One thought on “Schrenck’s Bittern (Ixobrychus eurhythmus)”
A population decline in its breeding grounds in the Amur region, Russia Far East, is very likely, as the frequency of fires has increased, leaving few patches of suitable reedbeds for the species. In this study, Schrenck´s Bittern was only detected in a transect not affected by fire in the same year (but sample size not significant): https://link.springer.com/article/10.1007/s10531-019-01746-3

At Muraviovka Park, the population was estimated at 20-30 calling males in 2013 (see https://static1.squarespace.com/static/5c1a9e03f407b482a158da87/t/602538a595b66d0de64514ee/1613052077725/Muraviovka-Park.pdf). Populations of similar sizes are likely found in other nature reserves along the Amur river and its tributaries, so the population in the Amur region likely numbers 100s-1000s of individuals. Information on densities in the Amur region are summarized in the Red Data Book of the Amur region: https://redbook28.ru/zhivotnye/pticy/amurskij-volchok/
