As of March 5th the hawks still have not laid their first egg. Again, no cause for concern. The onset of egg laying in red-tails can vary extensively from year to year. The weather has been intermittently awful and that may affect the timing.It is hailing up at Audubon in Forest Park.
Since the Raptor Cam Red-tails took up residence in 2007, the dates they have laid their first eggs have ranged from March 3rd to March 16th. Last year with similar weather conditions, they laid their first egg on March 12. Some raptor species are already well into their nesting cycle--Great horned owls lay eggs as early as January. Other species like osprey have not even returned yet on their spring migration. In the Metro region we get red tails laying eggs as early as March and as late as April.
The Raptor Cam Red-tails continue to add to the nest ---There is a bunch of new material from the past few days. It is still possible that they will chose a different site. A couple of years back they moved down a floor on the fire escape. However, given their continued focus on this nest, I remain optimistic.
Definitely write in and post if you see the hawks at the nest!
