Night recording in Dyrehaven, May 28th 2017

This is an all-night audio field recording from Jægersborg Dyrehave, north of Copenhagen, 28-29th May 2017.

So, this time I managed to do a night recording in a forest a bit further away than my local Brøndbyskov. Jærgersborg Dyrehave is a much older and larger woodland (royal deer garden), know for a large population of old oak trees, Eremitageslottet and just plenty of deer. For a long time, I have been curious to know more about the night sounds of this old historic forest.

It is just a great time of the year, everything so fresh and green with tense smells of moist soil and vegetation. These few weeks of the year with such a high activity among birds, mammals, plants and insects, I think it could also be called it a stressful time of the year.

It was a calm night with warm temperatures 18-12C. Recent days had been full summer days with temperatures >23C, dry and lots of sun. For the recording, I found a place some distance away from the paths, with tree trunk suitable for my tree ears microphone setup.

Below you can hear 2 clips from the night take (listen in headphones):

0:30-1:00 am – Deep night sounds and loud animal scream

Just past midnight, the deep noise from the amusement park (Bakken) is still clearly heard, but declining. Generally quiet night ambience, still somehow affected by (partying) humans.

At this time, there footsteps of deer walking around nearby.

About 6 and 8! minutes into the clip, out of the silence there is a sudden very loud screaming  (warning loud !)  of some sort of animal, very close. Does anyone know what species this is and why it is screaming? I am far from having any clue, just think it sounds more like a mammal than a bird.

2:50 – 6:00 am – Morning chorus

The clip starts 2:50 am. Now the noise from Bakken is gone and the traffic noise is also at a minimum, all in all making this period a very undisturbed silent night ambience.  Occasionally, you can hear a woodcock and an owl-like call.

However the first light is emerging and15 minutes into the clip the first robin decide to start the day with quiet singing. After 10 minutes the song thrush joins in with a beautiful soft song, and now the whole forest is clearly waking up.

At 1:00 there is some unusual bird song. I think it appears to be a Black bird, that suddenly changes its song into a funny exotic melody. Maybe a black birds that was raised amongst parrots? Never heard that song before. Anyone heard that before?

The bird song is peaking at this time. The main voices of the morning chorus are wood warbler, black cap, black bird, song thrush, wren and robin.

It is always a special experience to listen through an unattended night recording, never knowing exactly what to expect. This recording was no exception. The process takes much longer than the actual recording, typical a few days. But after, it is like coming back from an expedition, with a whole new understanding of that particular place.

  1. It sounds like the scream of a vixen to me – have a listen to one here :-


  2. Reference the Blackbird – I haven’t heard one like that before – quite amusing, but they have an amazing repertoire of calls, and will mimic ringing telephones, whistling milkmen (that’s when they used to deliver & whistle :)), etc.
    Nearby blackbirds can be a problem when trying to record the dawn chorus, as their sounds are so powerful that the gain has to be turned down to avoid clipping, thereby missing all those other more delicate, distant sounds.


    • I have heard black birds imitate shorter sequences in their song, but this bird have clearly taken it to the extreme. All probably completely normal from the view of natural variation.
      I think this black bird is at a good distance to blend well into the dawn chorus. The black cap, on the other hand is a little dominating through out this recording, maybe.
      If it had been sitting just a little closer, it would have started to be a bit of a solo chorus…
