Peregrine falcon egg

Mary Hennen, who has run the Chicago Peregrine Program for over two decades, was out and about today monitoring several wild peregrine falcon nests in the downtown area. When she got back to the lab she had with her a clutch of three eggs from a nest on South Wacker. The nest, and its eggs, were abandoned after the male of the pair was killed in a fight with another peregrine last week. When this happens, Mary explained, if it’s early enough in the nesting season and the eggs aren’t very far along in incubation, the partner that’s left will often cut their losses and find a new mate with whom to try again. I guess it’s hard being a single parent, no matter what species you belong to.

More on the city’s peregrines at this wonderful blog I discovered today. Stephanie Ware, a Field museum staff member and volunteer falcon watcher, writes the updates.

  1. It’s interesting how different species approach the task of raising their young. Some require both parents, while others opt (or settle) for single parenthood. I wonder why that is.
