At another nest in Montréal (Jacques-Cartier bridge) a juvenile from last year is still at the site and is interfering with the current nidification, as shown in this video: https://youtu.be/BEpZ7mvmLM8 (in addition, immediately after the juvenile left the nest box she tried to steal the meal from one of the adults). The adults show no sign of trying to drive her out of the territory. To be exact, this juvenile is not a natural daughter from the pair; instead, she was adopted by the pair after being released near the nest on June 30, 2022 together with one of their natural daughters.

This was the first year in over than 10 years that young peregrine falcons flew from one of the nesting boxes on this site, so this pair is probably facing such a situation for the first time. In the only other case in Montreal of an interference by a previous year juvenile that I know (University of Montreal, 2010), it was the first time that the pair successfully raised younglings the previous year. Perhaps the peregrine confronted with this experience are learning in the hard way to not tolerate anymore juveniles of the previous year, which leads to the following question: are there known cases where a pair tolerated a juvenile from the previous year in more than one nesting season?

One of the many press reports about the laying of 4 eggs at the University of Montreal nest: ''Viewers can't get enough of this 24/7 falcon nest cam at Université de Montréal'', CBC, April 29, 2023

You are talking about Polly, right. She had an injured leg if I remember and then went on to get her own site.. adults are more tolerant of youngsters. I see this more and more but after awhile they are moved on .
