Which specific forest types does the Oriental Dwarf Kingfisher favor besides primary and secondary forests?

Alluvial forests, mangroves, and overgrown plantations or palm/bamboo thickets

The Oriental Dwarf Kingfisher demonstrates a specialized habitat requirement centered around dense cover and shade, typically found in lowland settings. While it shows a preference for primary and secondary deciduous and evergreen forests, it is adaptable enough to utilize several other dense formations. These suitable alternative environments include alluvial forests, which are nutrient-rich areas often near rivers; mangrove ecosystems, showcasing its tolerance for brackish areas; and even heavily overgrown areas such as plantations or dense thickets composed of palm or bamboo species. The crucial factor appears to be maintaining the density of the overhead canopy.
