Climate Change Threatens Bird Migrations, Habitats In San Diego County
Monday, April 2, 2018

“I would say that every species in San Diego County could be threatened by climate change, said Phil Unitt, curator of birds and mammals at the San Diego Natural History Museum.
“Each species is going to be its own really complex story,” Unitt explained, as he walked along a path in the San Diego National Wildlife Refuge, using his special chirping call to attract nearby birds.
Unitt said annual migration patterns are being disrupted by rising temperatures, causing some species to seek new habitats that are wetter and cooler.
“Species like the house wren and the Cassin’s kingbird that aren’t migrating south in the numbers that they did previously,” Unitt said.
If Greens are so worried about migratory birds, maybe they should have objected more when their fellow travellers went and built loads of bird choppers, some of which allegedly exact an excruciating toll on birds and bats.
As if the bird choppers weren’t enough, other greens went and built what are in my opinion bird versions of the death star out in the desert. The locals call birds “streamers”, because of the smoke trail they leave when they fly through the solar concentrator hotspots – an average of one “streamer” every two minutes, according to Federal Investigators. If the one bird every two minutes estimate is correct, that accounts for a quarter of a million dead birds per year per concentrator – surely enough to put an observable dent in local bird numbers.
The video below is a rather sad encounter between a bird and a wind turbine, from which the image above was taken.
