A dawn chorus of birdsong makes clear, birds respond to light.

Now scientists who used the total solar eclipse of April 2024 as a backdrop say light may be the most important cue for birds.

Observing them when it was lights out midday, some species seemed unaffected.

But study co-author Kimberly Rosevall at Indiana University told the science podcast Most Wild.

Supermoons happen three or four times a year, but this first supermoon of 2025 ushers in a trio in the last three months of the year.

It happens because the moon's 27-day orbit of Earth is not in a perfect circle, but more like an oval.

So when a full moon coincides with its closest approach to Earth, called the perigee, about 225,000 miles away, that's a supermoon.

It looks up to 14% bigger and 30% brighter, and does more than dazzle.

The proximity can cause higher tides than usual.

The name supermoon was coined in 1979 and is seeing a star turn in the internet age, periodically becoming a trending term.
