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: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
