Behaviour of Attraction
Males and females of many bird species have different plumage
(feather) coloring, a phenomenon known as sexual dimorphism. It's worth noting,
however, that not all bird species exhibit this attribute, and even among those
that do, there can be exceptions and variances.
Males and females in some animals have distinctly varied
colors, making it relatively easier to discern between the sexes based just on
color. Male ducks (drakes) in many ducks, for example, have brilliant and
colorful plumage, whilst female ducks (hens) have more subdued and concealed
colors.
Other species' changes may be more subtle, such as slightly
different color tones, patterns, or markings. In certain situations, the
variations may be seen only under certain lighting circumstances or during
certain times of year, like as during the breeding season.
However, there are several bird species whose males and
females have similar or identical plumage, making sex determination difficult
or impossible based merely on color. Other factors like as size, form,
behavior, vocalizations, and physical traits such as crests or wattles may be
utilized to discriminate between males and females in these circumstances.
It's worth noting that immature birds may have different
plumage than adults, and certain species exhibit "sequential
hermaphroditism," in which an individual bird may change sex throughout
its life
In conclusion, while plumage color can convey information
about a bird's sex in some species, it is not a perfect approach for
distinguishing the sex of all birds. Additional characteristics and
observations are frequently required to correctly determine a bird's sex.
