This species was found in the lighthouse area on May 14. This is the first record for Lista BO, and second for Norway. The first one was seen in 2000 in Porsanger (Troms og Finnmark).
Report from spring 2023
The station has been run for a total of 88 days from March 15 until June 10. 13 mist-nets have been currently used on the standardized (138 meters). The result was a lower number of birds than normal.
Only 44 individuals of Willow Warbler were ringed during the spring. This is 65% under average and the second worst record since 1990.
This species was ringed 60% over average and reached record numbers in observations in spring 2023.
Only 2 Great Skuas were seen in the whole season (average is 20). A worse year than this was in 1996 with no individuals seen in spring.
The total of birds ringed this spring has been 16,1 % under average: 692 birds ringed (average for spring is 825) of 45 different species, 6 more than last year.
The average temperature has been 0.3°C lower than normal (from March 1 to June 10). The precipitation was over the normal in March, April and May, especially in March when it rained almost double than usual. June was however very dry, with no precipitation until the end of the campaign. There have been 22 days without ringing, which is the same number as last year but more days than previous years (17 days in 2021 and 2020).
The number of ringed birds has been 16,1% under average and the number of species has been higher than last year. The "top 5 species" in the nets have been Robin (111), Blackbird (56), Chiffchaff (55), Linnet (48) and Siskin (45). This is only the second time since 1990 that Willow Warbler is not on the top 5 species.
Most warblers have shown very low numbers. Willow Warbler and Common Whitethroat have been ringed 65% and 59% respectively under average, showing both some of the lowest numbers since 1990. Garden Warbler and Lesser Whitethroat have also been ringed in low numbers, 11% and 22% respectively under average. However, Chiffchaff and Blackcap have shown high numbers, being ringed 60% and 35% respectively over average.
The number of Wrens ringed this spring have been the highest ever with a total of 20 individuals (average is 8). The large thrushes were ringed in low numbers as it has been happening the last years. Song Thrush, Blackbird and Fieldfare have been ringed 48%, 22% and 76% respectively under average this season.
The Northern Wheatear was ringed 20% down average, probably being affected by the very low numbers last year (48% under average, being the lowest year since 2003). The Common Redstart was ringed in high numbers this season and the Robin has been ringed in normal numbers as last year. A Thrush Nightingale was ringed in April, being the 6th record in spring since 1990. Two Stonechats were caught in the nets and there have been two possible breeding pairs in the area that finally disappeared in the beginning of May, after been seen in the same spot for some weeks.
Dunnock and Meadow Pipit were ringed under average, while White Wagtail showed good ringing numbers.
The number of finches showed in general very low ringing results, including Chaffinch, Greenfinch and Lesser Redpoll. The same happened to Yellowhammer. Linnet and Siskin were the only finches ringed over average. Spring 2023 was the fifth one in a row without any Rosefinch in the nets.
The breeding Wheatears have been well monitored in the station area in 2023. More staff was available this spring and based on the observations, we assume that the population was low and that it has not been a good breeding season, with only 9 nests found in the lighthouse area (Gunnarhaug, Vågsvollvåien, Vågsvollvika). From these, one of them failed, 5 had unknown numbers of eggs (could not reach the nest) and two of them had only 1 chick left at the age of 7 days. This is not surprising, considering that this species was caught 48% and 20% under average in spring 2022 and 2023, and that several nests close to the study area were predated in 2023 by a stoat.
No Tree or House Sparrows have been ringed at all this spring, being the 4th and 2nd time happening this ever.
From January to June, 191 species were recorded in the station area (three more than last year).
Some species have been recorded in very high numbers. Eurasian Wigeon, Northern Pintail, Common Teal, Velvet Scoter, Common Sandpiper, Black Guillemot, Common Diver, Yellow-billed Diver, Red Kite, White-tailed Eagle, Red-backed Shrike, Rook, Hooded Crow, Barn Swallow, Chiffchaff, Wren, Blackbird and Goldfinch showing the highest or second highest numbers since we started counting in 1990.
Gadwall, Red-necked Grebe, Black-legged Kittiwake, Black-headed Gull, Common Tern, Arctic Tern, Great Skua and Fulmar were, on the other hand, seen in numbers between 61% and 91% below average. Pomarine Skua was not seen at all, happening the same in 1990.
For many waders, the number of observations has become much lower during the last 7 years. However, this spring it has been different. Lapwing, which has been showing very low numbers the last years, showed this spring the highest numbers since 2013. Whimbrel, Sanderling, Woodcock, Wood Sandpiper and Greenshank were registered with much higher numbers than normal. In addition, 2 individuals of Little Stint were seen (first time since 2015) and 4 Red-necked Phalaropes were seen migrating north-west (7th time this species is observed in spring). Common Sandpiper showed its 2nd best year ever. In addition, Pied Avocet and White-tailed Lapwing were seen in the area. One or two pairs of Lapwings have stayed in the area (Porsan) but land farming did not let them continue breeding.
There have been a few notable or rare species in the area during the spring. One species is the first record at the station, and second for Norway, the White-tailed Lapwing. The most special observations otherwise were Mandarin Duck, Smew, Pied Avocet, Red-necked Phalarope, Caspian Gull, Great Egret, Pallid Harrier, Montagu´s Harrier, Red Kite (2nd best year), Black Kite, European Bee-eater, Golden Oriole, Firecrest, Thrush Nightingale and Serin.
The bird station continued to guide schools and private visitors in the spring in collaboration with the Visitor Center Wetland Lista. A total of 6 groups / schools have guided by the bird station.
Sara Carrillo (Spain), Oddvin Lund (Norway), Bård Olsen (Norway), Karina Tjørve (Norway) and Gunnar Gundersen (Norway) have been volunteers at the station and collaborated with Diogo Portela (main counter) and Rubén Piculo (main ringer), as well as Aïda López who has been responsible for the work at Lista Bird Observatory during spring 2023.
