Vulture
A vulture is a scavenging bird of prey that feeds mainly on carrion.
A vulture is a scavenging bird of prey that feeds mainly on carrion. There are 23 living species split into two groups—Old World vultures and New World vultures—that evolved similar traits independently.
What it is
Vultures are large birds with broad wings for soaring, bare heads and necks, and hooked bills for tearing flesh. They are divided into Old World vultures (family Accipitridae, found in Europe, Africa, and Asia) and New World vultures (family Cathartidae, found in the Americas). The two groups are not closely related, making them a classic example of convergent evolution.
Why it matters
Vultures are obligate scavengers that feed on carrion, helping to remove dead animals from the environment. This limits the spread of disease and keeps ecosystems cleaner. In Canada, turkey vultures range into southern parts of the country, making them relevant for wildlife observation and conservation.
Key details
Vultures occur across tropical and temperate regions worldwide, but are absent from Antarctica and Australia. They have 23 extant species, including condors. Their scavenging role is ecologically vital, and their independent evolution in two lineages is a well-known example of convergent evolution.
In short
- Vultures are scavenging birds that eat carrion, helping prevent disease spread.
- They split into Old World and New World groups, which evolved similar traits separately.
- There are 23 living species, found across Europe, Africa, Asia, and the Americas.
- Turkey vultures reach southern Canada, linking them to Canadian wildlife.
Turkey vultures range north into southern Canada, making vultures relevant to Canadian readers through wildlife observation and conservation.
