PORTLAND - The Oregon Zoo is preparing for the birth of an Asian Elephant. Rose-Tu is close to delivering her second baby calf.
You can follow all the updates at the zoo's baby elephant blog.
Elephant keepers are checking Rose-Tu’s blood for changes in progesterone level, which would indicate labor is ready to begin.
The Oregon Zoo has fifty years of experience in birthing and raising Asian Elephants, and a very high success rate to go along with it.
Zookeepers and watchers are excited for a healthy finish after 20-plus months.
