While in Tanzania, I was able to identify 72 new species of birds for my life list, bringing my life total up to 404 species. I'm sure the number would have been higher if I had had a birding guide or even just another interested birder on the trip. Nobody wants to wait for a bird nerd while they are hiking and the nerd is trying to flush out a bird it hears chirping in a bramble. So it was keep up or get left behind. Several of the identifications were made after I got home. I would take pictures on the go to look at later for identifying them.
