How do alligators interact with birds?
“The birds are protected from raccoons and other predators, and the alligators get food. Both partners appear to derive significant benefits from the relationship, which might enable them to exist in places they otherwise might not.” Also, the relationship between birds and alligators may affect where they can dwell.
Did alligators evolve from birds?
Since alligators descend from a common ancestor with dinosaurs, they can provide a useful evolutionary comparison to birds. (Despite their appearance, birds are more closely related to alligators than lizards are.)
Are alligators and chickens related?
Chickens seem to share commonalities with both mammals and reptiles, but it is commonly classified as something else: a fowl. By that logic, snakes, crocodiles, alligators, turtles and lizards – and even birds – are reptiles.
What are alligators closely related to?
Did you know? Alligators and their relatives are the last of the living reptiles that were closely related to dinosaurs, and their closest modern kin are birds. There is only one other alligator species, the Chinese alligator. Alligators and crocodiles are related.
Why do alligators not eat birds?
Wading birds contribute to the alligators’ diet when they give up a few chicks to protect many. But when raccoons and possums invade colonies, the birds abandon them because the mammals will eat every single egg and chick. Alligators become a necessary evil.
What birds help alligators?
Over time, a study released Wednesday says, egrets, herons, ibises and storks that nest on islands developed a strategy. They nestle on tree limbs near alligators, which chase and sometimes eat nest raiders. For that service, alligators demand a heavy price – some of the birds’ offspring. That’s right: child sacrifice.
Are birds afraid of alligators?
In a 2011 experiment from the University of Florida, researchers found that the birds even preferred to nest above fake alligators. “Raccoons are devastating for birds,” said Nell, now a research technician at the University of Georgia.
Is it true that alligators and birds are the same?
That hasn’t always been the case, though, and that’s what attracts Arkhat Abzhanov. Alligators and birds are part of the same larger group, called archosaurs, which has existed for 250 million years and which has given rise not only to birds and crocodilians, but also to dinosaurs.
Are there any alligators that are related to dinosaurs?
Yes, ancient species of alligators (and multiple species of crocodiles) lived at the same time as dinosaurs. Several species of the order Crocodilia that include Crocodiles and Alligators of the modern-day evolved during the Mesozoic era.
How are birds and crocodiles related to each other?
Birds are most closely related to crocodiles. To understand this, we should look at some history. The first groups of reptile-like animals evolved about 320 million years ago.
How are birds related to dinosaurs and reptiles?
Then, 65 million years ago there was a massive extinction event, and all dinosaurs were killed except for a single group of feathered dinosaurs. These evolved over the next 65 million years into modern birds. So birds aren’t just closely related to dinosaurs, they really are dinosaurs!

Why are alligators so easy to find in the wild?
This finding suggests that these birds seek out these alligators and that these alligators seek out these birds — the alligators are not too difficult to find, as they often lie conspicuously on land when basking, and loud, smelly bird colonies are equally easy for gators to find, Nell said.
What kind of bird nests above an alligator?
Birds Use Alligators As Bodyguards. For many species of birds, the greatest threat their chicks face are nest-attacking predators, such as raccoons and opossums. Previous research found that wading birds — such as storks, herons, egrets, ibises and spoonbills — often choose to nest above alligators.
Are birds related to dinosaurs?
The present scientific consensus is that birds are a group of maniraptoran theropod dinosaurs that originated during the Mesozoic Era. A close relationship between birds and dinosaurs was first proposed in the nineteenth century after the discovery of the primitive bird Archaeopteryx in Germany.
