Only one of the three species of Vultures found in North America have been spotted in Nevada, the Turkey Vulture.
Vultures have some disgusting habits such as urinating on themselves to keep cool, only eating bacteria-laden dead animals which they stick their bald heads into to tear the flesh, and vomiting to escape from predators.
However, these disgusting habits are in fact brilliant adaptations that help the vultures to survive and clean up the environment for us.
Vultures urinating on themselves not only help to keep them cool but is also thought to kill the bacteria on their legs that they pick up when walking through the dead animals.
Vultures’ bald heads stop their feathers from getting congealed with blood from having to stick their heads inside carcasses to get to the flesh. Their legs are weak, and their talons are not strong enough to grab and hold the food, so they just use their powerful beaks to tear and rip.
The stomach acid of vultures is extremely strong, and this makes them one of the few animals that can safely eat the bacteria-laden carcasses that would potentially harm or kill other species, so getting rid of this harmful bacteria from the environment. Bacteria such as botulism and anthrax.
Vomiting to get away from predators is thought to enable them to be lighter to take off, as they gorge themselves so become very heavy, and it may provide a distraction.
Vultures lack vocal organs to make songs, but they can make deep hisses or grunts, especially when alarmed or jostling for a space at a carcass.

This guide will help you identify the types of Vultures spotted in Nevada according to avibase and uses data collected from bird watchers on ebird to give real information about when these birds can be spotted.
Species of Vulture in Nevada:
1. Turkey Vulture
Turkey Vultures can be found in Nevada during the breeding season and occur in 11% of summer checklists submitted by bird watchers for the state. They are usually spotted from February to October, but a few hang around all year.
Turkey Vultures are aptly named. They do look like turkeys with their big, bald, red heads and upper necks and brownish-black bodies. However, they are larger than turkeys, and when they’re in flight, their broad wings are slightly raised and make a “V”.
Under their wings, they have gray coloring, making it seem like they’re two-toned. Their eyes are dark brown, and their bills are light-colored.
There are a total of 6 subspecies of Turkey Vultures, and three of them are in North America, which is why they are sometimes classified as “Northern” Turkey Vultures. There are only minor differences among them, mainly tail and wing proportions and color in the underwing feathers.
- Cathartes aura
- Length: 26 – 32 in (66 – 81 cm)
- Weight: 51.2 oz (1451 g)
- Wingspan: 68 – 72 in (173 – 183 cm)
You can find Turkey Vultures in a wide range of habitats, but the most common is open and semi-open areas next to woodlands. They need open areas, like grasslands, shrublands, deserts, and wetlands for foraging. They also need forests with high trees for nesting and roosting, and they need middle to high elevations, like hills and mountainous areas, to give them a height advantage for taking flight.
Sometimes, they will also venture into farmlands or pasturelands for foraging and roosting. Human-made structures are also taken over by them when they’re in urban areas, but only if they can’t find their preferred habitats.
Turkey Vultures’ main source of food is carrion or recently dead or decaying animals as long as it hasn’t decayed too much. They may feed on roadkill and washed-up fish and may even kill small or weak animals.
Turkey Vultures calls: They can only make a raspy hissing sound but are usually silent.
Nests of Turkey Vultures are often found in sheltered areas, like crevices in cliffs and old buildings. They may also use hollow trees or logs and dense thickets. However, they don’t actually build nests. Instead, the female lays one to three eggs on the ground at the nesting site. Incubation takes around thirty-eight to forty-one days and is accomplished by both parents.
Fun Facts: The sense of smell of Turkey Vultures is quite strong, and they’re able to detect odors of decaying or dead animals on the ground from great distances.
When Turkey Vultures are threatened or aggravated, they will vomit to provide a distraction and fly away. They may even pretend to be dead.
