Liquid crystals from a mobile phone

Liquid crystals from a broken screen of an old mobile phone. The photos are made under the microscope and in polarized light.

Aloin under the microscope

Aloin or Barbaloin is an ingredient in many aloe species. The substance is precipitated on a microscope slide and photographed in polarized light.

Rüppell's Vulture

They are not the animals people looking for. I saw this Rueppel's vultures during a trip in the Masai Mara in Kenya.

Sigiriya in Sri Lanka

I made these photos some years ago during a trip in Sri Lanka. Sigiriya is an ancient palace placed on a large monolithic rock. The palace was built in the 5th century B.C. and is famous for some frescoes painted in the rock walls. The paintings are called cloud girls and the remains of a large picture gallery. From 500 frescoes 22 are preserved.

African Montane White-eye

The African Montane White-eye is a small bird endemic to Eastern Africa. I saw this bird in an acacia tree in the West of Addis Ababa in Ehtiopia. They are beautiful, but inconspicuous birds and sometimes diffucult to spot.

Abyssinian Horses

The Abyssinian horse is a horse breed from Ethiopia. The light horses are accustomed to life in altitude mountain areas up to 4000m above the sea level. They look fragile and small, but they have to work hard and can be strong working horses. Especially on the countryside and in small cities, they are used as for transport and riding. I saw these horses close to a road and could not convince it to raise the head for a photo (the rains were long enough, it looks just strange on the photos).

This was the original reason to stop: A pair of Red-billed Oxpeckers resting on the horse back.

Rainbow Cloud

It looks like a rainbow in the cloud, but is just a case of cloud iridescence. I saw it last week near Nuremberg in Bavaria.

Ice and magnetism – a view through the microscope

Water is a diamagnetic material, which means, it is reacting in magnetic fields. This is a simple experiment to see how a magnetic field influences ice crystals during freezing; water was dropped on a microscope slide that was placed on neodymium magnets and frozen by -25°C. The photos are made with a cooled polarization microscope with the 10x objective and a 2,5x photo adapter. Under the microscope, the ice crystals show completely different habit than “normal” ice crystals. They are smaller, partly cubic or with an irregular shape.

Waders in the evening

My birds for this week are photographed on a late evening walk along mangrove forests and mudflats in Gambia. There were many Whimbrels and a mixed group of Stints, Redshanks and Spur-winged Plovers. They waited for the tide and were good to watch.

The tidal flats in front of the mangroves:
