This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

Given their range, I wonder if their bulkiness functions to reduce their surface area to volume ratio. Since small birds need to eat a shittone of food compared to their body weight.

Probably. Also, it likely helps that they are omnivorous, and they chonk up for the winter. Some also migrate relatively short distances (blue on map).
