It's been at least 30 days since the Riverside female started sitting on her nest with her second clutch. It's hard to figure out when she actually laid her eggs, since Red-tails often start sitting on their nests a few days before they start laying their eggs, so calculating the exact hatch date is difficult. However, it should be any day now.
On Saturday, it hadn't happened yet. No signs of a feeding, the mother leaving the nest alone for a few minutes, or an adoring pair of parents looking into the nest.
