I. The Monopoly

In 1792, Congress exercised its constitutional power to “establish Post Offices and Post Roads” and created something more durable than a postal service. It created a monopoly, and it defended that monopoly with criminal law.¹ The Private Express Statutes, as the body of law is known, consist of the criminal provisions at 18 U.S.C. §§ 1693 through 1696 and the civil provisions at 39 U.S.C. §§ 601 through 606, implemented through Parts 310 and 320 of Title 39 of the Code of Federal Regulations.² The statutes restrict the carriage and delivery of letter mail by private organizations. They cover letters. They do not cover parcels or periodicals. The distinction matters, and the pigeons, as will be shown, fall on the wrong side of it.

The operative criminal provision is 18 U.S.C. § 1696(a): “Whoever establishes any private express for the conveyance of letters or packets, or in any manner causes or provides for the conveyance of the same by regular trips or at stated periods over any post route which is or may be established by law, or from any city, town, or place to any other city, town, or place, between which the mail is regularly carried, shall be fined not more than $500 or imprisoned not more than six months, or both.”³ A companion provision reaches anyone having charge of a conveyance operating by land, air, or water who regularly performs trips at stated periods on any post route and carries letters otherwise than in the mail.⁴ Subsection (b) punishes whoever transmits a letter by private express or other unlawful means. A federal court summarized the scheme plainly: the statutes “essentially prohibit the delivery of letters by private entities across postal service routes without United States postage, and for compensation, unless the action falls within a limited range of exceptions.”⁵

This investigation applies that framework to the homing pigeon. The application is straightforward. The facts are not in dispute. The conclusions follow from the statute’s own words, which is more than can be said for most conclusions drawn from statutes.

II. The Carrier

The homing pigeon is a variety of domestic pigeon, Columba livia domestica, selectively bred for its ability to find its way home over extremely long distances. It is also called the mail pigeon. It is also called the messenger. Colloquially, it is called the homer. The names are not our characterization. They are the bird’s.⁶

Its performance specifications would satisfy any logistics manager. Homing pigeons average approximately 97 kilometers per hour, about sixty miles per hour, over moderate distances of 965 kilometers, about six hundred miles. Speeds of up to 160 kilometers per hour, about one hundred miles per hour, have been observed in top racers over short distances. Flights as long as 1,800 kilometers, about eleven hundred miles, have been recorded in competitive racing.⁷ Until the introduction of the telephone, homing pigeons were used commercially to deliver communication. The practice was called pigeon post. The term appears in the historical record without irony and without a permit number.

The scale of the historical operation is documented. During the siege of Paris in the Franco-Prussian War, an estimated eight hundred homing pigeons were used to send upward of forty thousand messages.⁸ Each message was a tangible communication directed to a specific addressee, recorded on a physical medium, and carried in a capsule. Under the Private Express Statutes, the relevant question is whether a “letter or packet” was conveyed. A message in a leg capsule is either a letter or a packet. There is no third category. The statute’s drafters, writing in 1792 and 1948, did not exempt capsules.

III. The Precedent

On January 11, 1844, Lysander Spooner wrote to the Postmaster General of the United States and announced that he proposed to establish a letter mail from Boston to Baltimore, adding that he would remain in Boston, ready at any time to answer any suit.⁹ His American Letter Mail Company offered five-cent stamps against the Post Office’s rates, which ran as high as eighteen and three-quarter cents for a letter from Boston to New York. The company operated offices in Boston, New York, Philadelphia, and Baltimore, with daily service between the cities and twice-daily service between New York and Philadelphia.¹⁰

The government responded the way monopolists respond. Agents were arrested, including one taken into custody as he boarded a train at Baltimore, and convicted of infringing the federal monopoly. Spooner published a pamphlet titled The Unconstitutionality of the Laws of Congress Prohibiting Private Mails, arguing that the constitutional power to establish post offices was permissive rather than exclusive. The prosecutions continued until he abandoned the enterprise within the year.¹¹ Congress subsequently cut its rates, and in 1851 it strengthened the monopoly statutes and forced the remaining private carriers out of business. It was not poor service or outrageous prices that closed Spooner’s company. It was, literally, an act of Congress.¹²

The precedent is therefore established: the United States government has prosecuted a man for carrying letters between cities at five cents apiece without its permission. The question this investigation poses is what the government did next.

IV. The Government’s Own Express

What the government did next was operate the largest private express in the history of the republic, using carriers that weighed approximately one pound each and required no fuel.

