Autumn 2025 – Day 1 of bird ringing
The nets are open, the team is ready, and the first 10 birds of the season have already a ring. Looking forward to discovering what surprises migration brings this season. #birdringing #avianmigration #Antikythera

Simulating and Analysing Seabird Flyways: An Approach Combining Least‐Cost Path Modelling and Machine Learning
Aim We develop and test a cost framework to simulate the flyways of migratory seabirds, considering various environmental factors such as wind support, crosswind, travel distance, and food availabil...

Figure 1 in Lameris et al. (2025): "Wintering centroids (median positions) of individual birds per year, general migration routes and study sites in the Arctic. Dots, squares and diamonds show wintering centroids and inverted triangles show study sites, with in (a) sanderlings breeding at Zackenberg (pink) and red-necked phalaropes breeding at Ammarnäs (light blue) and Slettnes (yellow), (b) Arctic skuas (dots) breeding at Kongsfjorden (red) and Slettnes (yellow), long-tailed skuas (squares) breeding at Ammarnäs (light blue) and rough-legged buzzards breeding at Kolguev Island (green dots), and (c) barnacle geese (green diamonds) and greater white-fronted geese (green dots) breeding on Kolguev Island, barnacle geese breeding in Kongsfjorden (red diamonds), pink-footed geese breeding in Adventdalen (dark blue dots) and tundra swans breeding at the Malozemelskaya tundra (orange dots). Broad migration routes are indicated with dotted lines and colours similar to the study sites and wintering centroids. In (c), barnacle geese breeding on Kolguev Island follow the northern green route while greater white-fronted geese use the entire green route. The dotted line indicates the Arctic circle. Photos by Tim Sudlow (tundra swan), Nick Goodrum (pink-footed goose), Jasper Koster (barnacle goose), Nick Athanas (sanderling, greater white-fronted goose), John Quine (Arctic skua), Matti Suopajärvi (rough-legged buzzard) and Alaska Region U.S. Fish & Wildlife Service (red-necked phalarope, long-tailed skua).

Last year the swifts didn't return for roost.
In dedication I post this vid from 2019 and a repost with a track by Aesop Rock depicting it's mystical effect on him when he saw it himself.

Figure 1 in de Vries et al. (2025): "Locations of the main study colonies for the three subpopulations (a), development of the barnacle goose Russia/Germany and Netherlands flyway population and North Sea and Baltic Sea subpopulations (b) based on population counts, and an overview of the density in ringing effort in the three subpopulations (c). The Barents Sea subpopulation is represented here in red, the Baltic Sea subpopulation in yellow, while the North Sea subpopulation is represented in blue. Data on population sizes were collected from van der Jeugd et al. (2009), Koffijberg et al. (2020), Isaksen (2020), Nagy et al. (2021) and Jensen et al. (2022). Since flyway and subpopulation counts are unavailable after 2006 and incomplete for the Baltic Sea after 2002, these have been supplemented with sizes estimated in an integrated population model, indicated by diamond-shaped dots (Baveco et al., 2020; Jensen et al., 2022)."
