A very strange animal, even Frans-Kaptens had never seen it

Forest ranger Frans Kaptijn shares his knowledge of nature on the radio every week. Listeners can ask questions at [email protected] This time at Stuifmail, he’s paying attention to mushroom-eating mushrooms, springtails on cap mushrooms and deadwood birds.

Omroep Brabant also broadcasts the TV show “Op pad” on Tuesdays, in which viewers are taken to the nature reserves of the Brabants Landschap. As a viewer, you can also walk the route from the program yourself. There is a special program Develop a walking application.

Is this a frog or something else?
Yvonne van S’s grandson saw an animal that looked like a frog, but was not. When I saw the picture I thought of a frog, but I was very skeptical. The animal looked very strange and I had never seen anything like it. So I enlisted an expert at Ravon, the reptile, amphibian, and fish knowledge organization. Ravon came up with the following response: “This looks like a very emaciated common frog (bufo bufo). Wasting can have various causes such as pathogens (parasites, bacteria, viruses), a malfunctioning immune system, contaminants (substances that inadvertently occur in food) or a combination Of these. It cannot be determined without additional research.

Mushrooms “eat” boletus
Jose Gerts sent me a picture of a small fish with a white hairy mushroom on it. I think they call such a mushroom a boletus rot. When the fungus – a cap with a stem – and a mushroom – a cap without a stem – have done their job, they are “cleaned”. All mushrooms and fungi—which are actually fruiting bodies—are eaten after all the spores have left the mycelium or mycelium. In this case, boletus. This eating can be done by people (you can eat boletus), animals or other fungi. You can say: nothing survives in nature, because everything revolves in the ecosystem.

Dead bird on the balcony
Mickey Crum saw a dead bird on her porch. I thought of a sniper or a bird. In her image I see a lumberjack. Wood birds have long beaks and rusty brown feathers with black spots. On the black back of the head you can see two light stripes. Woodcocks also have a short tail. It can grow up to 38 cm and is therefore the largest in the world of cannibals in the Netherlands. Woodcocks mainly have earthworms, grasshoppers, and caterpillars in their menu. By the way, you don’t see these birds often, as they lead a rather solitary life and are very shy. So they – just like rabbits, for example – sit motionless until the last moment. Then all of a sudden they shoot right in front of your feet and before you know it, they’re gone. In some areas, they call the woodcock the “long-faced lady”, because of its elegant appearance and distinctive beak.

Are springtails insects?
Henk Siba sent me a beautiful and well-made photo of springtail on a mushroom. He has three questions: Is this an insect, where do these animals stay in the summer when the weather is dry and how do they reproduce. Well, springtails are not insects. The group to which the springtails belong forms, together with insects, the rhizome of hexapods. This root again falls under the class of arthropods. The difference between the two is in the mouth parts. The clubtail and a few others have mouthparts located in a sac inside the head, and insects have mouthparts on the front of the head. Through research, it was discovered that springtails actually belong to the class of crustaceans rather than hexapods. Their reproduction is also very special. In fact, they don’t have sex. The male leaves a kind of sperm sac that the female must pick up. Finally, the third question. Springtails mainly live in soil in climates with high humidity. In dry summers, you may occasionally come across them on their way to moist soil.

Not from a top hat, but from a coat
A very beautiful spider jumped out of Corey Duendam’s jacket. I wondered what this spider was. I think this is a bark spider because of its inconspicuous brown coloration and rather gray back part of the abdomen. On that belly, you also see a kind of dark V-mark graphic. Bark sack spiders are nocturnal hunting spiders that hide during the day. This shelter during the day can be a spun sack, but they can also hide under stone or bark, among vegetation, or in a jacket. Bark sack spiders belong to the bush sack spider family. The males of this type of spider are almost as large as the females. Females grow up to eleven millimeters and males up to ten millimeters. Try to see this in spiders escaping from the bark of the bag.

Garden full of amphibians and reptiles – early birds
All kinds of beautiful reptiles and amphibians – except for the viper – live in the Netherlands. She’s pretty to look at, but could also use some help. How do you make your garden a paradise for frogs, salamanders, lizards, and maybe even grass snakes? Edo van Oechelen, author of Practical Nature Management: Amphibians and Reptiles, presents it in the video above.

A large ring around the Sun, seen in Netgey Janus
Frank Bentinck saw a huge ring around the sun at Neeltje Jans for much of the day. he wondered what this is. We call this ring as in the picture Frank Halo. You actually see a circular, fuzzy circle of light around the sun. Halos occur in sunlight and moonlight. It’s a phenomenon that manifests itself when light from – in this case – the sun is refracted by ice crystals. If you see halos, high clouds are present at that time. We call those clouds cirrus clouds. In fact, the name halo is a collective name for a family of light phenomena that manifest themselves in the sky. Halos can be seen near the sun or moon and then in all sorts of shapes. It can be stripes, but also light spots, and therefore circles as well. white and colored.

What are the mushrooms in Halsteren?
Martin van te Hove sent me some pictures of his brown Bullets. He thought of a brown ring. I myself think that it is a porcini mushroom, because of the thick leg. Brown ring screws have a thinner, often light-colored spline and a ring on that point. Now I can’t see all the stems properly under the hat, but the stems I see are not thin but thick. That’s why I stick to porcini mushrooms. You can encounter porcini mushrooms from July through November. Boletes often grow with different types of trees and this is also the case with porcini mushrooms. This fungus does this by fusing mycelial hyphae with tree roots. We call this mycorrhiza. Porcini mushrooms are characterized by their fusion process with native oak trees such as slash oak, birch oak, and American oak.

Nice pictures
The front door camera of Marion de Young’s house showed one morning that someone was at the door. She saw through the camera that it was a nutcracker. She thought this was so funny that she took a picture of it.

Nature advice
since then On November 16, you can take part in the outdoor escape “into the woods” of the IVN Oisterwijk Visitor Center. In Outdoor Escapes, you are not locked in a room, but you are going into the woods. This outing is inspired by an escape room, but here you are in the beautiful Oisterwijk forest and fen area. In collaboration with Oisterwijk Adventures, three different outdoor escapes have been developed that can be booked from now on.

Take on the challenge with a group of friends or family. You get a bag and go to the forest with it. Along the way you will encounter many tasks and puzzles. Will you be able to go back in time with the code phrase hidden somewhere in the woods?

You can choose from three different outdoor escapes:
1) Veins: 45 minutes, difficulty ***

2) Fermentation vat: 45 minutes, difficulty ***

3) Chorven: 60 minutes, **** difficulty

For more information and reservations, go to the Oisterwijk Visitor Center website.
