But does the value of a particular trip come from the number of birds seen, viewing a particular species, seeing an endangered species, catching a glimpse of a rarity, adding a lifer, or something else? I emailed the authors and asked about their research and their use of eBird data. Birders derive “value” from birding.

And the term is ‘non-reversed size dimorphism.’).

The Telomere does not contain useful genetic information, but rater, acts as a buffer. Research done quite a while back suggests that this is adaptive.
