Why do turkeys have bumps on their head?
The fleshy bumps on the turkey’s head and neck are called caruncles. Both male and female wild turkeys have both wattles and snoods, but they are much more prominent and noticeable in males, called toms. This is helpful during mating season, when extra blood rushes to the wattle, giving it a bright scarlet color.
What does it mean when a turkeys head changes color?
Turkeys’ heads change color to express their emotions. Berkeley scientists have used this adaptation to create a biosensor for germs, toxins, and TNT. Turkeys can change the color of the skin on their heads from red to blue to white, depending on whether they are calm or excited.
What are turkey Spurs?
A spur is a long talon or claw on the back of a turkey’s leg, about 2 inches above the foot. Spurs are made of smooth, shiny keratin, and range in color from black, gray or pink.

What diseases can turkeys get?
Though avian pox is probably the most common disease affecting wild turkeys, it is not a major threat to the population. Other viral diseases that have been noted in wild turkeys include western equine encephalitis, St. Louis encephalitis and eastern equine encephalitis.
What causes diarrhea in turkeys?
Diarrhoea. Diarrhoea in turkeys can be caused by a number of harmful agents including bacteria, viruses (such as haemorrhagic enteritis virus) and coccidiosis.
Why do turkeys heads turn purple?
They change color. Well, the heads and necks of males do. Naturally a grayish blue, their skin can turn a deep red-purple when they’re feeling feisty (think mating/fighting). “During breeding season, their heads could be red all week!”
Do turkeys shed their spurs?

How long do wild turkey spurs get?

What does it mean when a turkey gobbles?

It’s the same scattering effect that makes the sky appear blue but sunsets yellow or red. It’s also the reason that blood vessels appear blue beneath pale skin, even though the blood inside them is red.
Can a Turkey’s color-changing technique detect toxins?
In a new study released today in Nature Communications, a research team at the University of California, Berkeley, led by Seung-Wuk Lee, explains how they have developed a synthetic toxin sensor based on the turkey’s color-changing technique.
