Much noteworthy avian information has accrued since the publication of The Birds of Gambell and St. Lawrence Island, Alaska (Lehman 2019). These include first-time records as well as many new early arrival and late departure dates, high counts, and additional records of rare and casual species. From 2019 to 2025, 14 new species were recorded on St. Lawrence Island. Two, Pallas’s Grasshopper Warbler (Helopsaltes certhiola) and the Icterine Warbler (Hippolais icterina), were also firsts for North America. Another two species were new at the village of Gambell but had previously been recorded elsewhere on the island. In addition, the taxonomic splits of the Vega Gull (Larus vegae) and American Herring Gull (L. smithsonianus) from the Herring Gull (L. argentatus) and of the Siberian Pipit (Anthus japonicus) from the American Pipit (A. rubescens) were accompanied by the merging of Common Redpoll (Acanthis flammea) and Hoary Redpoll (A. hornemanni) into a single species. These discoveries and reclassifications bring the species total at Gambell to 303 and on St. Lawrence Island to 307.
