While studying a ground-nesting bird population near El Reno, Okla., a research team found that stress during a severe weather outbreak of May 31, 2013, had manifested itself into malformations in the growing feathers of the young birds. The team witnessed a phenomenon termed ‘pallid bands’ in a large proportion of fledgling Grasshopper Sparrows and found spikes in the chemical signatures of ‘pallid bands,’ which led to abnormalities in the new feathers.
