Wrens in California: sources
Every number on this page comes from the EOD – eBird Observation Dataset published by the Cornell Lab of Ornithology and distributed through GBIF under a CC BY 4.0 license: California records from 2020–2024, retrieved 2026-09-18. Species are drawn from the families Troglodytidae; only species with at least 25 records are listed, and a species is called a year-round resident when its monthly share of state records stays above 30% of its own peak in ten or more months. “Records” are individual eBird observations, so they reflect how often birders report a species, not a population count.
