Two geese on the tree, is that possible?
Ria Doorn-Martens and her husband saw two birds high in the tree and wondered which were which and why they were in the tree. Both birds are Egyptian geese. In principle, the Egyptian geese belong to the family of swans, geese and ducks, but in this family the Egyptian geese belong to the subfamily of geese. Some people refer to these duck-like birds as duck geese.
Originally, these animals were found around the Nile, hence the name. In Europe they escaped from various bird parks and zoos. Since 1967 they have already settled in the Netherlands. Currently, the number of breeding pairs is estimated at about 12,000. In addition, these Egyptian geese love to nest in the trees, which are also originally the place where half of the geese and ducks nest.
What kind of strange flying creature is this?
In the photo sent to me by Rob Swinkels you see a black bug with yellow stripes and pretty red legs. This insect is called the wasp beetle, and this long-horned beetle also imitates it. The wasp beetle mimics a wasp. Many people are shocked when they hear the name of the longhorn beetle, but this is not necessary. Most of these insects are harmless to us. Especially this little hornet.
Adults mainly eat pollen. Sometimes the females eat another insect. You also don’t have to worry about caterpillars doing anything to your home. The creatures live in and feed mainly on rotting, deciduous wood. You see them most often in beech trees, but also occasionally in dead trees that have been affected by a fungus.
Is that a Japanese weed in planted flower beds?
Mathisen sent me a picture and asked if the large leaf and inflorescences came from the Japanese knotweed. I regret to report that this is the case. Large leaves with slightly red veins and white flowers in the spike really indicate this. The best part is that Elly removes everything instantly and burns or destroys the materials he removed. It’s best not to throw the Japanese knotweed in the green trash. Also have a look at the Wageningen University website for more tips.
Insect observed last week in Carinthia What is it?
Anja Hurkmans sent in a photo of an insect she encountered in Carinthia. I immediately saw that it was a long-horned beetle. Unfortunately, I didn’t get to know the specific types, so I searched the books.
The name is Kleine Helenboktor and it is actually found in the Netherlands, but it is very rare, seen only in southern Limburg. These long-horned beetles are common in warm places and like to perch on thick trunks and branches of deciduous trees. Preferably in open deciduous forests, but also in orchards, gardens and along roads. They love ripe fruit, but they are also flower visitors.
Very strange: this hole is turning pink, what is going on?
Auke van Veen was walking when she came across a wide hole whose water was colored pink. We call this phenomenon the evolution of red algae or purple sulfur bacteria. These bacteria develop due to a certain percentage of nitrogen and phosphate concentrations in water and high temperature. This makes the water turn pink, and it can turn burgundy. Swimming in such waters is not smart, because purple sulfur bacteria are poisonous. So watch your dog, cat or any other animals and don’t let them drink from this ditch.

Red Kite Flying – Fish Thief
Publication date: 4 Jun. 2022
More and more birds of prey than hawks are being spotted in our county and this may be true. For example, the red kite appears more and more often. I loved this beautiful movie of the common tern tern, also called the red kite.
The red kite is one of the few bird species that occurs almost exclusively in Europe. Due to severe persecution, it greatly diminished and locally disappeared. Preventive measures put an end to it; Today the species is again found in our neighboring countries, although not in abundance anywhere. Food consists mainly of bait, as well as hunting prey the size of a hare.
There is something on the tree trunk what is it?
Margo Doll discovered an orange substance on her tree with her grandson and wondered what it was. The tree appears to be a conifer and this pine loses a sap, possibly through holes in the tree. This resin is a natural protection for conifers, for example against insects and fungi.
The resin is not dangerous to humans, it is only sticky when touched. In the past, the resin was used as a medicine, especially against bile acids in the intestines. Furthermore, hard resin was used to lubricate the arc’s bristles.
Is butterfly thistle rare?
Marij van Drel saw a spiny butterfly and photographed it and wondered if this was a rarity. Thistles are migratory butterflies that come to Holland from southern Europe and Africa. The numbers vary each year, so the number of thistles can vary from year to year. In my opinion, in recent years, thistles are coming to our country more and more and their rarity is decreasing.
The researchers also found that entering desert sands leads to infestations of thistles. They can be observed here from April to October and they provide offspring every summer. Some of those offspring are moving south again and some are dying here in our country.
