Duration: 8 min 48 s
Description: The National Oceanic and Atmospheric Administration (NOAA) operates underwater microphone arrays throughout the world's oceans, going them th ability to listen to goings-on below the surface. Many sounds capture by those hydrophones they recognize--but some, they don't. In this episode I'll share some of these mysterious sounds with you. What do YOU think they are?

So interesting. I do love the name of this one :) Great episode Steve!

Recorded in Sierra Valley, California, on June28, 2014, during the Nature Sounds Society annual meeting.
Recorded with a Sony PCM-M10 and AT2022 mic with Felmicamps preamp.

Domestic argument, or something along those lines, amongst various baboons, recorded at roughly 2am in Stanley and Livingstone Private Game Reserve, Zimbabwe.

I am not entirely sure what is going on here, but something upset the baboons at first, possibly a nearby predator, but it's anyone's guess. It then appears to just drag on for a while with baboons in various different trees giving off alarm calls, and some making a call that appears to be intended to calm down the others (but I will have to verify this later on). 

All in all something must have upset them because normally these kind of eruptions of vocalisations only last for a short duration, whereas this event continued for near 10 minutes. Whether it was just a whole lot of noise over nothing and all the neighbours getting involved out of irritation, or something else, I will probably never know for sure.

Episode 279–Mystery Sounds

On a bright and sunny mid-March day, the pond is warming up with sounds.
This is my most detailed recording of Corixa punctata (aka Lesser water boatman) to date.

Can the Lesser and Greater families be told apart through sound alone? Please let me know. What seems clear is that it is possible to discern between some lesser varieties, as demonstrated by Marco Presente in this recording:

**The sounds get really loud and right at the peak of the Fletcher-Munson curve so please take care of your ears**

Species: Lesser Water Boatman (Corixa punctata)
Location: Middle Spernal, Warwickshire, UK
Date and time: 19 March 2025, 13h30
Habitat: Freshwater pond, wetland

Gear
Aquarian Audio A5s, Zoom F3

Water Boatmen

Recorded on four channels nearby laggon under  Svínafellsjökull glacier south of Vatnajökull glacier in Iceland.
Two microphones are recording the soundscape above the  glacier lagoon and two hydrophones are placed in the lagoon.

A lovely variety of birds (plus red squirrels) greet the morning with song and drumming.  Singers include American Robin, White-breasted Nuthatch, Dark-eyed Junco, Common Raven, Hermit Thrush, Audubon's Warbler and others.  Drummer was a Three-toed Woodpecker.  Recorded with a Sony PCM-M10 with EM-172 capsules.

I had come to Kyambura Gorge in Uganda's Queen Elizabeth National Park to observe chimpanzees in their natural habitat. Along the way I stopped to record the wonderful soundscape of this rich ecosystem, made all the more interesting by the incredible acoustics of the gorge.

A SYMPHONY OF LOONS - track sample from LOON LAKE, available here: http://store.musicofnature.com/products/pure-nature/loon-lake

Recorded in early May at dusk, in Algonquin National Park, Ontario (2011).
Microphone: quasi-binaual SASS (Stereo Ambient Sampling System) modified for use with Sennheiser MKH20 microphones.

LISTEN AS LOONS call from near and far, their wails, yodels, and tremolos echoing across still waters against a backdrop of distant spring peepers. 

Shortly after dusk, numerous pairs of loons begin sounding off, communicating to each other their territo-rial boundaries. Their wails, yodels, and tremolos echo from near and far across the still waters, against a continuous backdrop of distant Spring Peepers. The wildly undulating yodel is the male loon’s territorial call. Wails that sound like the lonesome howls of wolves are used as contact calls. The tremolo calls, which signify arousal, sound like hysterical laughter and give rise to the term “crazy as a loon.” 

The evening performance of loons in early May is unforgettable – a truly symbolic soundscape of the northern lake country wilderness. In this unique “long-form” recording, we share our best loon recordings from Algonquin National Park, Ontario, gathered during the evenings of May 3 and 4 in 2011 (at times, you may also notice the cackles of Wood Frogs, the distant hoots of a Barred Owl, the quacks of a lone Black Duck, and the squeals of Ring-billed Gulls).

Additional Notes: My expedition with Bob McGuire to Algonquin National Park started out badly. We paddled to the north end of a large lake and set up camp on an island. The wind was strong and cold, with whitecaps visible not far offshore – impossible recording conditions, or so it seemed. But when the sun finally set, as if by magic, the wind lightened and then disappeared altogether, just as the loons began their evening rhapsody. The sudden calm took us completely by surprise and we literally jumped into our canoes, frantically (and rather unsuccessfully) trying to maneuver into good positions for recording. Although the wind grew brisk during each following day, we were fortunate to have two more calm evenings before we had to part. I really love the northern lake country wilderness and our journey to Algonquin Park to record loons is one I’ll treasure for the rest of my life.

EP 007 "Keeping the Path Clear," - Joey Weinert

I photograph, record, and write about the natural world. I see, I listen, I write. I fundamentally believe that curiosity can save the world—so I publish stories to make people curious. Ultimately, curiosity leads to discovery, discovery leads to knowledge, knowledge leads to insight, and insight leads to understanding. Please enjoy!
