Sea mammal bones on the beach

Morning observations:

Today I had some company of a harbour seal “Spættet Sæl” at the morning observations. It was playing in the water by the shoreline, which was nice to see. At the first hour of the observation, there were not that many birds. After that is was a nice amount of migrating birds, but the last hour was also not that many. Around 09:00 I went back to the station.

Todays observations can be seen here.

In the afternoon I went for a little walk on the beach where I found two bones! One is probably from the spine from a marine mammal, probably a porpoise “marsvin”. The other one looks like a jawbone. We asked some specialist if they can determine for us, so we can be sure from what species it is.

The ringing:

DMI showed 8 m/s for this morning but it felt like it was more. During the morning it slowed down a bit. I did not have so many nets open and they did not catch so many birds, it was mainly Blackbirds “Solsort”, most of them females.

On the way down from the station garden I found a quite chunky Common Frog “Butsnudet frø”, which was a welcome change on a slow morning.

In the afternoon, Joseph came back to the station from Copenhagen and while we had dinner, Svend Aage, Bent, John and Svend had a meeting.
