På avstand blir nøtteskrikene noen flaksende prikker på himmelen. Høsten er fortsatt ung, og tidligere invasjoner av nøtteskrike har pågått til langt ut i oktober. Som denne grafen viser har det aldri tidligere vært i nærheten av årets antall observerte nøtteskriker frem til midten av september. If you have been to the western part of the Lista peninsula in the recent weeks, you should have noticed that the Jay (Garrulus glandarius) occurs in large numbers. Flocks of different sizes are constantly trying to migrate from the lighthouse area, and the daily numbers of migrating birds as well as ringed birds are higher than ever before. By Jonas Langbråten Jay is a species that is usually not seen very often at Lista Bird Observatory. There was only one observation of the species throughout 2013. Some years, however, we record invasions. In 2012, there was some invasion tendencies in late September / early October, with a daily count of 120 Jays on October 1 as the highest number. In 2007, there were also high number of Jays during autumn, with 208 Jays on September 21 as the highest number. However, we must go back to 2005 to find the last really big invasion of Jays at Lista Bird Observatory. That time the invasion lasted for several weeks through September and October, with nine days with three-digit number Jays logged. On September 21, 2005, the until now daily record of Jays at Lista Bird Observatory (600) was logged. The same day, 12 Jays also got ringed. This year the invasion began on August 27, when 53 Jays were recorded. During the first days of September, small flocks of Jays was seen daily, before it really started to reach large numbers by the 10th of September when 426 individuals were recorded. The following day the number had increased to 570. The same day we ringed as many as 23 Jays, wich is the highest number of this species ever ringed in one day. On 13 September, the record from 2005 was beaten, when 640 Jays were recorded. Also the following days have had three-digit numbers of Jays. Where all the Jays come from we do not know for sure, but we assume that they have an eastern origin. Most Jays that reach Lista Lighthouse makes a turn over Gunnarshaug, and returns to the forest in Lebeltet and continues towards northwest. At the moment there are still a lot of Jays in the area, so the invasion is still going on.
