Wild Bird Acoustics

Over the years, I have become increasingly fascinated by one of natures greatest engineers, European Beaver. As a field recorder, I am naturally to drawn to wetlands. These rich habitats are often full of interesting bird species and offer rich recording opportunities. Here in Sweden, particularly within large areas on natural forest, you can find wetland habitats that have been created by European Beaver and these are often incredibly biodiverse locations. Taking a deep dive into one of these Beaver wetlands was something I had wanted to do for some time. Over the course of early 2025, I finally decided to try and uncover some of the secrets these remarkable habitats might hold. Within Tyresta National Park, there was one particularly pristine example of such habitat. This is a mature, well established wetland that owes its existence entirely to these remarkable mammals. I set out to actively explore this location, using a combination of recording methods. The results were amazing. The audio was breathtaking. The journey was worth the effort. In this episode, the season finale, I will share the resulting audio with listeners. I have no doubt I will be returning to such habitats in the future. There is a lot to uncover at these sites, which are a testament to a remarkable mammal, it's effect on the landscape and the species that benefit from the tireless work these animals do. We can learn a lot from nature...

In the latter half of September 2025, I travelled north to the tiny island of Hällögern, in the northern part of Sweden. On this occasion I would spend two weeks on the island during the peak period of autumn migration. The trip was carefully planned and over the course of a fortnight I managed to to a great deal of active field recording, whilst out looking at birds in the field. My focus was on monitoring and recording passage migrants moving southwards along the coastline, as well as any interesting resident species that might be present on this tiny island. I had a magical time on the island and a great deal of success, with regard to field recording.  In this episode, I share some very high quality audio with listener's of the podcast, all secured in this wonderfully quiet location in Northern Sweden.

Along the coast of Västerbotten, each autumn, a vast migration of birds takes place each year. In 2025, by means of passive recording, I was able to monitor this migration by placing a recorder in cover for two months. During this period, a wide range of species moved through this area. On some mornings, the migration was heavy. There were times when migrant species were moving through cover. past my recorder at close range. This project gave me a unique insight into what was taking place at the island during the months of August and September. It is during these two months when passage is heaviest. Some of the resulting audio was remarkable and lifted the lid on bird movements through the area. In this episode, I share and discuss the audio with listeners.

Wild Bird Acoustics brings you two sound magazines in this episode. As Autumn now stretches out in front of us, I thought this might be a good time to include the second installment of passively recorded audio from my listening station at Hällögern in Västrbotten. Podcast listener's will now be very familiar with this location, but this will be the first time I will share audio from the late autumn period at this site. In 2024, due of the aqquisition on a new SM Mini recorder for this site, I was able to passively record for a significantly longer period of time, which allowed me to collect audio all the way into mid November. I will share the results of that passive deployment with listeners in this sound magazine.
The second half of this episode concernes itself with field recording at Tyresta National Park in early May. Having recorded there extensively throughout early spring, it was wonderful to get out into the field and experience new sounds in the park in May, those of newly return summer migrants. It is during the late spring period that many breeding species return and reclaim breeding territories at this site and I was on hand to get some lovely audio as this began to happen in 2025. Join me as I share some wonderful audio of a wide range of species, as summer species began to flood back into Sweden.

In this, the final installment of the Sandemar Files, I take you on an auditory tour of Sandemar Reserve, exploring the wonderful sounds of this reserve on May. In late spring, this reserve bursts into life, as summer migrants return in large numbers to establish breeding territories. The soundscape at this site through the spring is quite remarkable and it is at its most diverse in May, when a large number of species are present. This year was no exception and I employed a number of field recording techniques to secure some wonderful audio at this very special reserve.
