Orca (Orcinus orca), also known as killer whale.

ORCA! We had to wait for more than a week to say the magic word but today was the day. While scanning for Bonaparte’s gull, Rasmus suddenly finds three breaching killer whales (two adult and a young one) moving steady towards northeast. All the counting was for a short while paused to observe the fantastic creatures for at least two minutes. Sea lions were also on the move today and at least 50, most likely Californian Sea Lions were seen moving north. The morning started with heavy fog so counting was reduced but good numbers of Loons and Common Murres were still seen. Counting time: 06:30-14:00. 41 seabird species counted. Weather: Limited visibility due to fog, less than 500 meter until 10:00 and good visibility for the rest of the day. Weak wind from northwest 5 ms (11mph).
