| Cuckoos are widely distributed, but are concentrated in the tropics, where they occupy a wide range of habitats. Both terrestrial and arboreal behaviors can be found in this group, but there is no consensus on as to whether these behaviors have arisen more than once. Moreover, the historical distribution of cuckoos is poorly understood. This paper presents a biogeographyc analysis of the early history of the distribution of these birds. The analysis was performed by using the Principle of Parsimony based on primary and secondary "Brooks Parsimony Analysis" (BPA). Despite some exceptions, the primary BPA corroborated events of vicariance (general pattern) in the early distribution of cuckoos and a terrestrial ancestor widespread in the Gondwana. The most... |

| In its present state, the corpus of knowledge constituting our understanding of the Chrysococcyx 'malayanus' group is too unorganized to be used directly as the foundation for a modern systematic appraisal. A n attempt is here made to rectify this by overhauling the available facts. Stemming from this exercise, a few simple preliminary adjustments to the nomenclature and taxonomy of the group are suggested. The taxa here recognized are C. minutillus (with subspecies peninsularis subsp. nov., albifrons, cleis subsp. nov., minutillus and barnardi), C. russatus (subspecies aheneus, jungei, misoriensis and russatus), C. rufomerus, C. crassirostris and C. ruficollis. The type description of Cuculus malayanus Raffles, 1822 being recognizable as a femalephase... |
