Dorothy has definitely not completed her clutch.
Peregrine falcons begin incubation — they cover the eggs continuously — when the female has laid her next-to-last egg.
Today before dawn Dorothy roosted near her eggs but did not cover them.
Does she expect to lay five eggs this year?
Only time will tell.
