FANTASTIC! I am really excited to be able to announce that my photo is one of the ten winners of the #RememberingLions photo competition. This shot will be published in a book called Remembering Lions that will be launched in October. There were more than 2,400 entries to the competition! The book is produced by @rememberingwildlife and their previous books are absolutely stunning and their goal for this bok is to make the most beautiful book about lions ever made. Best of all, all the money they make goes to conservation. Thank you for including me and I can't wait to see it in print. Serengeti, Tanzania.
Another photo of the close encounter I had with a Barred Owl off a boardwalk a few weeks ago. I was walking a popular nature trail boardwalk when I noticed this Barred Owl perched a few feet off the trail. I was not the only one to enjoy this special encounter. This owl gave many people who walked by a great experience. I am hoping it turned a few into birders!
