Calif. Audubon: Putting birders to work to build a case for climate [swindle] action | Grist
....But this new work in the area of climate change is different. Once we combine these two technologies—the decidely low-tech counting of birds and the high-tech computer modeling and mapping—we make some surprising discoveries that wouldn’t have been possible with either on their own.Yellow-billed Magpie - Whatbird.com
Perhaps the most notable of these is the fact that while the consequences of inaction are still great, we have a startling amount of power to lessen the impacts of global warming on our wildlife and natural landscapes. While climate change could cause significant range declines in up to a third of California’s birds, these impacts can be greatly lessened for many species if we take immediate action to reduce greenhouse gas emissions.
Take, for instance, the Yellow-billed Magpie, a highly social bird that lives only in California’s Central Valley and Coast Ranges. This species could lose as much as 75 percent of its range under the worst emissions scenarios (a loss that in combination with other pressures such as habitat loss due to development would likely result in the bird’s extinction). However, the magpie could lose as little as 9 percent of its range if we take extra strong measures to reduce greenhouse gasses in our atmosphere.
The Yellow-billed Magpie has a fairly large range reaching up to generally 83,000 square kilometers. This bird can be found in its native United States where it appears in forests, pastureland, arable regions and even rural garden. The global population of this species is estimated to be around 180,000 individual birds. Currently, it is not believed that the population trends for this species will soon approach the minimum levels that could suggest a potential decline in population. Due to this, population trends for the Yellow-billed Magpie have a present evaluation level of Least Concern.
