John Lewis’ almost daily observations of a Peregrine family’s residence for
at least 8 days in Sycamore Canyon highlights a fascinating aspect of
Peregrine breeding biology that deserves greater attention. It appears
that parental care of offspring and their training does not end at the nest
site. We know this is the case with many species, but it’s interesting to
know that one aspect of the complex roles coastal habitats play in late
summer is to provide this ‘Continuing Ed’ program for Peregrines.
Beginning on July 7, John’s bike rides took him past Conejo Road where it
meets Sycamore Cyn. After recognizing that more than one PEFA was hanging
around, he photographed the birds and recognized their age
differences. Because
Peregrines are solitary when not at a breeding site, and because this is
not a breeding site, he was observing a family group still involved in
nurturing offspring. John will show me this area this afternoon—if this
family is still around, it will be at least Day 9 of their occupancy here!
