Wild Bird Acoustics

Sweden is world famous for its stunning vista of remote freshwater lakes, lined with coniferous forest. Happily, this scene is still very much a reality in the modern day. At Tyresta National Park, a stones throw from Stockholm City, lie a number of freshwater lakes and in the spring of 2024, I was drawn to them once again. Having undertaken a major field recording project at the park, I wanted to uncover the secrets of the lakes within the park. I was very much focused on field recording of one of Sweden's most iconic sounds, the breeding display of Black-throated Diver. This endeavour proved not to be as simple as I had anticipated, but there were some wonderful moments along the way, as I tried to get to grips with my target species. Did I succeed in the end? Join me in this episode of Wild Bird Acoustics in order to find out...

March in Sweden is a period when resident species begin to become active after a long winter here in Sweden and woodland habitats begin to ring with the sounds of singing birds once again. In 2025 I visited Tyresta National Park throughout the early Spring period in order to record these resident species, before the return of summer migrants. I was interested in recording the soundscape within woodland before it became saturated with the song of a wider range of species. In effect, the sound of woodland in early spring is rather pure and it is an excellent time to obtain high quality recording of several special species, such as Black Woodpecker and Red Crossbill. I found a wonderful soundscape to record within the park, as I traversed this massive tract of woodland in search of birds. The results of this intensive sound recording project were quite wonderful and surpassed my own expectations. In this episode, I share recordings from that early spring period, just before most migrants return to Sweden.

Northern Sweden is a field recorders dream and a place I return to at every given opportunity. Each summer, I return in order to relax and spend time in nature, allowing the sounds of the natural world to seep into my very being. It is an incredibly relaxing place and one I wish to share with other's. Places like this are increasingly rare in the modern world... 
 In this episode I present the audio I collected over the course of July 2025 from the tiny island of Hällögern. Most of the month was spent recording various breeding species, often watching them for long periods in order to figure out where best to deploy my recording rigs. Having an abundance of time on my hands was a rare gift and the result was some rather special audio. This will be the first of a number of episodes where I share audio from that particular period on the island and I hope that listeners will enjoy every strophe of it...

In this episode I present a feature length sound magazine, put together with audio from a field recording project  carried out at Sandemar Reserve in Sweden. In May 2025, I decided to concentrate heavily on this incredible site, using both active and passive methods of recording. A great deal of time was spent at the site at a time when the reserve is at it's busiest. Sandemar Reserve is an area that I have become extremely familiar with over the years and I have now birded regularly at the site for over twenty years. Over that entire period, the site has continually thrown up  surprises. From my experiences here, I knew that a focused field recording project though the month of May would result in a large amount of remarkable audio.  Over the course of a month I visited the reserve many times, greatly enjoying the sounds of this incredible area, which is blessed with a multitude of different habitats. As migrants began to stream through the area and breeding species began to take up territories, the soundscape became more and more varied. Some rather special local species were among them, along with a few surprises. The more I drilled down, the more I uncovered...

In this episode I present two sound magazines for listeners. The first of these concerns a single day at Ågesta Reserve, just south of Stockholm City. I visited the reserve on 10th May 2025 and spent a wonderful morning actively recording a large amount of species at the site, moving from one bird to the next, simply enjoying the rich and varied birdlife at the site. On the day, the place was alive with birds, all of which were extremely vocal and I secured a large amount of wonderful audio in this single visit. On days such as this, it is simply incredible to be in the field, here in Sweden. 
The second sound magazine should appeal to all those who regularly tune in to Wild Bird Acoustics and are interested in nocturnal migration. Here I discuss some of  the better audio recordings I managed over the course of spring 2025 at my main listening station at Landsort, Sweden. 2025 was an extremely productive season of spring migration and I have plenty of interesting audio to share. Join me as I lift the veil on nocturnal bird migration over the Stockholm Archipelago.
