| | MONOPHYLY OF THE FALCONIFORMES BASED ON SYRINGEAL MORPHOLOGY |
 | | I analyzed 124 falconiform syringes and 66 syringes from purported outgroups (Appendix 1). |
 | | Because monophyly of the Falconiformes could not be as- sumed, species from these other orders were not treat- ed as outgroups in the analysis, nor was there a con- straint on monophyly imposed in the analysis (Maddison et al. |
 | | Falconiformes cur- rently consists of 76 genera and 290 species di- vided into four families (Stresemann and Area- don 1979): Accipitridae, including Accipitrinae (hawks and eagles, 59 genera, 217 species) and Pandioninae (Osprey, monotypic); Falconidae (falcons, 10 genera, 62 species); Cathartidae (New World vultures, 5 genera, 7 species); and Sagittariidae (Secretarybird, monotypic). |
