The competition, founded by photographers and conservationists Paul Joynson-Hicks and Tom Sullam, announced the top 44 images on Friday.
This year, they include a fox in heavy negotiations with a mouse, a bear waving hello and a Kingfisher landing on a “No Fishing” sign with his catch in his beak.
The awards both showcase funny images of earth’s wildlife and raises awareness for conservation.
The Category and Overall Winners will be announced on October 22.
Joining Mr Joynson-Hicks and Mr Sullam on the judging panel is wildlife TV presenter and writer Kate Humble, actor and comedian Hugh Dennis, wildlife photographer Will Burrard-Lucas, co-founder of Amazing Internet Andrew Skirrow and Photographer Simon Pollock.
Wildlife expert and co-founder of BFF Will Travers OBE, Managing Director of Affinity, Ashley Hewson, the Telegraph’s online travel editor Oliver Smit, Bella Lack, an inspiring and next generation conservationist and finally Celia Dunlop, a brilliant picture editor, are also judging the competition.
But the public can also vote for a winner of the People’s Choice Award.
The top image will win a one-week safari with Alex Walker’s Serian in the Masai Mara, Kenya as well as a unique handmade trophy from the Art Garage in Dar es Salaam, Tanzania.
The competition is also supported by The Born Free Foundation, Affinity photo, Amazing Internet, Think Tank, Alex Walker’s Serian, Spectrum Photo and Nikon.
To raise promote how to be a “conservationist at home”, the CWPA said: “With the recent lockdown, we have all got used to doing things slightly differently, including shopping closer to home, so why not carry on?
“It helps in all sorts of ways from supporting small, local businesses to shrinking your carbon footprint and is way more fun! And if you can avoid buying un-recyclable products and one-use plastics/packaging, even better.”
“One of the easiest things to do… put a plant box on your windowsill, grow some flowers, and give the bees somewhere to go,” it added.
