In my column on the State of the Birds 2022 (Dec. 29, 2022), I talked about how ornithologists evaluate the conservation needs of various bird species. The species accompanying today’s column were all used, among other species, by State of the Birds to calculate population trends by habitat — long-billed curlew, ferruginous hawk, and vesper sparrow, for grasslands; sage thrasher and sagebrush sparrow for aridlands.

U.S. air travel has returned mostly to normal, a day after a computer system that sends safety information to pilots broke down and grounded traffic from coast to coast. By early afternoon Thursday on the East Coast, only about 100 flights had been canceled and 1,700 delayed. Those figures are much lower than on Wednesday, when more than 1,300 flights were scrubbed and 11,000 delayed. The Federal Aviation Administration said a damaged database file appeared to have caused the outage in the safety-alert system. Transportation Secretary Pete Buttigieg promised a thorough examination to avoid another major failure.
