In the last two years I hadn't seen them in this part of Tejo (Tagus) river. But, this year, it seems that they decided to come back and stay for a while.

This time, there were about a hundred of them! They usually stay in the middle of the river, where they feel safe...
But this time a bunch of them came rather near me.
I hope they stay with us a few more days:)

These photos were taken with my new Fuji Finepix S8000fd.
