Spring is here, and the New Yorker's optical illusion cover is one of the most delightful celebrations we've seen this year. At first glance, the cover for the magazine's 15 April edition features a beautiful illustration of various species of birds, the composers of the season's soundtrack, but there's more going on than immediately meets the eye.
First up it turns out that not all of the birds really exist. Readers are challenged to identify the real species and to detect which birds are made-up intruders. And there's another twist. The artist, Peter de Sève, has also included an optical illusion as a little hidden Easter egg in the design. Can you spot the cat?
