
+Green-Winged Teal
+
+
+Length--15 in.
+Weight--14 oz.
+
+Quite hardy--some birds stay as far north as open water is found.
+
+The smallest and one of the most common of our ducks. Their tiny size
+gives the impression of great speed, but mallards can fly faster. Their
+flight is often low, erratic, with the entire flock twisting and turning
+as one unit.
+
+They nest as far north as Alaska, and migrate in all four flyways. Early
+fall drakes are usually still in full eclipse plumage.
+
+Drakes whistle and twitter; hens have a slight _quack_.
+
+
+
+
+Wood Duck
+
+
+Length--18-1/2 in.
+Weight--1-1/2 lbs.
+
+Found in all flyways; most numerous in the Atlantic and Mississippi
+flyways and fewest in the Central.
+
+They are early migrants; most of them have left the northern States by
+mid-November.
+
+Frequents wooded streams and ponds; perches in trees. Flies through
+thick timber with speed and ease and often feeds on acorns, berries, and
+grapes on the forest floors.
+
+Flight is swift and direct; flocks are usually small.
+
+In the air, their wings make a rustling, swishing sound. Drakes call
+_hoo-w-ett_, often in flight; hens have a _cr-r-ek_ when frightened.
+
+
+
+
+Black Duck
+
+
+Length--24 in.
+Weight--2-3/4 lbs.
+
+A bird of the eastern States, primarily the Atlantic Flyway and, to a
+lesser extent, the Mississippi.
+
+Shy and wary, regarded as the wariest of all ducks.
+
+Often seen in company of mallards, but along the Atlantic coast
+frequents the salt marshes and ocean much more than mallards.
+
+Flight is swift, usually in small flocks.
+
+White wing lining in contrast to very dark body plumage is a good
+identification clue.
+
+The hen's _quack_ and the drake's _kwek-kwek_ are duplicates of the
+mallards.
+
+
+
+
+Diving Ducks
+
+
+Diving ducks frequent the larger, deeper lakes and rivers, and coastal
+bays and inlets.
+
+The colored wing patches of these birds lack the brilliance of the
+speculums of puddle ducks. Since many of them have short tails, their
+huge, paddle feet may be used as rudders in flight, and are often
+visible on flying birds. When launching into flight, most of this group
+patter along the water before becoming airborne.
+
+They feed by diving, often to considerable depths. To escape danger,
+they can travel great distances underwater, emerging only enough to show
+their head before submerging again.
+
+Their diets of fish, shellfish, mollusks, and aquatic plants make them
+second choice, as a group, for sportsmen. Canvasbacks and redheads
+fattened on eel grass or wild celery are notable exceptions.
+
+Since their wings are smaller in proportion to the size and weight of
+their bodies, they have a more rapid wingbeat than puddle ducks.
+
+
+
+
+Canvasback
+
+
+Length--22 in.
+Weight--3 lbs.
+
+Normally late to start south, canvasbacks migrate in lines and irregular
+V's.
+
+In feeding areas, compact flocks fly in indefinite formations. Their
+wingbeat is rapid and noisy; their speed is the swiftest of all our
+ducks.
+
+Feeding behavior is highly variable. In some areas they feed at night
+and spend the day rafted up in open waters; in other areas they feed
+inshore mornings and evenings.
+
+On the water, body size and head shape distinguish them from scaups and
+redheads.
+
+Drakes _croak_, _peep_, and _growl_; hens have a mallard-like _quack_.
+
+
+
+
+Redheads
+
+
+Length--20 in.
+Weight--2-1/2 lbs.
+
+Range coast to coast, with the largest numbers in the Central Flyway.
+Migratory flocks travel in V's; move in irregular formations over
+feeding areas. Often found associating with canvasback.
+
+In the air, they give the impression of always being in a hurry.
+
+Usually spend the day in large rafts in deep water; feed morning and
+evening in shallower sections.
+
+Drakes _purr_ and _meow_; hens have a loud _squak_, higher than a hen
+mallard's.
+
+
+
+
+Ringneck
+
+
+Length--17 in.
+Weight--2-1/2 lbs.
+
+Similar in appearance to scaups, but more often found in fresh marshes
+and wooded ponds. In flight, the dark wings are different from the
+white-edged wings of scaup.
