Hi,
I am often impressed by the knowledge that can be found in the bird ID section, it's a great source of learning.
But sometimes I wonder how much of the things I learn there are actually useful in the field. For example in this thread http://www.birdforum.net/showthread.php?t=262877 the ID was clinched with the conclusion
I myself would certainly not be able to see these details on warblers in the field, even with primary projection I usually have a very hard time to see enough to be useful for ID. Obviously in the field there are other things that help, like call, behaviour, habitat.
So my question is: do the pros among you actually use things like wing formula and primary projection for ID in the field (on small birds), or is this something that can only be reasonably used on photos or birds in the hand?
Cheers,

Emargination on P3 falls roughly between the tip of P7 and P8. A very strong pointer towards Marsh warbler.
