Ageing and sexing details:
ATY males
have black moustaches and deep red irises. The extent of red in the
crown should not be used for sexing.

Primary coverts are an irregular mix of dark brown (fresh),
brown, and very pale brown feathers OR are uniformly dark brown. The
secondaries are either uniformly adult with fresh tertials OR have 1-4
retained adult feathers (not symmetrically in both wings), contrasting
only slightly with the replaced feathers. ATYs with isolated, retained
juvenal primary coverts or with 3 generations of primary coverts
sequentially replaced might be reliably aged 4Y, but more study is
needed.

Consecutive outer
1-5 primary coverts are dark brown and fresh. All other retained primary
coverts are pale brown and abraded. In the photo below, the outer 2
primary coverts have been replaced and contrast with the retained inner
coverts. The secondaries are either uniformly adult OR sometimes with
1-4 retained juvenal feathers (symmetrically in both wings), contrasting
markedly with the rest of the wing. Some intermediates may occur that
are extremely difficult to age. These should be aged ASY. The third example below is of a Red-shafted (western) Flicker.

SY males have black
moustaches and have gray/brown irises through January. The extent of
red in the crown should not be used for sexing.
Primary coverts are paler brown than the rest of the wing.
Caution: fresh fall HYs can resemble ASYs with uniform secondaries and
primary coverts. Look for retention of juvenal characteristics through
October: a larger, rounded p10.