The United States Army Signal Corps used six hundred pigeons in France during the First World War.¹³ One of them, a hen named Cher Ami, delivered twelve important messages during the Battle of Verdun. On October 4, 1918, during the Meuse-Argonne offensive, Major Charles Whittlesey’s trapped battalion of the 77th Infantry Division, the “Lost Battalion,” dispatched its last pigeon with a message reading, in substance: our own artillery is dropping a barrage directly on us, for heaven’s sake stop it.¹⁴ Cher Ami flew approximately twenty-five miles to division headquarters in about twenty-five minutes, despite having been shot through the breast, blinded in one eye, and having a leg hanging by a tendon with the message capsule still attached. The barrage stopped. One hundred ninety-four soldiers lived. France awarded the bird the Croix de Guerre with Palm. General Pershing personally saw Cher Ami off on the voyage home. The pigeon died on June 13, 1919, and its preserved body is on display at the Smithsonian Institution.¹⁵

The Navy maintained twelve pigeon stations in France with a total inventory of 1,508 pigeons. Eight hundred twenty-nine birds flew in 10,995 wartime aircraft patrols, carrying messages clear of propellers and airframes; 219 messages were delivered successfully.¹⁶ In the Second World War, the scale expanded: some 54,000 war pigeons were used, and an estimated ninety percent of the messages they carried were received.¹⁷

The outstanding individual flight of that war belonged to G.I. Joe, Pigeon USA43SC6390 of the United States Army Pigeon Service. On October 18, 1943, British forces captured the Italian village of Calvi Vecchia ahead of schedule but could not radio the airfield to cancel a planned bombing. G.I. Joe was dispatched as a last resort and flew twenty miles in twenty minutes, arriving as the bombers prepared for takeoff. At least one hundred Allied soldiers, and countless civilians, were saved from their own air force.¹⁸ On November 4, 1946, G.I. Joe received the Dickin Medal at the Tower of London, the twenty-ninth recipient and the first non-British one, with a citation crediting “the most outstanding flight made by a United States Army homing pigeon in World War II.”¹⁹ The People’s Dispensary for Sick Animals, which administers the Dickin Medal, records at least one hundred Allied soldiers and countless civilians saved by that single delivery.²⁰

The Dickin Medal, instituted in 1943 by PDSA founder Maria Dickin and known as the animals’ Victoria Cross, was awarded fifty-four times between 1943 and 1949. Thirty-two of the recipients were pigeons. Eighteen were dogs. Three were horses. One was a cat.²¹ The pigeons hold the plurality. They earned it carrying letters.

The United States prosecuted Lysander Spooner for establishing a private express with offices in four cities. It then established a private express with lofts across two continents, staffed by fifty-four thousand carriers, operating by regular dispatch on military timetables, between places between which the mail was regularly carried. No prosecution followed. The monopoly, it turns out, had an owner, and the owner was exempt in the way that owners are.

V. The Urgency Test

In 1979, the Postal Service suspended the Private Express Statutes for “extremely urgent” letters, a suspension that gave rise to the express delivery industry as Americans know it, including Federal Express and UPS express services.²² The suspension sets two tests. Under the first, a letter dispatched within fifty miles of its destination before noon must be delivered within six hours or by the close of the addressee’s normal business day; dispatched after noon, by ten the next business morning. Beyond fifty miles, delivery must be completed within twelve hours or by noon of the next business day.²³ Under the second test, a letter is conclusively presumed extremely urgent if the amount paid for its private carriage is at least three dollars or twice the applicable First-Class rate, whichever is greater.²⁴

Apply the first test to the documented flights. G.I. Joe covered twenty miles in twenty minutes. The regulation allows six hours. The pigeon satisfied the Postal Service’s urgency standard by a factor of eighteen, and it did so while the alternative was the bombing of the addressees. Cher Ami’s twenty-five miles in approximately twenty-five minutes satisfies the standard by a factor of fourteen. These were, by the Postal Service’s own definition, extremely urgent letters. They were also the only letters in the history of the suspension to be delivered under artillery fire, which the regulation does not address.

The suspension, however, imposes conditions beyond speed. The sender must prominently mark the cover with the words “Extremely Urgent” or “Private Carriage Authorized by Postal Regulations (39 CFR 320.6),” show the name and address of the carrier and the addressee, and keep records sufficient to demonstrate timely delivery, available for inspection at the Postal Service’s request.²⁵ No pigeon has ever marked its capsule. No pigeon has ever displayed the carrier’s name and address. No loft has ever produced records for a Postal Service inspector. The birds that best satisfied the time limits satisfied none of the paperwork, and the paperwork is the part the Postal Service actually reads.

VI. The Compensation Question

Section 1696(c) provides that the chapter shall not prohibit “the conveyance or transmission of letters or packets by private hands without compensation, or by special messenger employed for the particular occasion only,” adding that when more than twenty-five letters or packets are conveyed by such special messenger, the requirements of 39 U.S.C. § 601 must be observed as to each piece.³ The pigeons’ defenders, if any existed, would invoke the “without compensation” clause. The clause does not survive contact with the facts.

