BIRDS CLIMATE MIGRATION TIMING

Shifting Seasons Shifting Bird Migrations, (& Everything Else...)

Birds' Seasonal Migrations Shift Earlier as Climate Changes, new research shows,
University of Massachusetts Amherst, December 16, 2019.

MAIN POINTS

Continental Scale
"...one of the first studies to examine climate change impact on the timing of bird migration on a continental scale..."

24 Years of Nocturnal Migration
"...analyzed 24 years of radar data from the National Oceanic and Atmospheric Administration (NOAA) for this study of nocturnal bird migration."

Lotsa Bird Migration Data
"...observed nighttime migratory behaviors of hundreds of species representing billions of birds, as "critically important" to understanding and learning more answers about shifting migration patterns."

Changing with Warming
"...the greatest changes in migration timing occurring in the regions warming most rapidly. Timing shifts were less apparent in fall, they add."

Shifting Spring Migration
"...spring migrants were likely to pass certain stops earlier now than they would have 20 years ago"

Fall Migration Stability
"...the lack of change in fall migration patterns was a little surprising, though migration also tends to be a "little bit messier" during those months."

"To see changes in timing at continental scales is truly impressive, especially considering the diversity of behaviors and strategies used by the many species the radars capture."

Why Seasonal Timing Important
"...because the birds rely on food and other resources as they travel. Under climate change, the timing of blooming vegetation or emergence of insects may be out of sync with the passage of migratory birds. They say even subtle shifts could have negative consequences for the health of migratory birds."

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

I NEED HELP!
If you feel these efforts are valuable, I'm cordially inviting you to support them, here:

 

 

I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
