Who Will Come to Your Bird Feeder in 2075?

07.11.2014

The distribution of birds in the United States today will probably look very different in 60 years as a result of climate, land use and land cover changes.

Anew U.S. Geological Survey study predicts where 50 bird species will breed, feed and live in the conterminous U.S. by 2075. While some types of birds, like the Baird’s sparrow, will likely lose a significant amount of their current U.S. range, other ranges could nearly double. Human activity will drive many of these shifts. The study was published today in the journal PLOS ONE.

"Habitat loss is a strong predictor of bird extinction at local and regional scales," said Terry Sohl, a USGS scientist and the author of the report. "Shifts in species’ ranges over the next several decades will be more dramatic for some bird species than others."

Climate change will cause average temperatures to change by three degrees to seven degrees Fahrenheit by 2075, depending upon scenario and location within the conterminous U.S. Temperature increases will drive breeding ranges for many species to the north. Precipitation will increase in some regions and decline in others, resulting in substantial impacts on local and regional habitat.

Habitats for birds currently breeding in the far southern U.S., such as the desert-dwelling Gambel’s quail and cactus wren, will expand greatly by 2075 in the conterminous U.S. as a warming climate moves the overall range to the north. The chestnut-collared longspur, sharp-tailed grouse and gray partridge could all lose over 25 percent of their suitable breeding range in the northern U.S. as climate becomes more suitable in Canada for these species. The Baird’s sparrow may lose almost all of its current U.S. range.

Landscape changes resulting largely from human activity, including land use and land cover changes, will also significantly affect future U.S. bird distributions. The effects of landscape change will be more scattered, with very high loss of habitat at local and regional scales.

"Changing landscape patterns such as deforestation and urban growth are likely to have at least as large of an impact on future bird ranges as climate change for many species," Sohl said.

The new study used climate and landscape data to create and compare U.S. distribution maps of 50 bird species in 2001 and 2075. The maps for each species are available online.

The species that will either gain or lose more than 20 percent of their conterminous U.S. ranges as compared to 2001 are:

  • Gambel’s quail: 61.8 percent gain
  • Cactus wren: 54.1 percent gain
  • Scissor-tailed flycatcher: 46.4 percent gain
  • Gray vireo: 44.9 percent gain
  • Painted bunting: 38.5 percent gain
  • Anna’s hummingbird: 27.2 percent gain
  • Black-capped chickadee: 21 percent loss
  • Ferruginous hawk: 21.2 percent loss
  • Sora: 22.8 percent loss
  • Northern harrier: 24.7 percent loss
  • Bobolink: 24.9 percent loss
  • Short-eared owl: 26.2 percent loss
  • Vesper sparrow: 26.4 percent loss
  • Savannah sparrow: 27.2 percent loss
  • Sedge wren: 29 percent loss
  • Gray partridge: 35.6 percent loss
  • Sharp-tailed grouse: 44.8 percent loss
  • Chestnut-collared longspur: 54.1 percent loss
  • Baird’s sparrow: 90.8 percent loss

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
