Priorities for Future Research

The White-tailed Iora is not a widely-studied species, and the following are the priorities for future research:

1) A population assessment of White-tailed Iora should be made in India and Sri Lanka to know about its current status and population trend. Surveys should be carried out in eastern India to know if it is still present there. Since it prefers thorn scrub jungles, the effect of changes in its habitat due to human activities should be studied in detail so as to understand its dependence on the habitat and changes in populations due to human activities. Special emphasis should be given to know the population in Sri Lanka and to understand whether it is vulnerable to human activities and whether this isolated population can be classified as needing protection.

2) Its reproductive biology is not well studied and the incubation period and fledgling period is not known. Whether pairs have a second brood is also not known. The reproductive success and the reasons for success or failure have not been studied. Breeding studies should be prioritized in order to establish the factors affecting breeding success or failure.

3) The life span, territoriality, and short distance movements in the non breeding season, if any, are not known. Future research should also focus on these aspects of its life history. This can be done by tagging a few individuals from different populations in northern and western India, southern India, and Sri Lanka.

4) Whether there are consistent vocal differences in songs and calls from Sri Lanka and southern India from birds in northern and western India requires further study. The notes/song, note length, song bandwidth, song delivery and length from northern and western India should be compared and statistically analyzed with those from southern India and Sri Lanka to find out the differences between them.

5) The Sri Lankan population needs special study as it exhibits morphological and vocal differences from populations in India. The White-tailed Iora in northern and western India, southern India, and Sri Lanka should be studied in detail morphologically and vocally, and samples for DNA analysis should be taken from these regions, to know if there are consistent differences in these three populations. There is potential for taxonomic revision, which can be confirmed after further studies.

6) The habitat preferences of the White-tailed Iora in its range should be studied so as to understand how much of its habitat lies in protected areas and how much is outside protected areas. Conservation strategies for habitats outside protected areas should be worked out.
