Interesting test. However, the answer to question 23 is INCORRECT! You can age most gamebirds using the 9 and 10th primary feathers, except for PHEASANTS. Below is an except from one of many papers on the subject.
Most gallinaceous birds can be identified as juveniles or adults using the outermost primaries (P9 and P10)
which are retained until after the first breeding season and are often identifiable by colour and wear. The
pheasant Phasianus colchicus, however, moults all ten primary feathers during its post-juvenile moult so alternative
techniques are required
