In 2009, the first egg came on March 9. Last year, it was March 13, delayed perhaps by the extraordinarily harsh winter.
I asked John Blakeman what he thought about this year:
"Right now, I think it's a bit early, particularly with severity of the passing winter. She may still be building up nutrient reserves from which to draw upon when the first egg forms in the fallopian tube. That could still be a week or two away. If I'm standing there with a scope, I can tell when the formel becomes a bit lethargic as eggs begin to form. But I don't get to watch her out on the Parkway. Others may be able to see these pre-egg behavioral nuances, especially women who have been pregnant and have a personal understanding of the matter. We men can be a bit clueless."
Last year, John expanded on this topic for us, and I will reprise it here:
"Here's one thing that viewers can watch for. The formel, when the big egg really starts to form and descend down her one fallopian tube (mammals have two of these; birds have one, so that they don't have to fly around with unused extra weight), the hawk will take on a somewhat stiff and concerned "look." She will not be as active and will just sit there for long periods, looking a bit dazed.
