Light Pollution from Skyglow Changes Bird Behavior

Animals evolved for millions of years to live under naturally dark skies. But in the last few decades, humanity has directed more and more lighting into the sky, creating light pollution that has been proven to confuse many animal species. A new study looked at the behavior of birds that feed at dawn and dusk and the impact of light pollution on their behavior. The researchers found that the effect is complicated, with skyglow creating brighter conditions under overcast skies compared to regions without light pollution, and changed the birds' choices for when to fly.

I may have found an alternative solution to my blog's commenting system! 😺

The synchronization of comments from my Mastodon account. It's something I tried and abandoned, but I'm giving it another try after reading your comments. Well, I explain more on the blog and also share the source code:

How can astronomers know exactly how hot stars are? You can guess from their colors, but to get a precise measurement, you have to look at their spectra.

We spread out the light from the stars into a rainbow-like spectrum and look for patterns of lines, made by different elements and molecules in the star's outer layers. The presence or absence of lines tells you the precise temperature.

All latitude bands observed anomalous warmth in June 2023. The largest positive departure were near the Antarctic Peninsula.

Plot shows zonal-mean surface air temperature anomalies (1951-1980 baseline), where latitude = x-axis (not scaled by distance). Data from GISTEMPv4 at data.giss.nasa.gov/gistemp/.

Shout out to @radiofreefedi for introducing me to so many awesome new Fedi #artists in so many genres. I usually can only listen for 20 minutes at a time as I’m doing chores, and it’s great to hear such a wide variety of #music that I just couldn’t get from a commercial station that only plays 2-3 genres, or even streaming algorithms that still can’t understand that I crave novelty, not just more of the same. And no ads filling up my precious time! #FediMusic

Tune in at radiofreefedi.net/

Good night/morning Americas, morning Europe, afternoon Asia, evening Aussie and hullo NZ.

We are having a listen to #radioFreeFedi main channel and have the chat open at

party.radiofreefedi.net

in case whatever stage of your weekend could use some friendly chat and some fun tune discovery.

We can talk about some of the new things coming. Maybe some artists will stop through and say hi. Maybe we can trade secrets for the softest ever shirt laundering. Or just hang and listen. All welcome.

July in the #Arctic now is a very different place than it was only a few decades ago - just check out the changes in the average sea ice thickness....
