== Conservation ==
Though the current conservation status of Red avadavat is Least Concern (LC), it has become increasingly uncommon in at least part of Southeast Asia. In Thailand, they are described an uncommon to rare resident.<ref>Round, Philip & Gardner, Dana. (2008). Birds of the Bangkok Area. </ref> In Cambodia, Red avadavats were already "exported by the thousands" to Vietnam in the 1920s, described as "uncommon and irregular" in the early 1960s, and populations are now considered to be low and of concern, yet significant numbers were still found in the [[Life release|merit release]] trade in 2012.<ref>{{Cite journal |last1=Gilbert |first1=Martin |last2=Sokha |first2=Chea |last3=Joyner |first3=Priscilla H. |last4=Thomson |first4=Robert L. |last5=Poole |first5=Colin |date=September 2012 |title=Characterizing the trade of wild birds for merit release in Phnom Penh, Cambodia and associated risks to health and ecology |url=https://linkinghub.elsevier.com/retrieve/pii/S0006320712002066 |journal=Biological Conservation |language=en |volume=153 |pages=10–16 |doi=10.1016/j.biocon.2012.04.024|bibcode=2012BCons.153...10G |url-access=subscription }}</ref>
