the tail is rounded, with 10 rectrices, the central pair being bright bronze green, the same color shown in the sub-central pair,” Dr. Lopes and co-authors said upper and lower wing coverts are bright bronze green with the pileum darker with coppery reflections; post-ocular white spot; remiges are bluish black with a metallic shine; underparts are uniform light grey except abdomen whitish; undertail coverts are light grey.” but males in definitive plumage have the shafts of the three outer primaries and strongly bent distally; and bill slightly shorter and straighter than that of female.” The dry-forest sabrewing (Campylopterus calcirupicola) The dry-forest sabrewing inhabits dry forests on limestone rocky outcrops or on limestone-derived soils The altitudinal range of the bird is between 1,510 and 2,890 feet (460-880 m) but it was recorded visiting flowers of native and exotic species: Justicia sp. and Malvaviscus arboreus,” the researchers said Given the several threats faced by the habitat to which the dry-forest sabrewing is endemic, the team proposes to consider it as Vulnerable under the IUCN criteria “Campylopterus calcirupicola is uncommon to locally fairly common with a patchy distribution across eastern Brazil,” the authors explained “Indirect evidence suggests that this species has undergone significant population reduction in the near past and that this decline will continue in the near future due to decline in area of occupancy and habitat quality 11.5% of the dry forests of northern Minas Gerais were lost between 1986 and 2006 and the dry forests of the Paranã River basin suffered a 66.3% decrease in extent between 1977 and 2008.” given the several threats faced by the habitat to which Campylopterus calcirupicola is endemic we propose considering this species as Vulnerable under the A4 criterion.” “We suggest searching for the species in areas of potentially suitable habitat in Goiás and an increase in the size and number of protected areas with suitable habitat is also strongly encouraged.” The new species is described in a paper published in the May 15, 2017 issue of the journal Zootaxa A cryptic new species of hummingbird of the Campylopterus largipennis complex (Aves: Trochilidae) Zootaxa 4268 (1): 001-033;

Ribeiro approached his friend back in December who graciously agreed to do the hand-splitting surgery for free The process started by doing surgeries on his hand to remove excess oil and fat Ribeiro said he "began to see the possibility of making an opening in it through the middle where you can have opening and closing movements and a firmer folding of the hand!" and now Ribeiro's split hand joins his expansive list of body mods that include fanged metal teeth and several subdermal implants in addition to numerous piercings Ribeiro said he's "happy with what I did I don’t feel any change regarding hand mobility Cover photo: Collage: Screenshot/Instagram/marcelobboy More on Tattoos: we're happy to send you some reminders Click 'OK' then 'Allow' to enable notifications Home> News> World News An artist has opened up about his decision to undergo three operations to modify one of his hands Marcelo De Souza Ribeiro - who goes by 'B-boy' - from Bocaiúva Brazil got his first tattoo at the age of 15 and has continued to alter his body ever since the father-of-two embarked on a more drastic change in the form of undergoing three one-hour-long surgical procedures to modify his left hand Already having had his ears modified to look like elf ears it's fair to say Ribeiro wasn't as fazed by the prospect of getting his hand modified as most of us would be He told Business Insider the three procedures conducted on his left hand were 'smooth and not painful,' despite being performed by a friend for free - although Ribeiro - who has over one million followers on Instagram - explained: "I can now open the hand laterally and fold it in two parts." Ribeiro explains he thinks of his body much like an 'art exhibition' the artist reportedly having spent around $35,000 dollars on his alterations While Ribeiro is known to many as 'the most modified man in the world' - which seems believable given the lengthy list of procedures he's undergone - that's not actually the case, at least according to Guinness World Records 62-year-old Rolf Buchholz from Germany currently holds the world record title for not only the 'most body modifications (male)' but also the 'most piercings Verified in 2012, 'he totalled 516 body modifications, among which there are several implants and 481 piercings (278 alone on his genitals), but the number has increased over the years,' the site explains Buchholz reflected: "I didn’t do it for the record with Buchholz's world record verified over 10 years ago perhaps it has since been overtaken and potentially by Ribeiro UNILAD has contacted Guinness World Records for comment Topics: World News, Beauty, Health, Social Media, Guinness World Records A tattooed dad with 98% of his body covered in more than 1,500 tattoos and several body modifications has inspired his kids to follow in his footsteps Marcelo de Souza Ribeiro (38) has more than 1,500 tattoos across his body he realized he wanted to take things further with body mods Before getting the metal fangs, Ribeiro told the Mirror that he had been wanting to get them done for 10 years "I love the shine and the look they have – they don’t impair my eating in any way." The tattoo-obsessed man also admitted that he wants to get more tattoos done in the few areas he doesn't have any yet like a small spot on his leg and his "more intimate areas." But Ribeiro isn't the only one who wants more ink his kids have expressed interest in following in his uniquely tattooed footsteps His 19-year-old daughter Hilary has apparently already started her tattoo journey getting her first piece of ink at the age of 17 and a handful more over the last two years Ribeiro even told the outlet that his nine-year-old son Aleff "always says he wants to get tattoos when he grows up." Speaking of his family's opinions on his body art which Ribeiro has spent roughly $33,000 on Ribeiro said they were "never against my way of living and liking tattoos – even my mother has several."
