We've been asked if we're offering monarch tagging this year, & unfortunately we just don't have time. We hope to find time to offer it again next fall as a pop-up program.
However, Leah was given the amazing opportunity to work with connections from & to tag monarchs in a brand new way- radio tags!
sticker tags have been helpful for many years & are accessible to individuals & will continue to be an important part of monarch research & conservation. uses super lightweight radio trackers, Motus towers, & bluetooth technology found in everyday devices to get a more detailed picture of monarch migration.
Yesterday, Leah helped catch wild monarchs, which were then weighed, sexed, tested for OE, & measured for wing length & condition. Seven of the healthiest, largest individuals were chosen to be fitted with fancy new 'backpacks' designed not to interfere with their flight. Leah glued a tiny solar-powered radio transmitter to a heavyweight female monarch (weighing in at a whopping .8 grams), let her rest & replenish her fuel, then released her back into the wild with the others affixed with their new conservation-styled accessories.
Each monarch's information was added to the Project Monarch portal, & now every time these monarch fly near a Motus tracking tower or other bluetooth device, their presence is detected & shared within the project. The photo shows the monarch Leah tagged just before she flew into the air & out of sight. She was already detected 87 times in the last 24 hours(!), & appears to be currently staying within the park boundary where she was tagged.
Though these bluetooth-enabled trackers are quite expensive so not accessible to most people, anyone can download the Project Monarch app for free & search for tagged monarchs in North America. (Leah's butterfly's 'name' is LEAH-TRPD-MN26-005 if you want to help keep an eye on her in the app.) But the coolest thing is that anyone who has a bluetooth device is helping track every monarch (& likely other small animals) just by having their bluetooth turned on... your cell phone could help detect a monarch up to 200m away!!
What an incredible experience & we wish these monarchs luck in their hopefully long journey ahead!
