Little Heron Index Showed Clear Long-term Decline, While Recent Trend Remained Unclear

The 2025 interim update from State of India’s Birds reported revised national numerical estimates for the Indian population now treated as little heron (Butorides atricapilla). The numerical update was released on 6 May 2026. The source page still uses the former name Striated Heron (Butorides striata) because the assessment predates the recent taxonomic split.

The long-term numerical trend was estimated at −37.9% and clearly supported a long-term decline. The current annual estimate was −0.53% per year, but its uncertainty was too broad to establish a clear recent increase or decline. The species page still displays the carried-over 2023 categories Decline for the long-term trend and Trend Inconclusive for the current annual trend; these labels were not recalculated from the 2025 numerical estimates.

The updated model estimated an Indian distribution range of 1,187,727 km². State of India’s Birds describes the population as resident, wetland-specialised and non-endemic to India, and retains it in the Moderate conservation-priority category.

The 2025 numerical trends describe change in a reporting-based abundance index rather than direct counts of individual birds.

A global Butorides phylogeny published in March 2026 supported treating the Old World populations formerly included in the broad B. striata complex as little heron B. atricapilla. The Indian State of India’s Birds figures therefore refer to the Old World population now treated as Little Heron, even though the source page retains the older scientific and English names.
