“…In this study, we have conducted genomic analysis on museum specimens collected ∼70 years ago to investigate the evolutionary relationships of Woolly-necked storks, whose taxonomic status has been a topic of uncertainty (Sundar 2020). To our knowledge, this is the first study to produce genomic resources for the Woolly-necked storks and employ the genomic data to examine the existing taxonomy, which has solely relied on morphological data to date.…”

“…The taxonomic classification of Woolly-necked storks has been a matter of ongoing debate and uncertainty, with limited knowledge about the diversity of these birds across their extensive distribution (Mlodinow et al 2022). Such ambiguity holds potential implications for the conservation of these species (Sundar 2020). African and Asian Woollynecks were previously regarded as a single species until 2010.…”

The availability of large-scale genomics data for current research in evolutionary biology has enabled a comprehensive examination of the intricate interplay between diverse evolutionary processes associated with speciation. Despite these advancements, the genomic basis of taxonomic classification remains challenging in many species, one such example being the Woolly-necked storks(Ciconia sps.). The Woolly-necked storks are distributed in Asia and Africa with a taxonomic classification(C. episcopus and C. microcelis)that has been a matter of contention and ambiguity. Asian and African Woollynecks were just recently recognized as different species based on their morphological differences, however genetic/genomic studies on Woolly-necked storks are lacking. In this study, we have used ∼70-year-old museum samples to explore the taxonomy and evolution of the Woolly-necked storks. We used a whole-genome sequencing strategy and generated 13.5 million single nucleotide polymorphisms (SNPs) that were polymorphic among populations of Asian and African Woollynecks. Our study has revealed that Asian and African Woollyneck are genetically distinct, consistent with the current taxonomic classification based on morphological features. However, we also found a high genetic divergence between the Asian subspeciesC. e. neglectaandC. e. episcopussuggesting this classification harbors cryptic diversity that requires a detailed examination to explore processes of ongoing speciation. Because taxonomic classification directly impacts conservation efforts, and there is evidence of declining populations of Asian Woollynecks in Southeast Asia, our results suggest populations-scale studies are urgent to determine the genetic, ecological, and phylogenetic diversity of these birds. Moreover, our study also provides historical genomic resources to examine genomic signatures of local adaptation associated with the distribution, ecology, and evolution of African and Asian Woollynecks.

“…Intraspecific brood parasitism is also a behavioural adaptation recorded in over 200 species (Lyon and Eadie 2008). Others still may opportunistically use other species' empty nests (e.g., Sundar et al 2022; Thompson et al 2019).…”

Nest-building is an energetically expensive activity for birds. Consequently, some species opportunistically use other species' nests. The Hamerkop Scopus umbretta, an endemic sub-Saharan African waterbird, constructs one of the largest nests of any bird in the world. Little is documented on the role of Hamerkop nests in the breeding biology of other avian species. Therefore, we assessed this from the literature and first-hand observations to determine which species use Hamerkop nests and their associated behaviours. We found at least 20 avian species using Hamerkop nests for breeding in 18 African countries. The Barn Owl Tyto alba was the most commonly reported species using Hamerkop nests. Six species actively usurp nests from Hamerkop pairs. Nine species nested inside the nest chamber, and eight nested on top of the structure. This highlights the role of Hamerkop nests in other avian species' breeding.
