I have had a link to the Ellis Bird Farm web cam which is focused on a great horned owl nest. The first egg has hatched! Someone was watching and saw a little owlet. Owls lay eggs every couple of days and start incubating when the first egg is laid. There is a wide variation in size of owlets on the nest and in hard times the youngest ones may starve to death.
So for the next while there should be more to watch than just the female sitting tight on the nest. The owlets will be in the nest for a long time before they fledge so there's lots more to see.
