Eve posted a video yesterday of Polly trying to take over incubation duties from Spirit. But although she tried, she just could not see to get the knack of it: she was up and down, then circling the eggs, then touching them, then trying again to sit properly on them, all to no avail. I am not sure about whether or not Polly is all there; she just does not seem to have a natural instinct about this whole process, or peregrine life, for that matter. I do hope things work out well for her.
