Abstract

Indian robin (Copshychus fulicatus L.) prefer fragmented, degraded, mixed forest patches with scattered settlements in semi-urban areas. Breeding season initiated by the first fortnight of March with the onset of singing by territorial males. Breeding behaviour of total 54 individuals was observed during March 2021 to August 2023 with post-breeding dispersal behaviour in Himalayan foothills, valley area of Dehradun, India. Nest building period was observed 11.31± 1.08 days, both sexes participated in nest formation and parental caring. Nests were made up of thin twigs with fine inner lining, having a shallow cup shaped structure. Four type of nest were observed based on the morphological parameters labelled as: Type-I, Type-2, Type-3, and Type-4. Significant differences were observed among the nest types for all measured parameters, as indicated by highly significant p-values (p ≤ 0.001). Clutch size and number of brood were 3.34 ± 0.14 eggs and 2-4 respectively. Incubation was performed by only female individuals, while males were seen guarding the nest during incubation phase. Average incubation period was about 11.99 ± 0.26 days with hatching success 81 % and the young ones fledged in 13.09 ± 0.30 days.

Conclusion

This study provides valuable insights into the nesting behaviour, nest characteristics, and breeding phases of Indian Robin in Northern India. The results highlight the need for conservation actions to address the declining hatching success and preserve suitable nesting habitats. By understanding the reproductive biology of Indian Robin, we can contribute to their long-term survival and contribute to the broader field of avian ecology and conservation. The examination of nest characteristics provided valuable insights into the nesting behaviour and adaptations of Indian Robin in the selected area of Northern India. In generally birds of a species make almost same type of nests however some anomalies could be observed.
