Based on the phonological phase data of Indian cuckoo and meteorological data from 1983 to 2008 in Heze, the responses of the phonological phases of Indian cuckoos to climate changes are analyzed. The results show that the relationship between first warble dates and mean temperature from January to May was negative, and that of last warble dates with mean temperature from June to July was positive; the number of days from first to last warble and mean temperature were positively and significantly correlated. With increasing temperature, the first warble dates advanced by 3 days per 10 years, and the last warble dates delayed by 6 days per 10 years. The more sunshine days in early spring were beneficial to the advancement of the first warble dates, and the more sunshine days in autumn were beneficial to the delay of the last warble dates. The larger precipitation in spring and winter corresponded to the less number of days between first and last warbles.
