Desert Migrations Threatened by Shifted Cactus Blooming Time

Ocotillos are blooming too soon, leaving migrating hummingbirds without food,
Desert Sun, October 1, 2018.


Ocotillo Cactus driven by climate change to bloom too early for migrating hummingbirds.

Traditional Bloom Timing

"...ocotillos bloomed in April and May, not in the dead of winter."

2007 Bloom Timing

Now, "...dozens of ocotillos blooming in January – months before migrating hummingbirds would arrive in the Coachella Valley."

"...Sonoran Desert shrubs, including ocotillo, began blooming nearly 40 days earlier than they did a century ago...(and)...ocotillos and other shrubs ended their bloom more than a month earlier than in previous decades. "

Change You Can Believe In

"...there would be disastrous consequences for most hummingbird species since all but one migrates through the Southwest and northern Mexico."


Massive Human Population Growth Destroying Everything...

The Hummers are Far from being Alone...
