Wing projection: the part of the WINGS which extends beyond the TAIL tip when
the bird is perched (i.e. for a long-winged bird)
Tail projection: the part of the TAIL which extends beyond the WING tip when
the bird is perched (i.e. for a long-tailed bird)

Subject: Re: [Birding-Aus] Question: 'Wing Projection' or 'Wing Point'?
In "Sibley's Birding Basics", Sibley describes primary projection as extension
of the primary tips past the tertials. A couple of paragraphs later, he
describes this measurement for which you want a term, but gives it no name.
This is in a 13 page chapter just on wing structure, so you'd think he'd
mention the term if there was one.
But I've heard the term "tail projection", and assumed it meant wing tip to
tail tip. What's the definition of that?
