  • ABSTRACT. We show that the topology of separate elements in avian compound rhamphothecae are strongly similar among different clades, not only in external appearance but in how these elements conform to underlying structures. We conducted a morphological survey of 81 extant bird species and tested superficial similarities in external beak morphology for substantive similarity in associated skeletal structures and nerve courses. A revised set of morphological characters for compound… CONTINUE READING
