Figure 1. The Bay-winged Cowbird is "... locally common in semiopen areas, agricultural terrain and light woodland." (Ridgely and Tudor 2009, p. 668). In Ceará, it can for example be found in the municipalities of Tejuçuoca, Irauçuba, Tauá, and certainly many others. However, it is absent from apparently suitable semiopen agricultural areas in the vicinity of Mãe-da-lua reserve, and from Fazenda Canaã.
