The Chestnut-sided Warbler breed in North America from the Great Lakes and southern Canada to the east coast. In winter they fly down to Central and South America as far south as Colombia.
In summer the male Chestnut-sided Warbler are strikingly colored. They have a dark gray back, white face, black eyestripes and chestnut flanks. They also have two light wing bars.
The Chestnut-sided Warbler is listed as Least Concern on the IUCN Red List and was last assessed in 2012 by BirdLife International. This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
