Common Iora

<em>Aegithina tiphia</em>, commonly known as the common iora, is a small passerine bird in the family Aegithinidae. It is classified as Least Concern on the IUCN Red List. The species is recorded in Norway and occupies a variety of aerial, terrestrial, and aquatic environmental zones, reflecting its use of diverse habitats including gardens, forests, mangroves, and scrubland across South and Southeast Asia.
