These are most beautiful animals that we love and respect. We hope and pray that the entire human race repents now and go Christian Vegan to honor the Holy Trinity in all that lives. The Christian Vegan way of life is mandatory for the entire human race, but it is not optional to any one of us. Plz read: The Lord Christ Jesus Was A Vegan and The Christian Vegan Revised Pslms by Saba. We all need to be Christ Jesus like in order to help these friendly animals to live on earth in a safe way possible. God be the King of the whole universe forever and ever. Amen.

The information regarding the 10 rarest birds is not correct. Although the birds shown are indeed very rare but the list is incorrect, certainly as of 2016.
