I have the same report as of Tuesday afternoon, no activity yet I am expecting to see them feeding chicks soon, we shouldn't be able to see bobbing heads for a few weeks I think the nest is too deep for that and the angle is too steep. But the last day according to my calculations for incubation time was yesterday, so any day now.
