'A single sample from the extinct Philippine subspecies A. a luzonica clustered with A. a. gillae, hinting at the potential for a more recent separation between them than from A. a. antigone and A. a. sharpii, even though A. a. sharpii is closer geographically. '

"We compared new D. hottentottus material from Mt. Kinabalu (Sabah), Mt. Mulu (Sarawak), the Kelabit Highlands (Sarawak), Maratua Island (Kalimantan), Mt. Talamau (Sumatra), and Siberut Island (Sumatra) with existing ND2 sequences (Fig. 4b). The tree indicates that D. hottentottus as currently classified is paraphyletic with the Balicassiao D. balicassius (Linnaeus, 1766). To simplify discussion of the tree, we have divided the taxa into four clades based on topology.'

"Clades 3 and 4 comprise several Philippine taxa. Clade 3 includes D. balicassius of the northern Philippines and D. h. samarensis and D. h. striatus of the southern Philippines. The Palawan subspecies D. h. palawanensis constitutes Clade 4. Vaurie (1949) distinguished D. hot- tentottus from D. balicassius based on the appearance and complexity of feather ornaments. Genetic data, however, suggest a close relationship between D. hottentottus subspecies of the southern Philippines and D. balicassius of the northern Philippines. It is possible, however, that this closeness arises as a result of mtDNA introgression. A more extensive set of comparisons using nuclear loci is required to confirm D. hottentottus relationships within the Philippines Islands."

"Based on our comparisons, however, we suggest the following (limited) taxonomic changes:
1. Elevate short-tailed Drongo D. h. striatus (including D. h. samarensis) of the southern Philippines to species status or include it as a subspecies of D. balicassius.
2. Elevate Palawan Drongo D. h. palawanensis (probably including D. menagei and D. h. cuyensis) to species status. Rocamora et al. (2009) present arguments for treating D. menagei as a separate species."

Halley, Matthew R. (2022) A new subspecies of Black-headed Tailorbird Orthotomus nigriceps (Cisticolidae) and clarication of age-related plumage sequences. Journal of Asian Ornithology [formerly Forktail] 38: 119-124.

Abstract
The Black-headed Tailorbird Orthotomus nigriceps was described from Mindanao, southern Philippines, but few specimens are available. Overlooked study skins from the islands of Dinagat and Siargao, east-central Philippines, in the Delaware Museum of Nature & Science shed light on sexual and geographic variation in this species. Adult specimens from Dinagat and Siargao have paler plumage on the belly, and brighter and yellower plumage on the sides, flanks and tail, than O. nigriceps specimens from Mindanao. However, phylogenetic analysis of mitochondrial DNA sequences (ND2) does not show appreciable divergence between these populations. Based on the phenotypic distinctiveness of specimens, I describe the populations from Dinagat and Siargao as a new subspecies. Furthermore, a survey of all 55 study skins that exist in databased collections revealed that, on all three islands, adults of both sexes have black chins, throats and upper breasts. Thus, O. nigriceps is not sexually dichromatic in the adult plumage, contrary to most published accounts.
