The Reddish Egret (Egretta rufescens) presents a fascinating case of both age-related color change and dimorphism within the same species. Young egrets of both color morphs begin life with grayish-brown plumage and bluish bills with dark tips, making juvenile identification challenging. As they mature, they develop into either the dark morph with distinctive reddish head and neck plumage.
Ask Kenn: What's Up With Bird Color Morphs and Phases? In some species, many adults wear different color patterns from others. Kenn Kaufman explains the phenomenon, and the lingo to describe it.
What are Avian Color Morphs? At its most basic, a color morph is a distinct plumage variation within a bird species. These variations aren't due to age, sex (sexual dimorphism), seasonal plumage changes (breeding vs. non-breeding plumage), or albinism/leucism (which affect pigment production more broadly).
Melanism causes birds to have an excess of dark pigmentation and is generally caused by a genetic mutation, but can also be a result of certain diets. Some species have a naturally occurring melanic form (or "morph"), such as the Red.

Post-doc Chima Nwaogu analysed the influence of weather conditions on timing of egg-laying and breeding success on Black Sparrowhawk morphs. His results show that interactions between sex, timing of breeding and rainfall may underlie the maintenance of colour polymorphism and the increasing frequency of light morph Black Sparrowhawks in Cape Town.

On rare occasions, a colour abnormality may turn out to be advantageous in the wild. In the past, white feathers must have enhanced the survival of a parrot in Australia, allowing it to live longer than others of its kind and to pass on its genes.

Therefore, daily activity patterns of different morphs may be an important factor in explaining the maintenance of colour polymorphism in birds. Different morphs may vary in success in different habitats or in the same habitat under different light conditions, because of variation in foraging efficiency or survival, because of hunting or.
About 40% of bird species display multiple color morphs, giving you nature's best wardrobe variety show. You'll find these different forms because genetic mutations create alternative appearances that help birds adapt to changing environments, attract mates, or survive predation pressures more effectively.

A morph, or color phase, happens when birds of the same species regularly develop more than one plumage color. The morph plumage could be any color: white, red, blue, gray, brown, etc. One of the word's most common birds comes in a whole assortment of colors, yet I'd be willing to bet most people haven't noticed. Want to guess what that.
