| Individual, sex, age, seasonal and geographic variation of size and plumage coloration of Lesser Whitethroat Sylvia curruca (Linnaeus, 1758) was studied on more than 1100 bird skins from all parts of its breeding range. The results of analysis of birds from the south-eastern part of the breeding range of the species support the validity of five light-coloured subspecies: halimodendri Sushkin, 1904, telengitica Sushkin, 1925, snigirewskii Stachanow, 1929, minula Hume, 1873, and margelanica Stolzmann, 1897. Their diagnoses and ranges are refined and supplemented. Numerous phenotypically intermediate birds from intergradation zones between the subspecies show that these five together with the two northern darkcoloured forms S. c. curruca and S. c. blythi... |

| The taxonomy of the jungle babblers, Delacour’s tribe Pellorneini, has long been subject to reversals of opinion, suggestive of a still-poor understanding of natural relationships. At the unstable boundary of genera Trichastoma and Pellorneum, groups of taxa usually taken to comprise a continental species tickelli and an insular species pyrrogenys have shifted from positions in separate genera to being neighbours in first one and then the other of these two. A fresh morphological analysis and newly described vocalizations show them to be one another’s probable closest relative, potentially conspecific but due to limitations on the allowable use of vocalization evidence among allopatric populations, for the time being at least, kept as separate entities.... |

| Hypotheses of family phylogeny are summarized up to date, and amendments made to the treatment by Delacour (1960) of Chloropsis and Irena in Peters’s Check-list of Birds of the World (Mayr & Greenway, 1960), at and below species level. Revision of species-limits within C. cochinchinensis (Gmelin, 1789) and C. aurifrons (Temminck, 1829) as defined in Delacour (1960) restores three ultra-taxa to species rank, boosting the global list of leafbird species to 11. Certain range and nomenclatural issues are resolved, including re-designation of the type locality of Turdus cochinchinensis, type species of Chloropsis. A new subspecies name is introduced as an outcome. |