+
+Faint brown ring on drake's neck never shows in the field; light bands
+at tip and base of bill are conspicuous.
+
+Fly as small flocks in open formation; often land without circling.
+Drakes _purr_; hens are usually silent.
+
+
+
+
+Scaup
+
+
+Greater--Length--18-1/2 in.
+ Weight--2 lbs.
+
+Lesser--Length--17 in.
+ Weight--1-7/8 lbs.
+
+Except for the wing marks, greater and lesser scaup appear nearly
+identical in the field.
+
+The light band near the trailing edges of the wings runs almost to the
+tip in the greater scaup, but only about half way in the lesser.
+
+Greater scaup prefer large open water areas; lesser scaup often use
+marshes and ponds.
+
+Both species migrate late, sometimes just before freezeup.
+
+Flock movements are rapid, often erratic, usually in compact groups.
+
+Hens are silent; drake lesser scaup _purr_; drake greater scaup have a
+discordant _scaup, scaup_.
+
+
+
+
+Goldeneye
+
+
+Common--Length--19 in.
+ Weight--2-1/4 lbs.
+
+Barrow's--Length--19 in.
+ Weight--2-3/4 lbs.
+
+These are active, strong-winged fliers moving singly or in small flocks,
+often high in the air. Distinctive wing-whistling sound in flight has
+earned the name of whistlers.
+
+Goldeneyes generally move south late in the season; most of them winter
+on coastal waters and the Great Lakes. Inland, they like rapids and fast
+water.
+
+Barrow's goldeneye, predominantly a Westerner, is less wary than the
+common goldeneye.
+
+Hens of both species are look-alikes.
+
+Drakes have a piercing _speer-speer_--hens a low _quack_. Both are
+usually quiet.
+
+
+
+
+Bufflehead
+
+
+Length--14-1/2 in.
+Weight--1 lb.
+
+Stragglers migrate south in mid-fall, but the largest numbers move just
+ahead of freezeup. Most flocks in feeding areas are small--5 or 6 birds,
+with more hens and immatures than adult drakes.
+
+Very small size, bold black and white color pattern, and low, swift
+flight are field marks. Unlike most divers, they can fly straight up
+from a watery takeoff.
+
+Largest concentrations are on both seacoasts and along the Gulf of
+Mexico. Inland, they will remain as far north as open water permits.
+
+Usually silent. Drakes _squeak_ and have a guttural note; hens _quack_
+weakly.
+
+
+
+
+Ruddy
+
+
+Length--15-1/2 in.
+Weight--1-1/3 lbs.
+
+The ruddy duck often dives or swims away from danger rather than flying.
+When flying, their small wings stroke so fast they resemble bumblebees.
+
+They are early to mid-fall migrants.
+
+Drakes often cock their tails upright at an angle, the only species to
+habitually do so.
+
+Both hens and drakes are silent in the fall.
+
+
+
+
+Red-Breasted Merganser
+
+
+Length--23 in.
+Weight--21-1/2 lbs.
+
+These birds winter most abundantly in coastal waters, including the Gulf
+of Mexico, and to a lesser extent, the Great Lakes.
+
+Their flight, strong and direct, is usually low over the water. They are
+difficult to distinguish in flight from the common merganser.
+
+Voice: Seldom heard.
+
+
+
+
+Common Merganser
+
+
+Length--25-1/2 in.
+Weight--2-1/2 lbs.
+
+This species is larger than the red-breasted merganser, and is one of
+the largest of our ducks. It is one of the last to migrate south, and is
+more common than the red-breasted merganser on inland waters.
+
+Flocks move in "follow the leader" style, low over the water.
+
+The only call seems to be a startled _croak_.
+
+
+
+
+Hooded Merganser
+
+
+Length--18 in.
+Weight--1-1/2 lbs.
+
+Often seen in pairs, or very small flocks. Short rapid wingstrokes
+create an impression of great speed.
+
+Winters in the inland waters of all coastal States; seldom goes to salt
+water.
+
+Voice: Seldom heard in fall.
+
+
+
+
+Whistling Ducks
+
+
+Length--18-19 in.