War pigeons received housing, feed, veterinary care, training, and transport to theaters of war on two continents. Racing pigeons receive purpose-built lofts, specialized nutrition, and bloodlines managed with the care of thoroughbred studs. In 2020, a Chinese buyer paid a record £1.3 million for a champion racing pigeon from Belgium.²⁶ A carrier compensated in grain, housing, veterinary care, and, at the top of the market, seven-figure transfer fees is not an uncompensated volunteer. It is a compensated professional whose compensation happens to be denominated in seed.

Nor does the “special messenger employed for the particular occasion only” clause avail them. Competitive pigeon racing is an organized sport conducted as scheduled events over measured courses, a tradition running continuously since the first long-distance race in Belgium in 1818.²⁷ Scheduled competitions are the opposite of a particular occasion. They are, in the statute’s own phrase, regular trips at stated periods, wearing a stopwatch.

VII. The Modern Violations

The violations are not historical. The racing industry continues to breed, train, and fly homing pigeons over measured courses between cities where the mail is regularly carried, and the birds continue to carry the leg bands and identification of organized competition. The military lofts closed, but the civilian express never did. It simply stopped carrying military dispatches and started carrying race timings, which are packets by any definition that does not require the contents to be interesting.

Foreign governments, at least, have recognized the regulatory exposure, though they have charged the wrong offense. In May 2023, police in Mumbai captured a pigeon near the port with two rings on its legs and markings resembling Chinese script on its wings. The bird was detained for eight months at the city’s Bai Sakarbai Dinshaw Petit Hospital for Animals while police investigated suspected espionage. It was released on January 30, 2024, after the inquiry determined it was an open-water racing bird from Taiwan that had gone astray, with formal permission secured through the intervention of People for the Ethical Treatment of Animals.²⁸ It was not the first such detention: Indian authorities held a pigeon under armed guard in 2010 after finding a Pakistani phone number stamped on its body, took another into custody in 2016 over a threatening message to the prime minister, and released a third in Kashmir in 2020 after determining it belonged to a Pakistani fisherman.²⁹

Eight months of detention, a hospital ward, a formal police inquiry, an international animal-welfare intervention, and at no point did any authority ask the only question the statutes pose: where is the postage. The espionage investigation closed for lack of evidence. The postal violation was never opened. It never is.

VIII. Penalty Exposure

The exposure, if the statutes mean what they say, is considerable. Section 1696(a) punishes the establishment of a private express with a fine of not more than $500 or imprisonment of not more than six months, or both, per offense. Section 1696(b) punishes the transmission of letters by private express with fines under Title 18, per letter.

Consider only the documented American military transmissions: 219 messages delivered by Navy pigeons across 10,995 patrols, twelve messages delivered by Cher Ami at Verdun, the Lost Battalion message of October 4, 1918, and G.I. Joe’s flight of October 18, 1943. That is 233 documented transmissions of letters or packets by private express, each a separate violation of § 1696(b). The 600-pigeon Signal Corps operation in France and the 54,000-pigeon operation of the Second World War each constitute the establishment of a private express under § 1696(a), with the per-carrier arithmetic left as an exercise for the United States Attorney.

The forty thousand messages of the Paris siege are excluded from this computation. They fall outside American jurisdiction, and this investigation respects venue even when the pigeons did not respect borders.

IX. Conclusion

The Private Express Statutes are real. They were enacted in 1792, they remain in force, and in 1986 a federal court confirmed that they prohibit the private delivery of letters without United States postage except within narrow exceptions. The homing pigeon is real. It flies sixty miles per hour over six hundred miles, it was known as the mail pigeon until the telephone displaced it, and its message capsule is either a letter or a packet. Lysander Spooner is real. The government prosecuted him for carrying letters at five cents apiece. The government’s own pigeon express is real. Six hundred birds in France, fifty-four thousand in the Second World War, 219 Navy messages, twelve at Verdun, one that saved 194 soldiers, one that saved a village in twenty minutes. Thirty-two Dickin Medals.

The urgency suspension is real. G.I. Joe satisfied it by a factor of eighteen. The marking requirement is real. No pigeon has ever complied with it. The compensation exception is real. The pigeons are compensated in grain, housing, and veterinary care, and at auction, in millions. The modern violations are real. The racing industry flies scheduled competitions, and in 2023 a pigeon spent eight months in Indian police custody while the postal question went unasked.

No pigeon has ever affixed postage. No pigeon has ever marked its cover “Extremely Urgent.” No loft has ever produced records for a Postal Service inspector. The birds are not going to start. They have been carrying messages since before the Post Office Department existed, and their compliance department consists of a homing instinct and a willingness to fly through artillery fire.

The Postal Service should consider its options carefully. It has approximately one year of precedent suggesting the birds will not answer a subpoena.

Ergo.
