On my Costa Rica expedition I was reacquainted with howler monkey calls after first having heard them in the Amazon a few years prior. Longer version at https://youtu.be/emtVr3Mbjcg

Dawn in Costa Rica jungle - Howler monkey sounds

Costa Rica's rainforests are lively and active at night, even if it might not seem like it. A night walk in the jungle will reveal countless creatures going about their business - hunting or trying to avoid hunters, looking for food and sometimes searching for a mate.

Night in the jungles of Costa Rica

Needle - Clawed Galago Squeak

In the rainforest, each creature has its own little place in the frequency spectrum or time domain. The apparent chaos is random only when looked at (or listened to, rather) for very short durations. More details at https://youtu.be/E7byvKAJHGU

Costa Rica jungle atmosphere

Underwater sounds of freshwater shrimp munching (or, trying to munch) on hydrophones. Not clear whether it is the invasive 'Gammarus pulex' or the native 'Gammarus duebeni celticus' species.

FRESHWATER SHRIMP Munching

’Stridulation’, we find, is one of those beautifully descriptive words. Much like crickets or cicadas on solid ground, aquatic invertebrates produce an array of sounds by rubbing their body parts, know as stridulations. These together with the sounds of chewing, grazing, amphibian vocalisations and even plants oxygenating, create rich underwater soundscapes. In this extract you can mainly hear aquatic bug stridulations. But if you listen carefully with the help of headphones, you can also  make out faint munching and the odd low grunt (possibly from an amphibian such as a frog). You can also make out the breeze on the hydrophone cables, creating ripples on the water surface which presumably filter down underwater. And towards the end of the file, human sounds from children playing nearby.

Underwater STRIDULATIONS

Recorded after heavy rain in my tropical garden in Phetchabun Thailand. Track includes calls of different species of Frogs and Cicadas.

Frogs And Cicadas

Surprisingly, we still have plenty of winter thrushes still around, in April! and still no Swallows seen, despite the fact that we had one of the hottest Marches on record, no doubt followed by -5 at the start of April.. so they clearly new the cold snap wasn't over yet. 

Nice to hear them singing away, but mostly still subsong as apposed to their territorial breeding song, which they have no purpose to really sing just yet as they are not on territory.
