This Live Stream Lets You Eavesdrop on Endangered Killer Whales' Conversations

Southern resident killer whales, which are usually found off the coasts of Washington, Oregon, and British Columbia, are an endangered species. If you're lucky, though, you might be able to hear a pod of the killer whales chattering away from the comfort of your own home. A website spotted by The Kansas City Star lets you live stream the calls of killer whales from your phone or laptop. Dubbed Orcasound, it uses hydrophones (underwater microphones) to pick up oceanic sounds from two areas off the coast of Washington.

On the website, listeners can choose between the two locations. One is the Orcasound Lab in Haro Strait, which is situated off the coast of Washington's San Juan Islands—the "summertime habitat" of this specific ecotype of whale, according to the website. The other location is Bush Point at the entrance to Puget Sound, where the whales pass through about once a month in search of salmon. However, that hydrophone is currently being repaired.

So what do orcas sound like? They're loud, and they do a whole lot of whistling, whining, and clicking. You can hear a snippet of what that sounds like in a four-minute podcast uploaded to the Orcasound site.

There’s no guarantee you’ll hear an orca, though. "Mostly you'll hear ships," the website notes, but there's also a chance you'll hear humpbacks in the fall and male harbor seals in the summer.

The live stream isn't just for educational purposes. It also serves as a citizen science project to help researchers continue their studies of southern resident killer whales, which are in danger of starvation as Chinook salmon, their main food source, die off.

The makers of Orcasound are urging listeners to email ihearsomething@orcasound.net anytime they hear killer whales or "other interesting sounds." They can also log their observations in a shared Google spreadsheet. Eventually, developers of the site hope to roll out a button that listeners can click when they hear a whale, to make the process easier for people to get involved.
