The New World species has distinctive black, down curved bill and red circle around the eyes. The brown upperparts and white underparts also become the characteristic of this bird.

Birders can find the black-billed cuckoo in several habitats such as the edges of mature forests and young forests. Wetlands and open areas such as farmlands and golf courses are also good location to see cuckoos. And yet, they are typically shy and like to hide.

The cuckoos forage in the thickets and shrubs to hunt insects. They also feed on berries, eggs of other birds, and snails. During the breeding season, the black-billed cuckoo can be easily found throughout the United States especially in the east of Rocky Mountains.

Also known as rain crow in the southern US, the bird is identified by its yellow mandible, brown upper plumages and white underparts.

These birds rarely mingle with Lapland longspur, the more common species of longspurs or other birds in Illinois. Though you might find them in the same fields, they won’t be in the same flock. If you want to birdwatch the smith’s longspur, make sure it’s in April.
