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.

New Catfish Species in Australia

Carfish are fairly mundane creatures. If you are fishing and you hook one thinking it is a big pike you are annoyed when you drag it in, and "drag" it the defining word. They are usually a dead weight on the line.

On the other hand if you are a biologist all animals are of interest. A combined US, Australia team has discovered a new catfish species in North Queensland. It has a tail like an eel, not the usual fish-like tail. Apparently, people knew of its existence for many years and just assumed it was like any other catfish.

Tandanus tropicanus is cylindrical in body shape. It has a large head and tiny eyes. DNA tests showed that the fish is a distinct species. Overall, its body configuration is different from other catfish.

Unlike many catfish it is good to eat. Fishermen have been catching it for many years for food not knowing how unique it was. Despite the accumulation of human knowledge about the world there is a lot we still do not know about nature.
