Migratory Bird of the Day: Yellow-billed Cuckoo
Hold onto your binoculars and get ready for the charming Yellow-billed Cuckoo! With its sleek brown body, white underparts, long black tail spotted white underneath, and striking down-curved yellow bill, this bird stands out in the crowd. This stealthy bird can be difficult to spot, however, as it often sits motionless for long periods of time. When disturbed, it holds its body low and moves quietly along branches, disappearing quickly into the foliage. In flight, its reddish-brown wing patches are diagnostic.
The Yellow-billed Cuckoo is quite the traveler! They breed in the eastern two/thirds of North America as well as in the Bahamas, Greater Antilles, and parts of Mexico and Central America. They winter almost entirely in South America, east of the Andes and can be seen in many Caribbean countries on migration, sometimes passing through in huge numbers.
They are caterpillar connoisseurs, chowing down on these wriggly treats like true bug busters. Their soft, hollow “cu-coo cu-coo cu-coo” calls might make you feel like you’re in the heart of the wilderness. It’s like a calming lullaby echoing through the trees. But they also have a distinct, louder and more guttural “ka-ka-ka-ka-ka-kow-kow-kowlp-kowlp-kowlp-kowlp” call. In North America it has earned the nickname ‘rain crow’ or ‘storm crow’ because it calls just before the rain and sometimes continues to call throughout the rainfall.
When love is in the air these cuckoos pair up and get straight down to business. The breeding cycle from egg laying to fledging takes only 17 days! Pairs construct flimsy nests in dense shrubs and the female usually lays 2-3 eggs.
Yellow-billed Cuckoos are well-known for their “parasitic” behavior—they sometimes lay additional eggs in other birds’ nests, both their own species and others, such as American Robin, Wood Thrush, Gray Catbird, and Red-winged Blackbird. This remarkable behavior, that is, “parasitizing” the parental care of other birds, is an adaptation for increasing their own reproductive success. Because it grows so quickly, a cuckoo chick is able to outcompete its nest mates for food. Cuckoo chicks beg vigorously and have even been observed standing on the backs of their nest mates to monopolize the parent’s feeding!
Now, let’s talk about serious stuff. The elusive Yellow-billed Cuckoo faces challenges just like other birds. Habitat loss from development is a major threat, especially on its wintering grounds. Climate change, invasive species, and pesticides (which kill and contaminate their insect prey) are also serious threats. So, what can you do? Support conservation efforts—donate to organizations that protect nature, get involved in citizen science projects, and spread the word about these incredible birds.
Together we can make sure the Yellow-billed Cuckoo continues to grace our skies for generations to come! Learn more about this species, including its range, photos, and calls here.

Activity of the Day
FOR KIDS: Today’s bird, the Yellow-billed Cuckoo, loves to include insects in its meals! Why not explore outside and “meet the insects” in today’s activity! You will get up close to some of those mini-beasts that are crawling, flying and even munching on leaves in your own backyard. You can download all the instructions for this activity here, including instructions for how to make your own ‘mirror box’ for looking at the insects!
For this activity you’ll need:
- an old light colored bed sheet or towel will work
- a magnifying glass or mirror box (see page 3)
- garden gloves (optional)
- camera
- sheet of paper and pencil
Note: You will need a parent or trusted adult to help you with this activity!
FOR KIDS AND ADULTS: Enjoy this video of a Yellow-billed Cuckoo in the wild!
