Large cuckooshrike

A male from West Bengal

Adult males have a broad and well-marked eye stripe which is pale in females. The throat and breast are grey in males and the abdomen and flanks are finely barred. Females have the throat and breast also with barring which extends further down and lacks the prominent whitish vent of the male. They are mostly insectivorous but also feed on figs and forest fruits and usually fly in small groups with a bounding flight just above the forest canopy. The Indian population has a loud call klu-eep and the birds have a characteristic habit of flicking their closed wings one after the other upon landing on a perch. The same wing movements are also used during courtship.[2]

Several subspecies are recognized but there is considerable confusion and the taxonomy of the group is not fully resolved.[4] The IOC classification considers the following subspecies within the species macei:

• C. m. nipalensis (Hodgson, 1836) of the Himalayas (some authors treat this as a subspecies of C. javensis)
• C. m. macei (Lesson, R, 1831) of peninsular India
• C. m. layardi (Blyth, 1866) of Sri Lanka
• C. m. andamana (Neumann, 1915) of the Andaman Islands
• C. m. rexpineti (Swinhoe, 1863) of southeastern China, Taiwan, Laos and Vietnam
• C. m. larvivora (Hartert, 1910) of Hainan (off China)
• C. m. siamensis (Baker, ECS, 1918) of Myanmar and southern China to southern Indochina
• C. m. larutensis (Sharpe, 1887) of the Malay Peninsula (some authors treat this as a subspecies of C. javensis or as a separate species)

The species was for sometime lumped, treated as a subspecies of Coracina novaehollandiae within the caledonica superspecies.[5]

The species breeds in the dry months of winter. The nest is a shallow saucer placed in the fork of a horizontal branch at some height above the ground. The saucer is made of twigs and grass decorated on the outside with cobwebs and with little lining. The typical clutch is three eggs in peninsular India and two around Bengal.[2]
