The Greater Sage-Grouse is certainly a formidable-looking bird. Being the largest grouse in North America and having tail feathers, which look like giant spikes, make for a ferocious sight. These birds are well known for their complicated courtship rituals, in which the males perform a special “strutting display” to attract the females. Another distinct feature of the Greater Sage-Grouse is two large yellow throat sacs (gular sacs), which are inflated by the males during the courtship display. Unlike pelicans, whose gular sacs are used to store fish while hunting, the throat sacks of the Greater Sage-Grouse are merely for display.

These Halloween horrors were all carved out of humble pumpkins by Ray Villafane and his team of professional sculptors who meticulously carved the terrifying characters using spoons and scalpels. Each one takes on average two hours to complete – with the horrifying results netting Villafane, plus colleagues Andy Bergholtz and Chris Vierra, numerous TV appearances each Halloween. This year the team has gone global travelling to Germany, Switzerland and Hong Kong to create their masterpieces.

Talented French artist, Pierre Beteille, is skillful in manipulation of portraits (specially his own self portraits) using Photoshop. This is how he describes himself: “I am not a photographer or an artist, I just make images… I shoot very average or even bad photos that I try to improve thanks to Photoshop”…