+Weight--1-3/4 lbs.
+
+The trailing legs and rounded wings of these slow flying ducks makes
+them look bigger than they are.
+
+Both species are primarily Mexican. In the U.S., the black-bellied is
+found only in south Texas and Louisiana. The fulvous also occurs there
+and in Florida with occasional stragglers further north along both
+coasts and the Mississippi Valley. The fulvous is the more common of the
+two species in the United States.
+
+Sexes are alike. Both species have shrill whistling calls.
+
+
+
+
+White-Winged Scoter
+
+
+Length--21-1/2 in.
+Weight--3-1/2 lbs.
+
+The three scoters on these two pages are sea ducks, wintering on open
+coastal waters. White-wings are among the heaviest and largest of all
+ducks.
+
+
+
+
+Surf Scoter
+
+
+Length--19-1/2 in.
+Weight--2 lbs.
+
+Like all scoters, these birds move along our coasts in loose flocks,
+stringing into irregular, wavy lines. Drakes can be distinguished from
+other scoters by two white patches on their head and the bright color of
+the bill.
+
+Flight is strong, direct, usually close to the waves.
+
+
+
+
+Black Scoter
+
+
+Length--19-1/2 in.
+Weight--2-1/2 lbs.
+
+In flight, drakes appear all black except for the flash of the slight
+gray underwing and the bright yellow swelling at the base of the upper
+bill.
+
+Scoters feed on mollusks, crabs, and some fish and very little
+vegetation. They are locally known as "coots."
+
+
+
+
+Common Eider
+
+
+Length--23-1/2 in.
+Weight--5 lbs.
+
+Thick-necked stocky birds, alternately flapping and sailing in flight;
+flocks string out in a line, close to the water. Occurs in the United
+States chiefly along New England coasts and occasionally south to New
+Jersey.
+
+Other eiders--king, spectacled and Stellar's--occur in Alaska and are
+not pictured in this guide. King eiders occasionally are found in north
+Atlantic coastal waters.
+
+
+
+
+Oldsquaw
+
+
+Length--20-1/2 in.
+Weight--2 lbs.
+
+A slim, brightly plumaged sea duck. Smaller than the scoters or eiders.
+
+Flight is swift and low with constantly changing flock formations.
+Ranges along both coasts and the Great Lakes.
+
+One of the most vocal of ducks; drakes have a loud pleasant _caloo,
+caloo_, constantly heard.
+
+
+
+
+Harlequin
+
+
+Length--17 in.
+Weight--1-1/2 lbs.
+
+Glossy slate-blue plumage enlivened by white stripes and spots give the
+adult male harlequin a striking appearance. The female resembles a small
+female scoter. At a distance, both sexes look black. Flight is swift,
+with abrupt turns. Flocks are small and compact. Ranges both coasts,
+north from New Jersey and San Francisco. Uncommon.
+
+
+
+
+Swans
+
+
+Trumpeter--Length--59 in.
+ Weight--28 lbs.
+
+Whistling--Length--52 in.
+ Weight--16 lbs.
+
+Once thought to be rare, trumpeter swans are slowly increasing in Alaska
+and on western refuges and parks.
+
+Whistling swans are common and increasing. They winter near Chesapeake
+Bay, San Francisco Bay, Puget Sound and Salton Sea. Occasionally found
+in fields.
+
+Both species are large with pure white plumage.
+
+
+
+
+Canada Geese
+
+
+Numerous and popular, Canada geese are often called "honkers." Includes
+several races varying in weight from 3 to over 12 pounds. All have black
+heads and necks, white cheeks, similar habitats and voices. Sexes are
+identical.
+
+
+
+
+Brant
+
+
+Length--24-25 in.
+Weight--3-1/4 - 3-3/4 lbs.
+
+These are sea geese, the blacks wintering south to Baja, California, in
+the Pacific. The Atlantic race winters from Virginia northward. Flight
+is swift, in irregular and changing flock patterns.
+
+
+
+
+Snow Geese
+
+
+Length--29-31 in.
+Weight--6-1/2 - 7-1/2 lbs.
+
+Two races of snow geese are recognized: greater snows along the Atlantic
+Coast, and lesser snows elsewhere on the continent. Blue geese are a
+color phase of the lesser snow.
