Black Woodpecker (Dryocopus martius)

Posted on November 30, 2018March 2, 2020 by Malu

Hi guys, what’s plotting?

I’m super excited, because I saw a pair of black woodpeckers today! In my rather outdoorsy life, this is only the second time ever that I’ve seen them in the flesh.

These birds are beautiful! All black, with cream coloured beak and eyes and a striking red mark on the top of their head. Males are red from the beak to the end of the head, females, only on the back half of the head. This “sexual dimorphism” is already visible in chicks, as soon as they get their feathers. For a woodpecker they are quite large with a rather thin neck.

My favourite thing about them is one of their calls, their “flight call”. It sounds like tropical frogs. In my opinion. Here’s an MP3:

And here are other sounds they make:

Where and How to Find Them

I was too slow and far away to take a picture for you, so I attempted to draw one for you.

Black woodpeckers occur mostly in boreal and temperate, not too dense forests, where they make nesting holes in tree trunks. You may be able to recognise their nesting holes by the bark around the lower edge of the hole removed, and the wood beneath carved at an angle, so that rainwater will run down the outside of the tree, keeping the nest dry. Look for the holes at about 10 to 20 metres above the ground. The hole is about 13cm high and 8cm wide.

The best time to see woodpeckers in general is probably in fall: All the leaves have fallen and the woodpeckers are busy getting the insects out of the bark, crating that classic knocking sound, that carries quite a few kilometres. Listen, look up, appreciate a view unobstructed by leaves.

 

Why we Need Black Woodpeckers

This species builds long lasting nests by hollowing out holes in living tree trunks. They prefer mature beech trees, and they have an unknown method of figuring out that a specific tree is already rotting on the inside. They then peck through to the rot and simply remove the softened wood there to make a hollow for the nest. And these guys don’t make a house for life. They make many nests throughout their life-time. Holes in trees, you may think, that’s a bit shit. But because this bird is so productive, it is a “key species” (self explaining ecologist term) in the ecosystem, providing hiding places, and therefor better survival chances, for about 50 other species: Ranging from insects, like wasps and bees over birds of all shapes and sizes, particularly stock doves (Columba oenas) to mammals, including edible dormouse (Glis glis) some endangered bat species and even the woodpeckers greatest predator: the pine marten (Martes martes).

Black woodpeckers help keep the forest healthy, because they eat wood-boring grubs and insects that are horrible pests to the trees. And there is on-going research about how these woodpeckers benefit fungi and their role in a healthy forest system.

If you are in temperate or boreal Europe or Asia, now is a great time for a walk in the forest and a listen for the sound of rain forest frogs. Maybe you’ll see a crow hanging from the side of a tree, be confused, then see a flash of red and be as excited as me.

How  to Protect Black Woodpeckers

Black woodpeckers are not considered endangered by IUCN or Birdlife, because their range is so big. There is some trouble in paradise because they like the same kind of trees as timber industry, so they don’t do so well in commercial forests.
What you can do, is tell a friend about them so that they appreciate this species too. Appreciation is always helpful in conservation.

    About me

    My name is Malu. I am a conservation-ecologist currently living in Germany. I’ve always been wild about the outdoors and can spend hours looking at an insect labouring away at its daily challenges, or a bird building its nest, or … there’s just so much amazing stuff happening out there! I’m really glad you’ve made it onto this page so I can share my joy with you.

    Monthly Challenges

    We only have about 6 to 8 years left to turn this environmental mess of a ship around. So much has to happen politically, but the people also need to change habits and start to appreciate our environment more. So every 1st of the month I post a nature care challenge with environmentally friendly lifestyle choices of habits for you to try for 30 days and, if you like, let it stick with you for longer, maybe even for life.

    Lots of little droplets make up the largest ocean.

    Are you absolutely unable to do the current challenge? Or maybe you are underwhelmed with the challenge and want an extra one? Check out the previous challenges to see if there is something you would like to try.

    The challenges  make up the major part in the flow of posts here, so they are easy to find. But if you want to get a good overview of the challenges set so far, simply follow the link below.

    Do you want to set next month’s sustainability challenge?

    Contact me and pitch your challenge to me. It might be up next month. You can either write the whole challenge, and why we should do it, or just give me an idea for something to look into.
