New Annotation: Evidence of Presence

When I annotated my own small collection of non-organism observations, eggshell and nest were common among them.
Personally I would favour “home” for nest as it is easily translatable and removes the need for dozens of home types in the list.

While we wait for “eggshell” to be covered, through the excellent process being conducted in this thread, does anyone have a suggested annotation? Mine are usually a single broken shell on the ground. Occasionally an unbroken one…presumably that is organism, life stage=egg? And, if cold, dead?

I would say marking any eggs / egg fragments as “Organism”, “Life Stage: Egg” and “Dead or Alive: Cannot Be Determined” should be sufficient while we wait for more annotation options.

Thanks, will do.

Technically, isn’t a molt made of dead cells that were once alive? Like the dead skin we constantly shed?

But organism itself is not dead, so they should stay separated, plus it’s an interesting observation different than just dead body.


I think that covers every dead cellular organism or part of organism, including dead skin cells:)

Regarding Alive or Dead - remember that an observation records an encounter with an organism or recent evidence of an organism in a time and place. If you came across a snake molt on July 6th at 4:05 pm, I would argue that you don’t know whether the actual snake that left the molt is alive or dead on July 6th at 4:05 pm, so the correct value would be Cannot be determined..


So that is the same as eggshells, life or death Cannot be determined.
And nests or other homes.

Depending if shells are from hatched egg or eaten, with the scond it’s safe to say it’s dead.

How is ‘cannot be determined’ useful? As opposed to no annotation?

Unless the eaten egg is considered evidence of an ovipositing female in which case the subject organism could be alive. But I’m obviously overthinking all this. ;-)

That is how I always see a bird’s egg, actually…as evidence of breeding, and sometimes of hatching if a broken shell is fresh and clean, and sometimes as evidence of likely predation or nest stealing by another bird

I find it useful primarily because it removes sightings from the pool of unannotated sightings
