Ivasiva arter kommer mer tungt v\u00e4llande och \u00f6vertar permanent nischer som kan vara lediga, men de kan ocks\u00e5 tr\u00e4nga ut andra arter. En del blir kontroversiella som nu senast Nilg\u00e5s.<\/strong> Tom en del “djurv\u00e4nner” appl\u00e5derar d\u00f6dspatrullerna som rycker ut.<\/p>\n\n\n\n Tv\u00e5 arter har i\u00e5r slagit till p\u00e5 \u00f6n med ett viktigt landm\u00e4rke, konstaterad h\u00e4ckning, Kornsparv och Busks\u00e5ngare.<\/strong> \u00c5tminstone den sistn\u00e4mnda \u00e4r nog tidigare f\u00f6rbisedd.

Vitkindade g\u00e4ss<\/strong> startade sin invasion i Sverige p\u00e5 Gotland.<\/p>\n\n\n\n S\u00e5 var det med \u00c4gretth\u00e4gern<\/strong>, Gotland f\u00f6rsta svenska h\u00e4ckplatsen. F\u00f6rsta obsen p\u00e5 Gotland i mitten av 80-talet. Nu talrik h\u00e4ckare och vi v\u00e4ntar bara p\u00e5 f\u00f6rsta kullen i Paviken eller i h\u00e4gerkolonin vid Varvsholm.<\/p>\n\n\n\n H\u00e4rlig syn. Har ocks\u00e5 roat mig med litet nattsudd. Faktiskt lyckats med 5 planeter under en natt, om \u00e4n inte samtidigt. <\/p>\n\n\n\n Jupiter och Saturnus<\/strong> ses tidig natt i S n\u00e4ra varandra. Jupiter<\/strong> stor och sj\u00e4lvlysande med flera m\u00e5nar. Saturnus<\/strong> strax \u00f6ster om Jupiter<\/strong>, med ringar.

Tidigare under natten och helst tidigare i Augusti har den svagare Merkurius<\/strong> kunnat f\u00e5ngas in snett ned till v\u00e4nster strax \u00f6ver tr\u00e4dtopparna. Ocks\u00e5 tidigare under natten har den r\u00f6daktigt lysande krigsguden Mars marscherat s\u00f6derut framf\u00f6r Venus<\/strong>. Kameran \u00e4r riktad mot ONO. H\u00e4r har ocks\u00e5 fladdrat ett tiotal fladderm\u00f6ss,<\/strong> om\u00f6jliga att f\u00e5 p\u00e5 bild. Men av \u00e5tminstone tv\u00e5 arter.
