Both the weather and the species composition of birds are reminiscent of early spring rather than late spring. Today in the cold wind we turned up a record...
In sharp contrast to yesterday, today was very quiet. Perhaps as expected, the first really calm clear night probably prompted many migrants to get a move on...
