The Bird's Nest Drawing (Kaiser, 1996) is an art-based assessment that was developed to assess attachment security. In the past 10 years, several studies have further tested this art therapy directive with various populations. This paper briefly reviews attachment theory, delineates the significant findings from five of the studies, and provides information from four others. Implications for clinical use of the Bird's Nest Drawing and need for future research are discussed. (Contains 4 figures and 1 table.)
