Cuculidae Family - Old World Cuckoos
The cuckoo family Cuculidae contains six subfamilies. The first three listed below are found in the New world, while the remaining three are found in the Old World.
*
Coccyzinae – New World Cuckoos
* Neomorphinae – New World Ground Cuckoos
* Crotophaginae – Anis
* Cuculinae – Old World Cuckoos
*
Phaenicophaeinae – Malkohas and Couas
*
Centropodinae – Coucals
This article is about the
Cuculinae subfamily which contains
brood parasitic Old World cuckoos. The are arborel cuckoos, spending much of ther time in trees looking for insects, especially caterpillars. There are 8 genera that contain more than one sprcies. These are discribed briefly below.
* Cacomantis: 9 species. They have mainly brown and grey plumage. Their tails are graduated and barred. Many have caterpillars on their list of favorite foods and they thus tend to be arboreal.
* Cercococcyx: 3 species. They all have "long-tailed" as part of their name. They are found in Africa. They are secretive and not often photographed. Their habitat are forests and thickets where they are mainly arborieal in trees but also in thckets.
* Chrysococcyx: 11 species. Many of the bronze-cuckoos have bronze-like coloring on some of their upperparts. For many of the species the males and females have different plumage. They are all parasitic, laying their eggs in the nests of other species. Most live arboreally in forests where they feed on caterpillars and other insects. They are found in Africa, Asia, and Australasia.
*
Clamator: 4 species These are brood parasites, which lay a single egg in the nests of medium sized hosts, such as magpies, starlings, shrikes, laughingthrushes, bulbuls and babblers, depending on location. Clamator cuckoos are found in warmer parts of southern Europe and Asia, and in Africa south of the Sahara Desert. These are birds of warm open scrubby habitats. Some species are partially migratory, leaving for warmer and wetter areas in winter.These are large cuckoos, with broad chestnut wings and long narrow tails. They are strikingly patterned with black, white and brown plumage. The sexes are similar.
*
Cuculus: 10 species. These are vocal species, with persistent and loud calls. They feed on large insects, especialy hairy caterpillars, which are distasteful to many birds. They prefer open woodland instead of thick forest. Most have grey upperparts, partially-barred pale underparts. Many have yellow feet and eye-rings.
* Eudynamys: 2 or 3 species. These koel cuckoos are found in Asia, Australia, and the Pacific. The males have mainly black plumage while females have dark brown upperparts with light freckles and heavily striped whitish underparts. The bills are pale grey-green, except for the black-billed koel, a subspecies of the Asian Koel. They are brood parasitic.
* Hierococcyx: 8 species. The hawk-cuckoos resemble hawks, not only in apperance but also some of their behavior such as how they fly and land on a perch They have yellow eye-rings and yellow feet.
* Surniculus 4 species. The drongo-cckoos have mainly black plumage. They resemble drongos which have the same general shape and also have black plumage. Whether or not there is an advantage to this resemblance is unknown. It could be a coincidence.
The cuckoo family Cuculidae
The cuckoo family Cuculidae is the only family of the order Cuculiformes. The family is represented on all continents except Antarctica. Most species reside in tropical or subtropical environments. Those in temperate locations migrate to avoid cool or cold winters. In addition to cuckoos, the family Cuculidae also includes the roadrunners, koels, malkohas, couas, coucals and anis. The coucals and anis are sometimes separated as distinct families. The
cuckoos are generally medium sized slender birds. The majority are of the cuculidae family are arboreal, with a sizeable minority that is terrestrial.
Cuckoos are medium sized birds that range in size from 15-63 cm. There is generally little sexual dimorphism in size, but where it exists, it can be either
the male or the female that is larger, depending on the genera. There are two basic body forms, arboreal species which are slender and terrestrial species which are more heavy set and have stronger legs. Almost
all species have long tails which are used for steering in terrestrial species and as a rudder during flight in the arboreal species.
Many species are brood parasites, laying their eggs in the nests of other species, but
the majority of species raise their own young. The brood parasitic birds usually only parasitize a single host species or a small group of closely related host species. They tend to remove a host egg when they lay one of their own in a nest. This both prevents the host species from realizing their nest has been parasitized and reduces food competition for the parasitic nestling once it hatches. Some brood parasites will eliminate all their nest-mates shortly after hatching. If the host removes a parasitic egg or chick, the adult parasitic birds may retaliate by destroying the nest.
There has been an evolutionary arms race between the cuckoos that leave their eggs in other nests, and the hosts that get these unwanted presents. The cuckoos have evolved to be able to lay their eggs faster than most other species and the eggs need less incubation time before hatching. These eggs often resemble the host eggs to prevent detection of an invader egg. The drongo-cuckoos resemble their host. Some hosts have evolve to be social so the colony can be on the lookout for an invader trying to deposit an egg. Others have more than one brood of chicks per year so there will be replacements for any losses due to cuckoos.
Cuckoos feed on insects, small animals, seeds, and fruit. For many cuckoo species, caterpillars are their favorite food; even hairy caterpillars that are avoided by most other birds. Cuckoos can consume hairy caterpillars because of their ability to shed their abdominal lining and get rid of the hairs via a pellet. Another favorite food of many cuckoos are grasshoppers. We may find it repugnant that some cuckooos are brood parasitic and they or their offspring even kill the host's chicks, but on the plus side cuckoos help prevent plagues of caterpillars and grasshoppers!
Almost all cuckoos are shy which can make them a challenge to observe and photograph. Consistent with this behavior, they are not colonial breeders. These traits may be have their roots in their brood parasitic behavior. Stealth is a good characteristic if you want to sneak an egg into a host's nest.
Cuckoo family members are zygodactyl: they have the 2 inner toes facing forward and 2 two outer toes facing to the rear.
Old World Cuckoos
Genus Cacomantis
The genus name is derived from the Greek kakos meaning evil or ill-boding and mantis for prophet and is derived from their association with "rains" being supposed to be predict ill fortune and bad weather. The cuckoos of this genus have mainly brown and grey plumage. Their tails are graduated and barred. Many have caterpillars on their list of favorite foods and they thus tend to be arboreal.

Genus Cuculus
These Old World cuckoos lay a single egg in the host's nest. The cuckoo chick hatches earlier and grows faster than the host's chicks. It usually evicts the host's eggs or chicks from the nest. These are vocal species, with persistent and loud calls. They feed on large insects, especialy hairy caterpillars, which are distasteful to many birds. They prefer open woodland instead of thick forest. Most have grey upperparts, partially-barred pale underparts. Many have yellow feet and eye-rings.
