Description
Peek-a-boo! The lesser cuckoo is an expert at hide-and-seek, often sneaking its eggs into the nests of unsuspecting other bird species. This master of disguise then leaves its offspring to be raised by foster parents, freeing up time to belt out its distinctive, rhythmic song. Did you know that its migratory journey covers a whopping 5,000 miles, spanning from the Indian subcontinent all the way to East Asia? Now that's a jet-setting bird!
The lesser cuckoo can weigh between 50to82grams and be from27to30centimeters tall.
The typical lifespan of the Lesser Cuckoo (Cuculus poliocephalus) is around 5 to 10 years. This lifespan is comparable to other cuckoo species, such as the Common Cuckoo, which can live up to 12 years. Lesser Cuckoos, like other cuckoos, engage in brood parasitism, laying their eggs in the nests of other birds. This strategy may enhance their survival by reducing parental investment. Despite environmental pressures, their adaptability helps maintain a relatively stable lifespan compared to other bird families.

Its eyes are a distinctive dark color, contrasting the soft tonal gradients of its plumage.
Male vs female
In Lesser Cuckoos, males and females appear quite similar, making sex differentiation challenging without close observation. Both genders display similar coloring, but males may exhibit slightly more vivid coloration on the wings and tail, particularly during mating season. However, these differences are subtle, often requiring an experienced observer to distinguish them accurately.
Juvenile
Juvenile Lesser Cuckoos differ from adults mainly in their overall muted coloration and less distinct barring on their underparts. Young birds exhibit a more uniform brown plumage, lacking the reddish tinge seen in adults. Their tail bands are less defined, and they may have a slightly scruffy appearance. These characteristics become more pronounced as they transition to adult plumage over their first year.
Breeding and nesting habits of the lesser cuckoo
Mating Behaviors
The Lesser Cuckoo engages in intricate courtship displays characterized by the male's song, a melodious "koo-kooo," to captivate the female's attention. Males are often seen pursuing females through the air in a dynamic chase, showcasing aerial agility. Socially, these birds are often solitary except during the breeding season, when males become territorial to attract partners. Breeding patterns suggest a preference for warm, humid conditions typically coinciding with their migratory patterns.
Nesting Details
Unlike many other birds, the Lesser Cuckoo doesn't build its own nest. It is a brood parasite, laying eggs in the nests of other bird species, such as warblers and babblers. Ideal nesting sites include gardens and forested areas where host birds build nests. For gardeners aiming to attract host species that may inadvertently support Lesser Cuckoos, dense shrubs and small trees provide shelter and nesting spots that appeal to potential host birds.
Eggs and Chick-Rearing
The Lesser Cuckoo typically lays one egg per host nest, relying on the unsuspecting host birds to incubate and rear the chick. The incubation period lasts about 11-13 days. Upon hatching, the cuckoo chick may instinctively push out other eggs or chicks to monopolize parental care. Dependent entirely on host parents, the cuckoo chick typically fledges within 15-19 days. This symbiotic relationship often influences the breeding success of both the cuckoo and the host species.
What does a lesser cuckoo like to eat?
Natural diet
The Lesser Cuckoo predominantly thrives on a protein-rich diet, mainly consisting of various insects and their larvae. This includes grasshoppers, beetles, caterpillars, and other small invertebrates, which it skillfully captures from foliage. During different seasons, the availability of these prey items changes, with a noticeable abundance in the spring and summer months when insects are more active. Besides, the bird occasionally supplements its diet with small fruits and berries when these insects become scarce, ensuring a balanced nutritional intake throughout the year.
Bird feeders
Although the Lesser Cuckoo is not a regular visitor to bird feeders, it might occasionally be enticed by specific offerings. Live mealworms, being a close substitute to its natural insect diet, are likely to attract this bird. Additionally, suet, which is high in fat, serves as an excellent source of energy, especially during migration. While seeds and typical bird seed mixes are usually not part of their diet, providing crushed nuts or dried fruits may offer alternative attractions. It's essential to ensure that feeder food offerings mimic the natural dietary preferences of the bird without relying too heavily on processed substitutes.
Choose the right feeder: tray feeders for lesser cuckoo
Lesser Cuckoos are known for their fondness for large, open areas when foraging. Opt for a tray feeder that offers enough space for them to comfortably perch and feed. This type of feeder allows them easy access to food, mimicking their natural feeding style. Make sure it is sturdy enough to support several birds at once, as these birds may travel in small groups.
Provide a menu of lesser cuckoo's favorite foods
These cuckoos prefer insects and larvae as their primary diet. Offer mealworms, caterpillars, and Bird Buddy seeds, which come packed with essential nutrients and are a consistent favorite among visiting Lesser Cuckoos. Combine these offerings with a mix of dried fruits and nuts to attract a wider variety and provide a balanced diet.
Optimal feeder placement to attract lesser cuckoo
Place your feeder in a quiet and undisturbed part of your backyard, preferably 4 to 6 feet above the ground. Lesser Cuckoos prefer areas with a good canopy overhead, as this provides them with a sense of security from predators. Ensure it's easily visible from a distance so that it catches the eye of these shy visitors as they pass by.
Seasonal considerations for attracting lesser cuckoo
Lesser Cuckoos are migratory birds, visiting gardens primarily in the spring and summer months. During these times, increase offerings, especially high-energy foods like Bird Buddy seeds and mealworms, to replenish their energy reserves during migration. In the fall, monitor feeder use as they prepare to leave and adjust offerings suitably.
Create an inviting habitat with water features and plants
Enhance your garden by adding a birdbath or a small, shallow water feature. This allows Lesser Cuckoos to drink and bathe. Integrate native shrubs and trees known to attract caterpillars and other insects. This ensures a natural food supply and offers them cover and nesting spots, creating a welcoming environment that can keep them coming back.
