A new tracker built for monarch butterflies weighs about as much as a single grain of rice, and it doesn't carry a battery at all.
The BlūMorpho, 3.5 centimeters long, runs on harvested energy instead, light, motion, whatever's around it to power the signal. Earlier wildlife trackers in that weight class usually force a tradeoff: strap on enough battery to matter, and you've also strapped on enough weight to change how the animal actually flies.
I think about that tradeoff every time a client site ships a dashboard with twelve analytics scripts competing for the same page load. Heatmaps, two ad pixels, a chat widget, three A/B testing tools, each one individually "lightweight," none of them ever scheduled for removal once the campaign that needed them ends.
The data's worth having. What's rarely worth it is the weight it quietly adds to the thing being measured, which is exactly what skews the measurement.
What's the one tracking script on your site right now that's been there so long nobody remembers which test it was for?
