“…The Chinese Crested Tern Thalasseus bernsteini has less than 50 individuals (Chen et al, 2015) and is the most critically endangered seabird species in Asia (Hung et al, 2018). This species is not just one of Asia's most endangered species, but it is also one of the world's most endangered seabird species, with only a small breeding population of approximately 100 individuals (Gu et al, 2021;Lu et al, 2020). In their study, Lu et al (2020) discovered a worldwide population of this species that exceeded 100 for the first time in history, with breeding grounds restricted to East China and the Yellow Seas.…”

Climate change is not something that has never happened before. However, it has recently been reported that climate change has affected living things such as humans, animals and plants. Among the animals that may be vulnerable to the effects of climate change are migratory bird species. Therefore, this review paper will emphasise the checklist of migratory bird species found to be affected by climate change. Data for bird migration species in Asia are obtained from the Birdlife Data Zone. At the same time, the data for Global land surface temperature (1910-2020) and Asia land surface temperature (1910-2020) were taken from National Oceanic and Atmospheric Administration for Environmental information. These papers showed that climate warming could affect species differently, but there are still species from certain populations not affected at all. This paper also reviewed that approximately 169 species of migratory birds in Asia are affected by climate change and severe weather. Of the total, 5 species (2.96%) are critically endangered, 8 (4.73%) endangered, 21 (12.43%) vulnerable, 27 (15.98%) near threatened and 123 (63.91%) least concern.

Brown Skua (Stercorarius antarctica-lonnbergi) and South Polar Skua (Stercorarius maccormicki) aoccur in the Antarctic Peninsula and are sympatric in distribution over about 500km. In this region hybridization between a male of South Polar Skua and a female Brown Skua producing a viable and fertile offspring has been reported. The present study aims to review the evolutionary history of South Polar Skua and Brown Skua to better understand the hybridization process between these species. To assess the evolutionary history between these species, 67 DNA samples were sequenced for AK1 locus, 70 samples for RAG1 locus and 96 samples for Cytb locus, sampling in King George and Elephant Island. Cytb and RAG1 loci showed greater genetic diversity in samples from hybrid birds than those of non-hybrid individuals and may re ect the outcome of the heterosis. Overall Brown Skua had higher genetic diversity than South Polar Skua. In addition, South Polar Skua showed probable populational expansion signals, in contrast to Brown Skua that showed population stability through time. However, our phylogenetic analysis did not corroborate the reciprocal monophyly between these species. Thus, South Polar Skua and Brown Skua show incomplete lineage sorting, indicating these species are a single taxonomic group.
