The distribution records with photographic evidence of the Beautiful Nuthatch Sitta formosa (Blyth, 1843) and Lesser Adjutant Leptoptilos javanicus (Horsfield, 1821) from the Tsirang District landscape in Bhutan. S. formosa, under Sittidae family, was first described in 1843 and is native to the eastern Himalaya, northeastern India, and extending into southeastern Asia. L. javanicus being widely distributed is rare and faces threats from deforestation, leading to its vulnerable status. The largest wading bird in the Ciconiidae family, found mainly in southern and southeastern Asia, with a recent sighting in Tsirang District establishing new distribution records for Bhutan.
