The peregrine falcon nearly vanished. In the decades after World War II, pesticides like DDT worked their way up the food chain, thinning the birds' eggshells until they cracked before chicks could hatch. By the 1960s, the species had disappeared entirely from the eastern United States. It was a textbook case of human carelessness — and also, improbably, of human recovery.
Rachel Carson's "Silent Spring" in 1962 changed everything. The book sparked a movement to ban the worst offenders, and peregrine falcons began their slow climb back. Today, these slate-blue raptors with their 200-mph hunting dives are found across the planet again. Their comeback is one of conservation's clearest wins.
But that recovery is now under threat — not from pesticides this time, but from a proposal that sounds bureaucratic and technical until you understand what it means. Canada and the United States want to lower international trade protections for peregrine falcons, arguing that the species is now stable enough to warrant fewer restrictions on buying and selling them.

"Peregrine falcons are still vulnerable, and we can't afford to let our guard down," she says. "Reducing trade protections could undo decades of hard-won progress in bringing this iconic species back from the brink of extinction."
The concern isn't abstract. Weakened trade rules create openings for poaching and trafficking. Peregrine falcons are prized in falconry, particularly in the Middle East and Asia, and the birds command high prices on black markets. Even if most of the world's peregrine falcon population continues to recover, illegal capture of birds from recovering populations in vulnerable regions could slow or reverse local gains. The species still faces real pressure from habitat loss, climate change, and lingering pesticide contamination in some areas.
The proposal will be debated at the next meeting of CITES — the Convention on International Trade in Endangered Species — where dozens of countries will weigh the scientific evidence. The timing matters. Peregrine falcons have recovered in many parts of the world, but "recovered" doesn't mean "invulnerable." It means we finally stopped poisoning them. Removing the guardrails now would test whether that recovery can actually hold.
