Would not be BOU these day as as they defer to the IOC.

Decision of SACC, that's their business, so don't care. The only thing i want to know is if the elevation of Herpetotherinae to family rank is justified or not. If yes, I would act accordingly

I'm not saying the opposite, my own list incorporates arbitrary decisions, however researchers who suggest this or that recommendation are based on evidence, in principle
If you manage a list, I would be interested in seeing your work |=)|

American Kestrel (Falco sparverius) genoscape: implications for monitoring, management, and subspecies boundaries
Identifying population genetic structure is useful for inferring evolutionary process and comparing the resulting structure with subspecies boundaries can aid in species management. The American Kestrel (Falco sparverius) is a widespread and highly diverse species with 17 total subspecies, only 2 of which are found north of U.S./Mexico border (F. s. paulus is restricted to southeastern United States, while F. s. sparverius breeds across the remainder of the U.S. and Canadian distribution). In many parts of their U.S. and Canadian range, American Kestrels have been declining, but it has been difficult to interpret demographic trends without a clearer understanding of gene flow among populations. Here we sequence the first American Kestrel genome and scan the genome of 197 individuals from 12 sampling locations across the United States and Canada in order to identify population structure. To validate signatures of population structure and fill in sampling gaps across the U.S. and Canadian range, we screened 192 outlier loci in an additional 376 samples from 34 sampling locations. Overall, our analyses support the existence of 5 genetically distinct populations of American Kestrels—eastern, western, Texas, Florida, and Alaska. Interestingly, we found that while our genome-wide genetic data support the existence of previously described subspecies boundaries in the United States and Canada, genetic differences across the sampled range correlate more with putative migratory phenotypes (resident, long-distance, and short-distance migrants) rather than a priori described subspecies boundaries per se. Based on our results, we suggest the resulting 5 genetically distinct populations serve as the foundation for American Kestrel conservation and management in the face of future threats.

Population genetics and phylogeography of North American Merlins (Falco columbarius) in the post-DDT era
Ibis (advance online publication)
doi: 10.1111/ibi.13182
In North America, the population genetic structure of many raptor species has been shaped by patterns of post-glacial population expansion and anthropogenic forces, such as the widespread use of the organochlorine pesticide DDT during the mid-20th century. While common themes of post-glacial avian population expansion have emerged, little is known about the genetic impacts of DDT on raptor species that experienced a population bottleneck but were not the focus of conservation efforts. We investigated how the combination of post-Pleistocene environmental change and the DDT-era population bottleneck have influenced the contemporary population structure of Merlins Falco columbarius in North America. We genotyped migrating Merlins across North America (n = 272), at 23 polymorphic microsatellite loci and generated sequence data for a 569-base pair segment of the mitochondrial control region. We used hierarchical analysis of molecular variance, pairwise Fst/ϕst comparisons, and Bayesian clustering analyses to assess genetic differentiation between individuals from eastern and western North America, distinct migratory flyways, and three recognized North American subspecies. Across all analyses, we found low or no population differentiation, suggesting North American Merlins are largely comprised of one panmictic population showing evidence of a post-glacial population expansion with little genetic differentiation detected between regions. Furthermore, we did not detect a contemporary signal of a genetic bottleneck that could have resulted from the DDT-era population decline with the markers used in this study. Consistent with other avian species, we found a correlation between allele length variation at a microsatellite isolated from the 3’ UTR of the ADCYAP1 gene and migratory versus sedentary characteristics in Merlin subspecies. We detected two common mitochondrial control region haplotypes in the geographic regions sampled, a unique pattern among other wide-spread North American raptor species. This study furthers our understanding of the genetic and demographic history of Merlins in North American and can inform future genomic studies on this species.

Phylogenomic insights into the polyphyletic nature of Altai falcons within eastern sakers (Falco cherrug) and the origins of gyrfalcons (Falco rusticolus)
Scientific Reports 13: 17800
doi: 10.1038/s41598-023-44534-4
The Altai falcon from Central Asia always attracted the attention of humans. Long considered a totemic bird in its native area, modern falconers still much appreciated this large-bodied and mighty bird of prey due to its rarity and unique look. The peculiar body characteristics halfway between the saker falcon (Falco cherrug) and the gyrfalcon (F. rusticolus) triggered debates about its contentious taxonomy. The weak phylogenetic signal associated with traditional genetic methods could not resolve this uncertainty. Here, we address the controversial evolutionary origin of Altai falcons by means of a genome-wide approach, Restriction-site Associated DNA sequencing, using sympatric eastern sakers falcons, allopatric western saker falcons and gyrfalcons as outgroup. This approach provided an unprecedented insight into the phylogenetic relationships of the studied populations by delivering 17,095 unlinked SNPs shedding light on the polyphyletic nature of Altai falcons within eastern sakers. Thus we concluded that the former must correspond to a low taxonomic rank, probably an ecotype or form of the latter. Also, we found that eastern sakers are paraphyletic without gyrfalcons, thus, these latter birds are best regarded as the direct sister lineage of the eastern sakers. This evolutionary relationship, corroborated also by re-analyzing the dataset with the inclusion of outgroup samples (F. biarmicus and F. peregrinus), put eastern sakers into a new light as the potential ancestral genetic source of high latitude and altitude adaptation in descendent populations. Finally, conservation genomic values hint at the stable genetic background of the studied saker populations.

The paper uploaded in this researchgate page is Mindell & al, 2018, not Fuchs 2015. Anyone have the paper Fuchs & al (2015) ? I would like to check something about Falco columbarius
