1.Feathers show how healthy they are.
2.The birds skin isn’t the same color as their feathers.
3.As the bird gets older its color changes.
4.They get their color from its liver.
5.You can tell how old they are by their feathers.

The cartenoids that give the common crossbill its red color are produced in the liver, not the skin. Carotenoids have important functions like antioxidant, immunomodulating, and photoprotectant functions. Carteniod pigments give many bird species the red, orange, and yellow coloration. The cartenoid red coloration signals the nutritional and health status of the bird and its ability to lacate high quality resources. Adult males have cartenoid-based coloration on the throat, chest, and rump.

Birds get there feathers from their liver and not there skin. Also by a baby birds color you can tell if it’s healthy. When a bird gets older their color might change. Carotenoid pigments are also used by many birds as colorants, and are responsible for most of their red, orange and yellow colors.

According to Esther del Val the birds get there red coloration from the liver not the skin.Carotenoids have important physiological functions like antioxidant, immunomodulating, and photoprotectant properties. they say that as the bird gets older that there colors may change and coloration is based on the health of the bird.

Where do birds get their red feathers from? According to Esther del Val, from the National History Museum in Barcelona, Spain, and her team, the red carotenoids that give the common crossbill (Loxia curvirostra) its red coloration are produced in the liver, not the skin, as previously thought.

Their findings, published online in Springer’s journal Naturwissenschaften, have implications for understanding the evolution of color signaling in bird species.

1. Birds feathers are produced from their liver, not the skin.
2. As the bird gets older, its feather color changes.
3. Coloration is based on the health of the bird.
4. They examined the liver, blood, skin, and feathers of 7 crossbills.
5. They coordinate red, yellow, and orange coordinations.

1. Carotenoids have important physiological functions such as antioxidant and immunomodulating.
2. They coordinate on red, yellow, and orange coordinations.
3. They exaimined the liver, blood, skin and feathers of seven crossbills.
4. They examined it’s color coordination.
5. And found out the key to comprehend the different evolutionary pathways involved in color signaling.

1. the color of a birds feather was made by the liver and not from the skin.
2. when the carotenoid pigments are transforming it takes place durectly in the follicles during the growth of its feathers.
3. There are many funtions of a carotenoid including; antioxodents, immunomodulating, and photoprocent properties.
4. Health status and nutrition is signaled by the coloration of birds.
5. The liver is the main site of carotenoids body at which coloration happens.

* researchers examined the liver skin and feathers

* their color soon change

* birds get their color from their liver

*Del val was the researcher

* The bird skin is rerd from the liver
