I visited the Astoria Park nest this past Thursday evening to find that Athena is indeed now incubating eggs. Atlas returned to the nest at around 5pm with a Starling in talons for Athena. She began to eat the Starling right there in the nest, so Atlas decided to perch nearby and clean his beak. Athena then left the nest with the Starling and continued to eat her meal on a tree near the tennis court. Atlas realized this a minute or so later and returned to the nest and sat down on the eggs. For a minute there neither of the pair were sitting on the eggs which made me think that eggs had not yet been laid, but Atlas quickly realized he needed to return to the nest and he disappeared into the deep bowl while Athena finished her meal. From watching this pair in 2008 I realized Athena is a superior hunter and often passes leftovers to Atlas. She also spent more time hunting during the egg incubation period, leaving Atlas to do the incubating. I don't know if this is do to Athena being the older/more experienced of the pair, and if that role reversal will change as Atlas matures. Hopefully watching the nest this year will shed some light on the situation.
