Curlews over Rantamo

I haven´t seen so many Curlews at one time as now at Rantamo. I´ve used to see one at time but now is the migrant time, a flock of curlews was staying here. I was wandering what black something they have on their beak, perhaps mud.

Nice golden sunrise today, but day was windy, rainy and cold, getting milder to evening again. But all the rain is good for this season.
