The annual report for 2023 is available! Dunnock The Dunnock had a very low year at the two bird observatories in 2023. Compared to the period before 2017-18, the numbers have generally been low at both stations. Common Greenshank In the phenology index, the Common Greenshank has advanced its spring migration by 4.6 days. Six waders are included in the index. Of these, two species have advanced their migration significantly (Dunlin and Greenshank). By the end of 2023, the standardized trapping scheme at Jomfruland and Lista Bird Observatories (BO) have been carried out for 34 years. This report presents both long-term trends and data from the 2023 trapping season for 49 species included in the scheme. In addition, observation data for selected species are presented. The trends we present apply to both variations in number (population) and migration time (phenology). (The annual report 2023 from Jomfruland and Lista can be read in Norwegian HERE) Low trapping numbers The ringing numbers for 2023 ended up much below average (1990–2022) for both observatories. A total of 1 159 birds were trapped at Jomfruland BO in spring, while 4 020 birds were trapped in autumn. This is 28,7 % and 23,9% below average, respectively. Corresponding numbers at Lista BO were 692 birds in spring, and 2 003 birds in autumn, which is 16,1 % and 49,7 % below average, respectively. The autumn figures at Lista was by far the lowest since monitoring began in 1990. Arrival was as expected In our phenology index for the spring, we have an estimated trend showing that 30 selected migratory bird species now arrive on average 3,4 days earlier than they did when monitoring began in 1990. Arrival in 2023 was very close (0,2 days earlier) to the expected in relation to the development of our index. A few species that normally arrive in early May were delayed. As an example the Willow Warbler arrived as much as 11 days later than expected. For most of the species there were small changes. 25 our of 30 species arrived with only +/- 4 days from the days they were expected. The migration counts were more positive than the ringing numbers The observations data (from migration counts) the results for 2023 (especially autumn) and the long-term trends were significantly more positive than in the standardized trapping. This applies especially to non-passerines. Many species of shorebirds and ducks had very high numbers in the 2023 autumn. The majority of these species breed far north and east (Arctic tundra). Important and unique monitoring The monitoring at the bird observatories is unique in the Norwegian context providing information on the phenology (migratory route) of our most common passerines. This makes us able to see how climate change affects bird migration. Both BirdLife Norway and the bird observatories want to contribute to knowledge-based management. Reporting and dissemination of the results from the work carried out at the bird stations is considered an important part of this.
