Banded Stilts Water Bird Always Finds the Water

As soon as inland rain arrives at Australian lakes, the banded stilt water bird makes its presence felt as well. It somehow knows that the rains have started from several hundred miles away.  This useful ability determines their way of life.

They don't hang about long. Rainfall will be limited so they move on to the next fresh rains spot. Birds were tagged with satellite transmitters. One bird flew directly to a saline wetland 1,000 miles away in two days. Another bird got there four days later, but the destination for both was the same.

Banded stilts do not have to migrate for improved feeding conditions. Their inbuilt system allows them to always find water. Why don't other birds do this? Obviously, evolution is "hit-and-miss". Animals develop abilities purely by chance. This is why evolution is successful. Animals move into niches that line up with their attributes.

A New Mineral Called Putnisite is Found in Australia

Minerals are classified into species like animals. You would think that all minerals had been identified by scientists. This is not the case. A completely new mineral has been found in Australia at Polar Bear peninsula, Southern Lake Cowan. It is named after the two scientists who discovered it, Christine and Andrew Putnis based at the University of Münster in Germany.

Putnisite is now among the 4,000 known minerals. It was found on the surface of Lake Cowan in Western Australia. The mineral is composed of tiny 0.5 mm diameter crystals in volcanic rock. Its crystals are square and in a range of colors: white, pink, purple and dark green. The mineral is composed of oxygen, hydrogen, carbon, sulphur, calcium, strontium and chromium. It glistens as light can penetrate the substance.

Unlike other minerals which belong to families similar in structure, putnisite is unique. Nature joins things together to form minerals. Scientist did not believe a blend of these bases could be joined together as a unit. Researchers are clearly not as clever as nature itself.
