A grove in Veḷuvana at Rājagaha. It contained a Paribbājakārāma, the resort of recluses of various denominations. The Udumbarikā Sutta, the Mahāsakuludāyi Sutta, and the Cūḷasakuludāyi Sutta were taught there (D.iii.36 ﬀ; M.ii.1, 29).
The place was so called because peacocks were protected there and food was provided for them (DA.iii.835; MA.ii.694).
The Moranivāpa was on the bank of the Sumāgadhā and the Buddha is mentioned (D.iii.39) as walking there. Not far away was the park of the Queen Udumbarikā (D.iii.36).
