Hoopoe

The Hoopoe is a medium sized bird, 25–32 cm (9.8–12.6 in) long, with a 44–48 cm (17.3–19 in) wingspan weighing 46–89 g (1.6–3.1 oz). The species is highly distinctive, with a long, thin tapering bill that is black with a fawn base. The strengthened musculature of the head allows the bill to be opened when probing inside the soil. The hoopoe has broad and rounded wings capable of strong flight; these are larger in the northern migratory subspecies. The Hoopoe has a characteristic undulating flight, which is like that of a giant butterfly, caused by the wings half closing at the end of each beat or short sequence of beats.
The call is typically a trisyllabic oop-oop-oop, which gives rise to its English and scientific names, although two and four syllables are also common. In the Himalayas, the calls can be confused with that of the Himalayan Cuckoo (Cuculus saturatus) although the cuckoo typically produces four notes. Other calls include rasping croaks, when alarmed, and hisses. A wheezy note is produced by females during courtship feeding by the male. Both genders shout by disturbance rough charrrrrr what strongly reminds of the warning cry of the Eurasian Jay. The feed begging of the nestlings is a similar to Common Swift tiiii
