Southern Yellow Bat: 19 Facts You Won't Believe!

Southern yellow bat facts are interesting.

The southern yellow bat is a type of vesper bat and belongs to the order of Chiroptera and the family Vespertilionidae. Known for their unique yellow fur, southern yellow bats and northern yellow bats share many physical features.

However, the southern yellow bat is quite unique due to its year-round migration patterns. They fly in huge flocks over the sea towards the equator and southern portions of their range from the northern parts. Scientists have noted that male southern yellow bats become absent in the northern parts of their range during summer while the females stay in place. Their route can interfered with due to year-round wind patterns. Their migration patterns in the Southern Hemisphere indicate that these bats try to avoid the cold temperature.

Many of these bats are now at threat due to the rise of a disease called the 'white-nose syndrome' caused by the fungus Geomyces destructans. This fungus has led to mass deaths of these bats especially in the temperate climate.
