1 For extraction of the Thamnophilidae from this family see Sibley & Monroe (1990) [Sibley, 1990 #3636], Harshman (1994) [Harshman, 1994 #4385], Chesser (2004) [Chesser, 2004 #744] and Moyle et al. (2009) [Moyle, 2009 #11813].
2 For extraction of the Grallariidae from this family, see Irestedt et al. (2002) [Irestedt, 2002 #2073], Chesser (2004) [Chesser, 2004 #744], Rice (2005a,b) [Rice, 2005 #10048], [Rice, 2005 #10049] and Moyle et al. (2009) [Moyle, 2009 #11813].
3 For treatment as a separate species from F. analis, see Howell (1994) [Howell, 1994 #2017] and Krabbe & Schulenberg (2003) [Krabbe, 2003 #4400].
4 Accidentally named in Furnarius but immediately emended, apparently in the same volume.
5 Subspecies groups follow Sibley & Monroe (1990) [Sibley, 1990 #3636].
6 May comprise more than one taxon; see Krabbe & Schulenberg (2003) [Krabbe, 2003 #4400].
7 Includes olivaceus; see Krabbe & Schulenberg (2003) [Krabbe, 2003 #4400].
8 May consist of as many as four species; see Krabbe & Schulenberg (2003) [Krabbe, 2003 #4400].
9 Considered by Sibley & Monroe (1993) [Sibley, 1993 #9208] to form a superspecies with C. nobilis and C. meruloides.
10 The stem colomb- used in Dickinson (2003) [Dickinson, 2003 #9533] was incorrect.
11 Perhaps not diagnosable from nominate campanisona; see Krabbe & Schulenberg (2003) [Krabbe, 2003 #4400].
12 May merit treatment as a separate species; see Krabbe & Schulenberg (2003) [Krabbe, 2003 #4400].
13 For treatment as a separate species see Willis (1992) [Willis, 1992 #4225].
14 For treatment as a separate species from C. ruficauda, see Willis (1992) [Willis, 1992 #4225] and Ridgely & Tudor (1994) [Ridgely, 1994 #3272].
15 Historically treated as conspecific with the next species, but see Willis (1992) [Willis, 1992 #4225] and Ridgely & Tudor (1994) [Ridgely, 1994 #3272].
