Winter Wren

Troglodytes hiemalis

Summary ⁴

The winter wren (Troglodytes hiemalis) is a very small North American bird and a member of the mainly New World wren family Troglodytidae. It was once lumped with Troglodytes pacificus of western North America and Troglodytes troglodytes of Eurasia under the name winter wren.

Taxon biology ⁵

This small perky little bird is one of the most common birds in the Netherlands. It may be small but it is extremely boisterous. In fact, you hear wrens more often than you see them. They are forest birds, but will make their nests anywhere where you find trees. Hundreds nest in gardens, parks, woods and even in the dunes nowadays. They eat small animals, such as spiders and insects. But when scarse, they easily switch to seeds and berries.

Conservation status ⁶

With 36,000,000 individuals and no serious trends of declining populations, winter wrens are not considered a species of concern. Populations of winter wrens in Britain are increasing.

US Migratory Bird Act: protected

US Federal List: no special status

CITES: no special status

State of Michigan List: no special status

IUCN Red List of Threatened Species: least concern

Habitat ⁷

Winter wrens are found in a wide range of habitats. They prefer deciduous forests, but they are also common in pastures, farms, scrub forests, coniferous forests, towns, and villages. They also occur on heath, grasslands, marshes, and in croplands. Winter wrens prefer thick vegetation close to the ground.

Justification

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). The population trend appears to be increasing, and hence the species does not 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.
