Cerulean Warblers are
becoming a less and less common sight in the eastern United States, as habitat
loss and fragmentation is thought to be behind a steady decline in recent
decades. They are also fairly common hosts to Cowbird
parasitism. They have been found fairly regularly in Newton Hills State Park,
but there are no regular records of breeding there (SDOU).
Habitat: Found in
mature deciduous forests with a relatively open understory during the summer
breeding season, especially along rivers and streams. Winters in similar forest
habitats during the winter, often near forest edges and clearings.
not well-known, but thought to feed almost exclusively on insects.
Behavior: Usually forages high in the trees, rapidly flitting from branch
to branch in search of food items. Will also occasionally fly from perches
to catch flying insects.
Breeding: Non-breeder in South Dakota
Migration: Summers in
scattered portions of the eastern United States and extreme southeastern
Canada. Winters in South America.
South Dakota "Hotspot": A very rare visitor
anywhere in the state, but Newton Hills State Park in Lincoln County is
undoubtedly the best location to try and find these birds in South Dakota.
They have been found there fairly regularly during the summer months and may
be breeders there, although confirmed nesting records are few.
Conservation Status: Numbers are in decline in
recent decades, most likely due to habitat loss and habitat fragmentation,
both in its summer breeding grounds and on its wintering grounds.
