I am looking for a term to use to refer to the extension of primary tips past the tip of the tail.
Preferably the term should not cause any confusion with the extension of primary tips past the tertials.
I am aware that “primary projection” is commonly used by many birders to describe both extension of the primary tips past the tertials and extension of the primary tips past the tip of the tail but this has been discussed on BirdingAus in the past and has been considered by some learned birders to be wrong. That is, wrong when used to describe the extension of the primary tips past the tip of the tail. One term for the extension of the primary tips past the tip of the tail suggested in that discussion was “wing projection”. I have since discovered the term “wing point” to describe this condition in “The Shorebird Guide”, O’brien, Crossley and Karlson, 2006. In the Glossary of that publication “Wing Point” is described as “The degree to which primaries project beyond the tail”. This looks like what I want but I have been unable to find this term being used in any other of my bird books. Searching on Google only brings up subjects on real estate in the USA and political discussions.
I ask members of the list to please share with me their ideas on which term is best used to describe the extension of the primary tips past the tip of the tail.
Personally I don’t favour “primary projection” but would be happy to use whichever of the terms “wing projection” or “wing point” is favoured by a majority. My aim is to use a term which at least most birders can understand and accept. I would, of course, be interested to see if there is another term which is commonly used and accepted….and is correct.
