Blue Tit All the tits have been ringed in very low numbers this autumn, between 70% and 97% down average. Blue Tit, which is the species caught in higher numbers in the autumn at Lista, was caught 85% under average, catching the lowest number since 1990. Report from autumn 2024
Weather The average temperature has been higher than normal throughout the autumn, with 0.6°C higher than normal from July until October, having an extremely warm early September and being October 1.6° C above normal. The precipitation has been higher in July and lower in September, but in average have been normal. There have been many days with strong winds or hard rain, avoiding the use of nets for 31 days (compared to 39 days in 2023 and 29 in 2022). Ringing The numbers of ringed birds this autumn have been 66% down average and clearly the weakest year since the start of monitoring in 1990. Catching numbers were 4 less species than in autumn 2023. The "top 5 species" in the nets have been Blue Tit (152), Willow Warbler (151), Eurasian Wren (131), Goldcrest (102) and Common Blackbird (88). 85% of the species that are usually caught in the nets (excluding those with low seasonal trapping numbers (< 5 ind.).) were caught between 35% and 100% down average. Only 2 out of the 46 most common trapped species, were caught in positive numbers. That is Eurasian Wren (13% above average) and Chiffchaff (42% above average). The larger thrushes have been ringed in low numbers as the last years, except for Blackbird which was caught in relatively normal numbers (-4%). Song Thrush, Redwing and Fieldfare have been ringed between 57% and 82% down average. Other species of small thrushes such as Robin, Whinchat and Northern Wheatear also had a very poor season being respectively ringed 59%, 35% and 45% below average numbers. Pipits and Wagtails have been ringed between 66% and 100% below average numbers, except for White Wagtail that was caught 19% down average. In addition to the bad results, this is the first time that no Yellow Wagtails have been caught in the last 16 years. All the tits have been ringed in very low numbers, between 70% and 97% down average. Blue Tit, which is the species caught in higher numbers in the autumn at Lista, was caught 85% under average, catching the lowest number since 1990. Also, all the common warblers except for the Chiffchaff (mentioned above) have been ringed in dramatic low numbers, especially Willow Warbler, Blackcap, Garden Warbler, Lesser Whitethroat and Common Whitethroat, been ringed between 51% and 93% below average. Most of them such as Willow Warbler, Blackcap, Garden Warbler and Common Whitethroat have shown the lowest trapping numbers since 1990. Finches and buntings have not been different, unfortunately. They have shown very low ringing numbers, except for Linnet and Reed Bunting that have been caught respectively 16% and 19% down average. Chaffinch, Brambling, Bullfinch, Greenfinch, Redpoll and Siskin have been ringed between 70% and 100% below average. An Arctic Redpoll was caught in the nets this autumn. We have continued catching and colour-ringing Rock Pipits with playback and clap-nets with worms. Only 3 individuals have been ringed by the traps this autumn. In the standardized ringing we have also continued colour ringing Whinchat, Stonechats, Wheatear, White Wagtail and Rock Pipit. Owl’s playback has been used during the nights in autumn when weather was suitable. However, we did not catch a single owl on the non-standardized ringing. Observations From 1st of January to 15th November, 240 species have been recorded in the observatory area (4 less than last year). There have been some species this autumn that have been registered in very high numbers, such as, Mute Swan, Black-legged Kittiwake (3rd best), Sooty Shearwater (3rd best), Manx Shearwater, Common Gull (3rd best), Red-backed Shrike (3rd best) and European Goldfinch. Eurasian Wigeon, Wryneck and Siskin show among the best 5 years since 1990. Grey Heron, Yellow-browed Warbler and Common Blackbird show record numbers this autumn. Something extraordinary happened on November 8. After a very strong nocturnal migration, we saw in the morning big flocks of thrushes, mainly Blackbirds, coming back from the sea (probably after they met bad weather before reaching land). That morning 37.500 Blackbirds were estimated to cross Lista, while average for the whole autumn is 1040. However, this season has been characterized by the very low numbers in most of the passerine species. Many of the observations show similar results as the ringing numbers. Coal Tit, Crested Tit, Willow Tit and Blue Tit have been seen between 76% and 100% down average. Willow Warbler, Blackcap, Garden Warbler, Lesser Whitethroat and Common Whitethroat have been seen between 42% and 82% down average. Garden Warbler have shown record lowest numbers with 17 observations (average 90). Song Thrush, Fieldfare, Spotted Flycatcher, European Pied Flycatcher, Common Redstart, Dunnock, Western Yellow Wagtail and Common Chaffinch have been seen between 51% and 84% down average. Most of the common waders show better results. Bar-tailed Godwit, Ruddy Turnstone, Red Knot, Sanderling, Purple Sandpiper, Common Snipe, Green Sandpiper, Common Redshank, Wood Sandpiper and Common Greenshank have been seen with numbers above average. Whimbrel, Curlew and Black-tailed Godwit have shown records numbers since 1990. Other species though, have been poor such as Lapwing, Grey Plover and Dunlin. It is worth to mention that Lapwing (which has shown a very strong decline since 2008 in the observatory area) was registered in higher numbers in autumn 2022 than in the 6 years before. In autumn 2024, a total of 449 Lapwings were seen in the area, which is the second-best number since 2017 (first was 2022). There has been a good number of unusual species in the area during the autumn. We have registered Ross’s Gull (1st), Sabine´s Gull, Mediterranean Gull, Balearic Shearwater, Little Egret, White-backed Woodpecker, Yellow-browed Warbler (record number), Common Firecrest, Rose-coloured Starling, Siberian Stonechat, Citrine Wagtail and Two-barred Crossbill. The Ross’s Gull is the fourth record for Adger county. Ruben van der Horst (Netherlands), Michael McMullan (Ireland), Jan Erik Røer (Norway) and Gunnar Gundersen (Norway) have been volunteers at the station and helped the ringers (Benito Sánchez, David Santos, Torborg Berge, Aïda López, Landelin Winter and Christina Ninou), on the fieldwork in autumn 2024. | |||||||
