00:00these frogs were bright colors which oftentimes indicates they're an extremely poisonous variety
00:08but now they're being outfitted with pants for science this is behavioral biologist Dr. Andreas
00:14Pesukinas he and his team have been locating and fitting poisonous tree frogs in South America with
00:19little frog pants here's why to study any behavior in the field first you need the ability to find
00:26the animal observe it and follow it around so big challenge for this study and something I've
00:32been working on for years trying to understand the behavior in this little frogs is putting tiny
00:37tracker tags on them their solution this tiny little tracker tags attached to tiny little waistbands
00:44they safely attached to the tiny frogs and they have to be small as the frogs are attaching them
00:48to are only two to four centimeters big the whole study is looking at the movements and hormone
00:53levels of three frog species specifically looking at their ability to navigate the jungle two of
00:58the three species are predominantly raised by their male parents with the study's conclusions
01:02challenging the long-held belief that rather than specialized adaptation for navigation in different
01:07sexes there was actually a hormonal component meaning sex hormones could have an impact on a
01:12creature's ability to navigate
