Based on the bestselling book by Aaron Reynolds, this collection of pictures within this Effin’ Birds Calendar for 2023 takes a look at what all of the birds, hens, hawks and fowl around you are really thinking. Featuring detailed illustrations of badly behaved bird types along with entertaining captions, rude remarks, plenty of swearing and an impactful amount of humour, this calendar makes a great addition to the home of bird watchers across the nation.
