Banders Kristen Covino and Sara Morris co-authored a paper on 50 years of Black-throated Blue Warbler migration in North America, which was published in 2020 in The Auk: Ornithological Advances. The study showed that spring migration is occurring approximately one day earlier per decade, on average, while during the fall, the peak did not change but the migratory season is becoming more protracted.
