Shorebirds:
The young Mute Swan from October 2017 had developed some aggressive behaviour running after cars in Sørevågen. It finally met its fate on the 11th when it was run over. A flock of 55 Pink-footed Geese migrated over the island on the 6th. Greylags have been present in large numbers throughout the month with over 75 birds, while young were noted at the end of the month. A pair of Shoveler alighted from the dam by Måkeskitt on the 27th, the most notable record of the month for this group, a Tufted Duck flew over Beiningen on the 16th is also noteworthy. A female Red-breasted Merganser in Tuevågen on the 27th is also worth a mention. Good and warm easterly winds were not ideal for seabird passage. Seven Red-throated Diver on the 25th, and 22 Red-throated Diver and a Great Northern Diver on the 27th were the most notable records.

A good day which put the other good finds in the shadows. A Firecrest was ringed in Merkeskogen on the 19th and was in the area until the 28th. A Shorelark performed well on the ploughed field of Håvard Nordvik on the east side of Veito. The same location also produced a Stock Dove between the 25th and 27th. Black Redstart were well represented with a male on the 7th, female-type on the 10th, followed by one to three birds between the 18th and 22nd. Hawfinch was also well reported with various birds reported throughout the month, with a flock of six birds on the 16th. Bullfinch are not regular either in the spring so a male on the 5th and 6th and two birds on the 17th in Herberg are noteworthy.
