The story began 70 million years ago when dinosaurs roamed the Earth, and the first owls appeared. Life was challenging, with huge lizards and other predators competing for resources. A meteorite extinction event led to hunger, but owls adapted and thrived. This peaceful existence lasted until 36 million years ago, when eagles appeared, becoming the perfect rivals for owls.
The rivalry between owls and eagles has been ongoing for 36 million years, with both species competing for resources, territory, and survival. Owls have adapted to this competition by becoming nocturnal predators, while eagles have developed powerful talons and sharp eyesight.
Despite their differences, both species have evolved to coexist, with owls stealing eagles' nests and eagles fighting back. Crows have also entered the picture, behaving like natural enemies towards owls and sometimes killing them.
However, with climate change, the populations of both species are declining rapidly, and the war between them may soon become irrelevant. According to a study, North America has lost 3 billion birds between 1970 and 2017, and 389 species are at risk of extinction in the near future.
Here are the key facts from the text:
1. The story of owls and eagles began 70 million years ago.
2. The first owls appeared while the last dinosaurs were still roaming the planet.
3. A meteorite extinction event occurred, causing hunger and prompting owls to adapt.
4. Owls and eagles have been rivals for 36 million years.
5. Eagles appeared 36 million years ago, ending the peaceful life of owls.
6. Owls and eagles fight each other during the day and night, sharing resources and evolving together.
7. They sometimes kill and eat each other.
8. Owls destroy eagle chicks and nests, and vice versa.
9. The fight between owls and eagles has become a real war.
10. Owls have adapted to their environment by becoming nocturnal predators.
11. Many rodents are active at night, allowing owls to hunt safely without fear of competition from eagles.
12. Owls have better maneuverability but don't make long flights, while eagles have incredible eyesight.
13. The largest eagle, the giant piccardo, can reach 105 centimeters in length.
14. The largest owl, the blackstone owl, reaches 70 centimeters in length.
15. Owls usually eat small rodents, hares, squirrels, insects, fish, and frogs.
16. Eagles eat everything from fish and rodents to cows, sheep, parrots, and turtles.
17. Owls and eagles share the same niche, leading to competition and conflict.
18. Owls may have evolved to become nocturnal to avoid competition with eagles.
19. Some researchers believe that owls were larger in ancient times but decreased in size over time.
20. The avian skeleton is too thin to be found as a fossil, making it difficult to study owl evolution.
21. A fossil of an owl that lived 55 million years ago was found in Wyoming, with deadly talons.
22. Modern owls prefer to use their beaks, unlike their ancestors.
23. Owls can have up to three or four chicks, while eagles usually incubate one or two chicks.
24. Owls are found almost everywhere, while eagles are more demanding and settle mainly in mountainous regions.
25. Crows are natural enemies of owls and will attack them, sometimes to death.
26. Crows will also chase eagles in entire flocks.
27. The confrontation between eagles and owls is much older and more noble than other bird conflicts.
28. Climate change could cause a catastrophe on a planetary scale, affecting bird populations.
29. Minor changes in temperature could be fatal for birds, and their populations are declining rapidly.
30. North America has lost some 3 billion birds between 1970 and 2017 and is at risk of losing another 389 species.
31. The smallest species, such as blackbirds and sparrows, are the most affected by climate change.
