California and Utah are losing more than a million wild birds each day due to habitat loss and invasive species, a new study shows.
The study, published Wednesday in the journal Science Advances, also found that the birds’ numbers are shrinking in some places, with California losing the most.
Researchers from the University of California-Davis used data from the U.S. Fish and Wildlife Service’s Audubon-USFWS Wildlife Loss Monitoring Program and the California Department of Fish and Game’s Audobon Conservation Monitoring Service to determine which states and territories were losing the greatest numbers of native birds.
They found California was losing the largest number of native bird species, at 8.2 million native birds, followed by Arizona with 8.1 million native bird deaths, Utah with 872,000, and Wyoming with 762,000.
Arizona and Utah were among the top 10 states for the total number of species lost annually, according to the study.
The number of bird species lost each year is determined by counting birds in habitat or living areas and counting all species that are threatened or endangered.
California and Utah have been the most affected states by invasive species.
California has the most native species lost to invasive species in any state, with more than 1.5 million native species.
Utah has the second-most, with 636,000 native birds in California.
In Arizona, California has more than 2.5 times the native bird populations of Utah, with 3.6 million native avian species, according the study, which is based on data from Audubons’ Audubosia bird-watching website.
The study was conducted by researchers at the University, Arizona State University and the University at Albany.
In Utah, the loss of native species is a problem for the state because of the large number of birds that live in Utah and the threat that some of those birds pose to habitat.
For instance, in southern Utah, some bird species are threatened with extinction, and some native bird communities are threatened by human development.
The loss of many bird species can have a major impact on their populations.
Some of the most significant species are California condors, which can breed only in the northern parts of the state.
Other species that breed in Utah include California ash, which breeds in the desert south of the Salt Lake Valley and in the southern part of the State.
California ash is one of the last remaining birds that can breed in the Utah desert, according that it was listed as endangered in 2003.
This means that the population of ash is limited and could be in danger.
The Utah bird population also includes the golden-crowned dove, which feeds on salt marsh and is threatened by development.
It breeds only in Arizona, the state with the largest population of golden-headed dove in the U
