@birdsarah That third picture

[karhutar@mastodon.social]

@birdsarah it's not a very dignified posture on the scales

@birdsarah hm sorry but can you explain a bit more about the method to weigh these smol birbs, that looks so funny
What's a film roll cup?

[drjlecter@beige.party]

@stragu back before most photography was digital, you had to put blank film rolls into your camera which you had to send in to companies developing the film roll into actual photos. These rolls came in these tiny cute plastic cups which were very useful to store small stuff once the photos were developed. I still have some ancient ones around to store seeds for example @birdsarah

@birdsarah it's honestly my favorite thing that the apparent offical technique to weigh birds is just "put that little fool into a tube facedown"

@birdsarah The loud, RAUCOUS laughter this startled out me, oh my God. People are looking at me from across the quad.

@birdsarah into the bird tube!

@stragu @birdsarah I always heard them called "film canisters"
