“…All individuals migrated south‐westward during autumn to nonbreeding sites on the East Asian mainland, a pattern observed in the majority of migratory East Asian songbird species (Bensch et al, 2022 ; Heim, Heim, Beermann, et al, 2020 ; Heim, Pedersen, et al, 2018 ; Yamaura et al, 2017 ). An exception to this pattern is the Blue‐and‐white Flycatchers Cyanoptila cyanomelana co‐occurring with yellow‐throated buntings at our study site, which were recently found to migrate southward to the Philippines (Heim, Antonov, et al, 2022 ).…”

Basic information on the ecology of species is key for their conservation. Here we study the ecology of the little‐known yellow‐throated bunting Emberiza elegans based on a multi‐year study on its breeding grounds in the Russian Far East. For the first time in this species, we quantified breeding habitat parameters, calculated sex‐specific apparent survival, and determined individual nonbreeding locations using light‐level geolocation. We found that the habitat around song posts of male yellow‐throated buntings is characterized by tree and shrub layers on richly littered moist ground. Habitat use overlaps with co‐occurring Tristram's Buntings Emberiza tristrami and Black‐faced Buntings E. spodocephala , but territories differ especially in tree cover and litter cover. Based on 4 years of color‐ringing data of 72 individuals, we calculated an apparent survival rate of 36%, with higher survival estimates for male than for female yellow‐throated buntings. We found no effect of carrying a geolocator on survival. We retrieved six geolocators from males. All birds migrated south‐westward during autumn and spent the nonbreeding season at locations in China 700–1700 km away from their breeding sites. At least two individuals spent the boreal winter outside of the known range in northern or central China. Birds left the breeding area between early October and early November and returned between mid‐March and mid‐April. Our data on habitat use, survival rate, and migratory connectivity will help to assess threats to the populations of this enigmatic species, which might include habitat loss due to forest fires on the breeding grounds, and unsustainable harvest for consumption during the nonbreeding season.

“…Overall, our data suggests that the tracked Arctic Warbler was almost constantly on the move, not a single site during the annual cycle has been used for more than two months. This differs strongly from other East Asian songbird migrants, for which long autumn stopovers of up to three months and very long stationary periods during the boreal winter ( ve-six months) were documented (Heim et al 2018(Heim et al , 2020(Heim et al , 2022. Most likely, Arctic Warblers are moving further to track seasonal peaks of food abundance -a similar pattern with several consecutive wintering sites was found in the closely-related Willow Warbler Phylloscopus trochilus wintering in Africa (Lerche-Jørgensen et al 2017; Sokolovskis et al 2018).…”

“…from the Asian mainland to islands in the Indo-Paci c has previously been reported for one other landbird species, the Blue-and-white Flycatcher breeding in the Russian Far East(Heim et al 2022). The non-breeding locations of the tracked Arctic Warbler breeding in Siberia were situated further west compared to the two individuals from Alaska(Adams et al 2022).…”

Little is known regarding the migration routes of songbird populations breeding in Siberia. Here we provide the first geolocator tracking data for an Arctic Warbler breeding in Central Siberia and compare its movements with eight long-distance ring recoveries of this species. In autumn, the tracked individual migrated eastward to a stopover site in eastern Siberia, before migrating southward through Taiwan to its non-breeding sites in the Philippines and Indonesia. During spring migration, the bird spent at least one month at stopover sites in Mongolia, before migrating to its breeding site in June. Ring recovery data confirmed the movement between the Central Siberian breeding grounds and stopover sites in northern Mongolia.

“…A few species deviate from these general patterns. For example, a Blue‐and‐white Flycatcher Cyanoptila cyanomelana was tracked from its breeding grounds in mainland Russian Far East to a wintering site on the islands of the Philippines (Heim et al, 2022 ), and Arctic Warblers Phylloscopus borealis breeding in Alaska and wintering in Philippines and Palau might follow a loop migration pattern, taking a mainland route during autumn migration, but the island route during their spring migration (Adams et al, 2022 ).…”

Until recently, the migration strategies of small landbird species of the East Asian flyway were relatively poorly studied in comparison with those of the European-African and the American flyways (McKinnon & Love, 2018). This changed considerably during the last decade following the development of tracking techniques based on light levels (see Yong et al., 2021 for review). Tracking studies of East Asian landbirds showed that while a few species of small-and medium-sized species undertake direct sea crossings (Koike et al., 2016) most generally avoid prolonged marine transits, performing detours around water barriers even when they start
