Why crows haven't invented stretchers to carry fellow crows to safety? Making a stretcher doesn't look more complicated than building a nest.

- withinboredom 6y agoA crow can carry about 1.5 lbs in flight. A crow weighs at most 4.5 lbs. Let's assume a stretcher that can carry a crow by more than one crow to weigh another 1-2 lbs. At most, the total payload would be ~5 lbs which requires at least 4 crows. I don't think that kind of coordination is possible with that kind of turbulence in such close quarters. So why bother?
