It illustrates for you that BOTH genetics AND societal influences can alter gender identity.
No Joe, you can't draw that conclusion from a photo. Sorry. The have pictures of Bigfoot, still haven't been able to prove it without a shadow of doubt.
No one can say that that bird is saying to itself that if I change colors, I can now lay eggs. Nature has given these birds the ability to change colors for a reason. It could be to not fight with other males or to blend in with the female in order to breed. They didn't however make a cognitive choice to go from male to female because they thought they should have been female at birth. Common Joe you're smarter than this.
These are not "Cardinals". And do not "change color" during seasons.
M/F have completely different plumage.
Are you unable to read?
Plumage (from
Latin pluma 'feather') is a layer of
feathers that covers a
bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between
species and subspecies and may vary with age classes. Within species, there can be different colour
morphs. The placement of feathers on a bird is not haphazard, but rather emerge in organized, overlapping rows and groups, and these
feather tracts are known by standardized names.

Most birds
moult twice a year, resulting in a breeding or
nuptial plumage and a
basic plumage. Many
ducks and some other species such as the
red junglefowl have males wearing a bright nuptial plumage while breeding and a drab
eclipse plumage for some months afterward. The
painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the
juvenile plumage with an
auxiliary formative plumage; the second a month or so later giving the
formative plumage.
[3]
Abnormal plumages include a variety of conditions.
Albinism, total loss of colour, is rare, but partial loss of colours is more common. Some species are colour
polymorphic, having two or more colour variants. A few species have special types of polymorphism, as in the male
ruff which has an assortment of different colours around the head and neck in the breeding season only.
Hen feathering is an inherited plumage character in
domestic fowl controlled by a single gene.
Plumology (or
plumage science) is the name for the science that is associated with the study of feathers.
