Buildings are one of the top bird killers in the United States, with more than a billion birds dying after a building crash each year. About 60% of birds brought to wildlife rehabilitators or emergency rooms for animals die while in care of the facility either by succumbing to their injuries or euthanasia, according to a new study released in the Public Library of Science Journal on Wednesday.
There has been a widespread bird population decline in North America over the past half-century. The North American bird population is down by nearly 3 billion birds since 1970 according to a Cornell Lab study, making addressing hazards to bird ecosystems more urgent.
The injured birds are often brought to wildlife rehabilitation centers with head trauma and concussions. The bigger the bird, the more likely it was that it would recover and be released back into the wild. The rehabilitation centers examined in the study found that they received the greatest number of bird patients in the fall with the least number of admissions in the winter.

Washington — The Supreme Court on Thursday cleared the way for the Trump administration to deport a group of migrants with criminal records held at a U.S. naval base in Djibouti, clarifying the scope of its earlier order that lifted restrictions on removals to countries that are not deportees' places of origin.
