One species, the black metaltail (pictured), reached the lowest temperature of 3.26°C.The frigid internal temperature at night allows the tiny birds to prepare for the big day ahead.Researchers from the University of New Mexico looked at 26 hummingbirds from six different species living in the Peruvian Andes.These birds survive at altitudes of up to 13,000ft (4,000m) and researchers trapped them and inserted a small temperature probe into their rear while they rested.Researchers recorded the core body temperature throughout the evening and compared that to the outdoor temperature, which could drop as low as 2°C (35F).Dexterous hummingbirds can flap their wings up to 5,000 times a minute to create their signature drumming noise.This skill means that up to 30 per cent of their body weight is made of flight muscle while for most birds it is around just 15 per cent.This abundance of strength makes them excellent flyers and now researcher have found that even the largest of the hummingbirds are as skilled at flight as the tiniest ones.The larger birds have evolved differences in muscle power and wing size - along with a touch of skill - to improve their in-flight agility.Depending on species, the hummingbirds entered torpor for between two and 13 hours, the researchers write in their study, published in the journal.The species in torpor for the shortest period of time was the giant hummingbird, while the longest was the black metaltail.The black metaltail also reached the lowest temperature of all individuals in the study, with academics recording it as low as 3.26°C (37.8F). �Adҁ��/����I�e4�GD�Th9�#9�B4�Ҥ�蜲\r2� �#�\�5��FUѠ�`7�P�vQm0mD��"Ԓ�F�v�Yd"��E����Q��m%��#+uHߐ��g9A��Iy�V��Q�7A(�Zq�� ��lf5�m�j��h�8���P�T�s;��p7��p�${���:]�A��c:\��̍j�;��>L$�`7LH`�4�b�9�Cp�4�Cc��8� j����>�3h����N��oj��2HbD��{���3��:��+I�¿� ����c�� 1���a��j ��cQ�5+ 'You'd think they're frozen,' lead author Professor Blair Wolf told.The birds exit torpor around sunrise and their body temperature soars at a rate of 1°C a minute until they're back to their normal temperature of about 40°C (104F).This rapid warming uses lots of energy up, but the amount the birds save outweighs this cost, the researchers say.By weighing the birds as they slept, the academics also found that the birds which were in torpor for longer lost less weight, therefore indicating they saved more energy.Torpor is a process used by very few species as it greatly increases the risk of predation.For the hummingbirds found in the Andes, this is of little concern as there are very few predators at that altitude.Other animals that employ the daily hibernation strategy include night hawks, lemurs and hamsters.The species in torpor for the shortest period of time was the giant hummingbird (pictured), while the longest was the black metaltail.The comments below have not been moderated.The views expressed in the contents above are those of our users and do not necessarily reflect the views of MailOnline.We are no longer accepting comments on this article.Part of the Daily Mail, The Mail on Sunday & Metro Media Group,Discover deals on home essentials and electricals,Apply AO.com voucher codes to save on home appliances,Check out the latest B&Q clearance for great offers,Keep yourselves entertained with these electrical offers,Check out the latest Wayfair sale to save on furniture.World's 'smallest dinosaur' is actually a LIZARD: Scientists...The world's smallest dinosaur: Two-inch long proto-bird is...Hummingbirds can identify at least eight colours that are...Three-inch Amazonian Hummingbird is the world's best-adapted...Ancient footprints found in Saudi Arabia reveal how humans may have followed lakes and rivers to migrate...Terrifying seven-foot tall robots controlled by a human using a virtual reality system are stocking shelves...Orphaned chimpanzees are found to face lifelong setbacks, as mothers teach foraging and social skills, study...Average worker gets 'career burnout' at age 32 - and 59% now say that they do MORE hours working from home...New York City is set to develop a four-million-square-foot climate change research center on Governors...Shazam it!
