Oriental Cuckoo: 15 Facts You Won't Believe!

One of the interesting Oriental cuckoo facts is that it is secretive in its habits.

The oriental cuckoo is also known as Horsfields cuckoo. Its scientific name was often confused with Cuculus horsfieldi in the past, but its actual scientific name is Cuculus optatus. The range of this species is extremely large and the population trend seems to be stable. They are very quiet and secretive when not in the breeding season due to which it is very difficult to identify their wintering range. Their breeding range lives across northern Eurasia east to northern China, Korea, and Japan. Whereas, their non-breeding range includes Malaysia, Indonesia, the Philippines, New Guinea, and western Micronesia. They also migrate to northern and eastern Australia, Ukraine, Israel, Alaska, and New Zealand. The oriental cuckoo call is similar to that of the hoopoe. The male species are slightly low-pitched in comparison to the female species. It gets tough to spot the oriental cuckoos because they prefer to stay inside the tree foliage. They are brood parasites and lay their eggs in the nests of the Arctic warbler, willow warbler, chiffchaff, belonging to the Phylloscopus genus and the young cuckoos push out the eggs of the host species within a few days. They feed on insects and caterpillars are their favorite food. They look medium-large sized with grey upperparts, dark barring breasts, yellow decurved bill, orange-yellow feet, and a dark grey, long tail, and wings. The Pallid cuckoo, shining cuckoo, common cuckoo, lesser cuckoo, and the Himalayan cuckoo are all very similar to the oriental cuckoo in appearance. Oriental cuckoos easily get mobbed by the other birds.
