Oriental Pied Hornbills Surprise Delhi with Unexpected Arrival
20 Mar
Summary
- Oriental pied hornbills, typically found in the Himalayas and northeast, are increasingly seen in Delhi.
- Birders suggest these hornbills may be escapees from the pet trade or accidentally arrived.
- Delhi's fruit-bearing trees and urban greenery provide a suitable habitat and food source.
Birdwatchers across Delhi-NCR have been increasingly observing the Oriental pied hornbill, a species not usually found in this urban expanse. These birds, more commonly associated with the lower Himalayas and northeastern parts of India, are now being sighted in south Delhi areas like Hauz Khas, Sukhdev Vihar, and the Aravalli Biodiversity Park. This trend suggests a significant shift from their traditional habitats.
Experts hypothesize several reasons for this unexpected presence. Some believe these hornbills may have arrived accidentally but have adapted well to the urban setting. Another prominent theory suggests that some of these birds could be escapees from illegal pet trade or private aviaries, a concern highlighted by the National Zoological Park acquiring a pair in September 2024. Despite their non-native status, the birds are thriving.
The adaptability of the Oriental pied hornbill is attributed to Delhi's rich urban greenery. The abundance of fruit-bearing trees, such as ficus, pilkhan, peepal, and banyan, offers a high-calorie diet essential for their survival. These trees, prevalent in the heavily wooded gardens of south Delhi, provide a consistent food source, allowing the hornbills to establish a presence in the city. Occasional sightings of single birds or pairs continue to be reported.
