In the spring, Rufous Hummingbirds journey from Mexico to the northwest U.S., some as far north as Alaska! That’s almost 1000 miles one way for a bird measuring just under four inches beak to tail, making this the longest migration of any bird relative to body length. Not long after arriving, they bulk up on nectar and bugs for the scenic return trip over the Rocky Mountains.

Views: Conflicts In The Deep Ocean (4K Video)
The deep sea is rife with competition and conflict. Deep sea biodiversity relies on the scattered organisms interacting in order to survive, whether they’re working together in symbiosis, scavenging, being predated, or parasitising a host animal. But there is one ecological interaction that does more than any other to influence organisms to change and diversify, and thus plays an important role in the success of deep sea communities. The limited resources mean only a small number of niches can exist. Thus, there is greater competition between different species trying to fill the same niches. This explains why the deep sea has so much competition, for animals must share the ecosystem with other competing species all trying to consume the same limited resources.

Seabirds: Scientists Save Black-Footed Albatross From Rising Sea Levels
Most black-footed albatross nest on sandy beaches in Hawaii—but rising sea levels threaten their eggs and chicks. Researchers in Mexico and the United States came up with a way to save these birds: having young albatross hatch and imprint on an island 6000 kilometers away with higher ground. Watch to see the journey of these black-footed albatross. Read the story: https://www.sciencemag.org/news/2021/…
