This is an unusual nest site, since the resident pair, who are both unbanded, adopted a planter on someone's balcony as their home.
Last year, this pair attempted to nest at three different sites. They laid one egg at each of the first two sites, and then laid two eggs at the Belmont Addison site. The eggs were incubated for a while, and then abandoned.
This year, they returned to Belmont Addison and laid four eggs. The eggs were incubated, and all four hatched. This is a very small planter for four growing peregrine chicks. Fortunately, the people who live there, and their neighbours, like the birds.
On May 27:
The webcam has been somewhat up and down, and at the moment is off air. I hope it will be back, and that everything is okay with this falcon family.
