Birds on the Hainberg area

Some birds from the Hainberg, a nature protected area near Nuremberg. The birds are shy, with a high escape distance (there are many joggers, mountains bikers and dogs) but I had the luck to see a Cuckoo and a Winchat.

Chimpanzees in the Kalinzu Forest

The Kalinzu Forest is a protected area in western Uganda near the Queen Elisabeth National Park and famous for his chimpanzees. Beside the Bwindi National Park with the Mountain Gorillas, the Forest is one the highlights for safaris in Uganda; it is fascinating to see the chimpanzees in the wild.
I made the photos on a guided tour some years ago. The chimpanzees are habituated but they are not so peaceful and close to see, like the mountain gorillas. We had a two hour trek through dense forests and had the great luck to find a group of 8 apes including a mother with child. They were hidden in the trees and made, in the first moments, a very aggressive impression with a lot of yelling, jumping around and throwing branches after us. After a few minutes they have calmed down and we were able to watch them about 20 minutes; before they disappeared in the forest.

These two were probably the leaders of the group.

To see the chimps is not guaranteed, in the guest book of the park administration were many entries of groups who saw no animals. The walk through the forest is great, the dense vegetation with tree ferns and an almost closed canopy make a unique atmosphere. We saw only few other animals; some fast black and white Colobus monkeys and Olive Baboons living on the edge of the forest (our guide told us, that the move into the forest by farming pressure).

Cloudy sky

This was the sky last week as a storm raised. We have always rapidly changing weather in April and the change between blue skies and rain can go fast. In this case, the hail came within a few minutes.

Common Firecrests

I was lucky to see some Common Firecrests last weekend. They are one of our smallest birds with just 9 cm in length. In my area they are relatively rare, life hidden in dense spruce forests and can sometimes observed at forest edges. We had a fast meeting and they disappeared in the bushes. It was almost night and the light conditions were medium.

Eating Muskrats

I have seen this couple of muskrats last week in a small lake. Their main interest was eat, swim and eat more; with a curious style of swimming. One lay without moving in the water and stuck her tail in the height.

Gravitropism by Fomitopsis pinicola

This is an old Red Banded Polypore (Fomitopsis pinicola) that’s grown on a spruce. After the tree was overturned, he had to change the grow direction. The process is called gravitropism and means a turning of growth in response to gravity.

Cardinal Woodpeckers

It was a brief encounter in Gambia. First I saw only a red spot in an old tree and recognized the Cardinal Woodpecker.

Food under a microscope

This is a collection of posts with photos of food or food compounds under a microscope. Many of them are chemicals used as additive for conservation or coloring. The photos are made on a polarization microscope and show crystallized, dry samples. The structures become colored and visible by the polarized light. Few are extracted by micro-sublimation (like caffeine). Sometimes it's incredible what we eat every day, some samples form very aesthetic and surprising structures. The collection has no scientific purpose and is made of samples that can be found in products of daily life.

The collection is in alphabetical order and will be expanded in the near future:

Hypogymnia physodes and lichen acid

The lichen Hypogymnia physodes is very common in Germany. It grows on trees bark with a low pH or on trees grown on silicate soils. This specimen was grown on an old stup.

The lichen has no fluorescence or color changes under ultraviolet light, like other lichen.

Lichens are small chemical supermarkets. The constituents are called lichen acids and can involve more than 600 different chemicals. This is the lichen acid of the Hypogymnia physodes lichen extracted by micro-sublimation. It is made of small white crystals in polarized light.

Fishing Great Crested Grebe

This fish was almost too big but he managed it; a Great Creasted Grebe with a freshly caught fish.
