This week we take a look at (and listen to) the ivory-billed woodpecker and its close relative, the imperial woodpecker. Is it alive? Is it extinct?

Show transcript: A lot of people who aren’t otherwise into birds have heard of the ivory-billed woodpecker because of the 2004 and 2005 sightings, which were widely reported in the press. Before we talk about that, let’s get some background and discuss the bird itself. There are actually two ivory-billed woodpeckers, the American bird and the Cuban. Originally they were listed as separate species. They’re big birds, glossy black in color with white markings. The male has a red crest with a black stripe up the front while the female’s crest is all black. They need vast areas of undisturbed forest to thrive, something that’s in short supply these days. By the early 20th century, the Cuban ivory-billed woodpecker was already restricted to pine forests in the northeast of Cuba due to habitat loss. By the late 1940s it was rare. In 1956 some small populations were still around, but while conservation was urged, the Cuban revolution in 1959 stopped any conservation progress. The last positive sighting was in 1989. The Cuban government designated the area of its sighting as protected, but no one’s seen one since. Another bird, the imperial woodpecker, is the largest woodpecker in the world. It lives in Mexico and is over two feet long, or 61 cm, with a wingspan of probably around three feet, or about a meter—maybe more. The female’s crest curls forward. Until the early 1950s, the imperial woodpecker was reasonably widespread although people did shoot it sometimes. Then companies started logging in the imperial woodpecker’s territory. One old man remembered a forester telling locals that the birds destroyed trees and even gave them poison to spread on feeding sites. But the imperial woodpecker only feeds and nests in trees that are already dead or dying. It was never a threat to healthy trees. The last confirmed sighting of the imperial woodpecker was in 1956. No photographs of a living imperial woodpecker exist. Then researcher Martjan Lammertink found mention in a 1962 letter of video taken of a bird in 1956 by dentist and amateur birder William Rhein. Rhein had become reclusive in his old age and moved with no forwarding address at least once, but Lammertink managed to track Rhein down in 1997, when he was in his late 80s. Rhein died in 1999. Once Lammertink found him, Rhein produced 85 seconds of 16 mm movie footage he’d taken back in the 1950s, which showed a female imperial woodpecker hitching up a tree and flying away. From those 85 seconds, researchers learned a lot about the bird, helped by a 2010 expedition that pinpointed the exact location where the footage was shot. There have been numerous sightings of imperial woodpeckers since the 1950s, but the list is discouraging. The sightings taper off slowly in different areas over the decades. The most recent was 2005, but it hasn’t been verified and no photographs were taken. These days, the areas where imperial woodpeckers once lived are now dangerous to explore due to drug cartels, which grow marijuana and opium poppies in remote clearings with armed guards. You probably won’t be surprised to hear that the American ivory-billed woodpecker’s story is pretty much the same as the others. It’s an impressive bird, as much as 21 inches long, or 53 cm, with a two and a half foot wingspan, or 76 cm.