+
+
+
+
+White-Fronted Geese
+
+
+Length--29 in.
+Weight--6-1/4 lbs.
+
+Migrates chiefly in the Central and Pacific flyways but also present in
+the Mississippi. Rare in the Atlantic Flyway. Appears brownish gray at a
+distance. Often called "specklebelly".
+
+Most distinctive characteristic of the V-shaped flocks is the high
+pitched call _kow-kow-kow-kow_.
+
+
+
+
+COMPARATIVE SIZES OF WATERFOWL
+
+
+All birds on these pages are drawn to the same scale.
+
+
+
+
+Wetlands Attract Wildlife
+
+
+There's more than just ducks in our marshes. Knowing and identifying
+other birds and animals add to the enjoyment of being in a blind.
+
+The same sources of food and shelter that draw waterfowl to ponds and
+marshes also attract other forms of wildlife.
+
+Protected species are sometimes more numerous than ducks or geese.
+
+Money from Duck Stamp sales is used exclusively to purchase wetlands,
+preserving areas for ducks, geese, and all wildlife for the enjoyment
+and pleasure of hunters and non-hunters alike.
+
+
+
+
+Administrative Waterfowl Flyways
+
+
+Waterfowl Flyways
+
+The term "flyway" has long been used to designate the migration routes
+of birds. For management purposes, four waterfowl flyways--Pacific,
+Central, Mississippi, and Atlantic--were established in the United
+States in 1948. To varying degrees the waterfowl populations using each
+of these flyways differ in abundance, species composition, migration
+pathways, and breeding ground origin. There are differences, also, in
+levels of shooting pressure and harvest.
+
+For the most part flyway boundaries follow State lines. However, the
+boundary between the Pacific and the Central flyway general follows the
+Continental Divide.
+
+There are some problems in matching waterfowl migration corridors with
+flyway boundaries because some species nest and winter in areas that do
+not occur along a north-south axis. These species cross flyway
+boundaries during migration. On balance, the present arrangement is
+useful in that it permits reasonable management of waterfowl. At some
+future time, it is possible that further rearrangement of boundaries may
+permit better management of the waterfowl resource.
+
+
+Flyway Councils
+
+In 1952, Flyway Councils were formed in each of the four flyways. The
+Council in each flyway is made up of representatives from the wildlife
+agencies of the States in that flyway--one representative from each
+State. The Councils study flyway problems, develop waterfowl management
+recommendations, and generally work closely with the U.S. Fish and
+Wildlife Service in implementing waterfowl management and research
+programs.

+Created in 1849, the Department of the Interior--America's Department of
+Natural Resources--is concerned with the management, conservation, and
+development of the Nation's water, fish, wildlife, mineral, forest, and
+park and recreational resources. It also has major responsibilities for
+Indian and Territorial affairs.
+
+As the Nation's principal conservation agency, the Department works to
+assure that nonrenewable resources are developed and used wisely, that
+park and recreational resources are conserved for the future, and that
+renewable resources make their full contribution to the progress,
+prosperity, and security of the United States--now and in the future.

+Creating the works from public domain print editions means that no
+one owns a United States copyright in these works, so the Foundation
+(and you!) can copy and distribute it in the United States without
+permission and without paying copyright royalties. Special rules,
+set forth in the General Terms of Use part of this license, apply to
+copying and distributing Project Gutenberg-tm electronic works to
+protect the PROJECT GUTENBERG-tm concept and trademark. Project
+Gutenberg is a registered trademark, and may not be used if you
+charge for the eBooks, unless you receive specific permission. If you
+do not charge anything for copies of this eBook, complying with the
+rules is very easy. You may use this eBook for nearly any purpose
+such as creation of derivative works, reports, performances and
+research. They may be modified and printed and given away--you may do
+practically ANYTHING with public domain eBooks. Redistribution is
+subject to the trademark license, especially commercial

+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by

+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, is critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at https://www.gutenberg.org/fundraising/pglaf.

+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit https://www.gutenberg.org/fundraising/donate
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card donations.

+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart was the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+Most people start at our Web site which has the main PG search facility:
+
+ https://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
