AbstractBird ringing is used for a long time for scientific investigation of migration routes and to better understand breeding events as well as population ecological aspects. It is applied as an inexpensive method although the well-known and major disadvantage of bird ringing is the usually low response rate. In the case of rarer species such as the Red-Footed Falcon (RFF), however, this quota could be higher due to the exclusivity and greater attention of observers. Motivated by own field observations of color-ringed RFF south of Brunswick, Germany in 2019 and no clear and comprehensive publication of verified additional recoveries and ringings, we did further research regarding this issue by following methods: 1) Contacting European Bird Ringing Centers and associated projects, 2) Query and comparison of files with the three national German Bird Ringing Stations, 3) Expanded literature research, 4) Evaluating reports in the citizen science platform ornitho.de, 5) Checking websites of ringing projects (in particular satellite tracking programs) and 6) Own observations.Surprisingly, this study revealed 18 recovered RFF ringed in foreign countries (14 Hungary, 3 Italy, 1 Romania (GPS tracked bird)) during migration or post-nuptial pre-migration time. Additionally, 1 RFF that was caught and ringed in Germany was recovered abroad.This result updates and increases the number of recoveries of RFF in Germany compared to the actual published state on the order of 18 (so far none) and on the order of 6 concerning ID-encoded RFF (GPS-bird excluded) compared to documentation state of the three Bird Ringing Centers in Germany (so far 3 at Beringungszentrale [BZ] Hiddensee, 1 at Institut für Vogelforschung [IfV] Heligoland). Our research and evaluation of raw data succeeded to a 100% identification rate of the bird’s origin countries (n=18) while the rate of ID-encoded RFF by color ring codes revealed 58.8% (n=10, GPS-bird excluded). The reported-by-observer response rate was 41.2%. Interesting data of about the phenology, age and origin of the RFF recovered in Germany are presented. Questions and considerations about the recent reporting system of ringed birds and the increased numbers of RFF during the last years in Germany are discussed.

Predicted flight trajectories differ depending on which orientation cues are used by migrating birds. Results from radar and satellite tracking of migrating birds can be used to test which of the predicted trajectories shows the best fit with observed flight routes, supporting the use of the associated orientation mechanism. Radar studies of bird migration at the Northeast Passage and the Northwest Passage support the occurrence of migration along sun compass routes in these polar regions. In contrast, satellite tracking of Brent geese (Branta bernicla) migrating from Iceland across Greenland and from Northwest Europe to Siberia show routes that conform most closely with geographic loxodromes, but which are also profoundly influenced by large-scale topography. These evaluations are discussed in relation to the adaptive values of different routes in different parts of the world. Sun compass routes are favourable mainly for east-west migration at high latitudes. For east-west migration at mid and high latitudes magnetic loxodromes are more favourable than geographic loxodromes in certain regions while the reverse holds in other regions. The geometry of migration routes, as recorded by radar and satellite tracking, may be important for understanding the evolution of the complexity of birds' orientation systems, and for providing clues about the orientation mechanisms guiding the birds on their global journeys.

Satellite-tagging is increasingly becoming a powerful biotelemetry approach to obtain remote measurement through tracking free-living cetaceans, which can fill knowledge gaps on cetaceans and facilitate conservation management. Here, we made a first biologging attempt on baleen whales in Chinese waters. An adult Bryde’s whale in the Beibu Gulf was tagged to investigate potential occurrence areas and migration routes of this poorly studied species. The whale was satellite-tracked for ~6 days with 71 filtered Argos satellite locations, resulting in a linear movement distance of 464 km. At each satellite-tracking location, the water depth was measured as 42.1 ± 24.8 m on average. During the satellite-tracking period, the whale’s moving speed was estimated at 5.33 ± 4.01 km/h. These findings expanded the known distribution areas of Bryde’s whales in the Beibu Gulf and provided an important scientific basis for the regional protection of this species. We suggest that fine-scale movements, habitat use, and migratory behavior of Bryde’s whales in the Beibu Gulf need more biotelemetry research, using long-term satellite-tracking tags and involving enough individuals. Furthermore, the genetic relationship and possible connectivity of Bryde’s whales in the Beibu Gulf and adjacent waters should be examined.

Most migratory birds depend on stopover sites, which are essential for refueling during migration and affect their population dynamics. In the East Asian–Australasian Flyway (EAAF), however, the stopover ecology of migratory waterfowl is severely under-studied. The knowledge gaps regarding the timing, intensity and duration of stopover site usages prevent the development of effective and full annual cycle conservation strategies for migratory waterfowl in EAAF. In this study, we obtained a total of 33,493 relocations and visualized 33 completed spring migratory paths of five geese species using satellite tracking devices. We delineated 2,192,823 ha as the key stopover sites along the migration routes and found that croplands were the largest land use type within the stopover sites, followed by wetlands and natural grasslands (62.94%, 17.86% and 15.48% respectively). We further identified the conservation gaps by overlapping the stopover sites with the World Database on Protected Areas (PA). The results showed that only 15.63% (or 342,757 ha) of the stopover sites are covered by the current PA network. Our findings fulfil some key knowledge gaps for the conservation of the migratory waterbirds along the EAAF, thus enabling an integrative conservation strategy for migratory water birds in the flyway.
