Hobson, Elizabeth, Michael Avery, Timothy Wright. The socioecology of Monk Parakeets: insights into parrot social complexity. The Auk: Ornithological Advances 131(4): 756-775.
**Note: Due to a bug in SOCPROG 2.4, the reported dominance hierarchy steepness values we reported were inaccurate. Steepness for both captive groups is more moderate than previously reported (~0.5 rather than <0.1), now placing the two groups midway on the egalitarianism/despotism continuum. This change in steepness does not alter our general findings about Monk Parakeet socioecology. An erratum is now available.
