Peregrine Observations 2003
by Elli Jilek, Jean Moore and Eric Tull
- June 16. Although the Peregrine Falcons have been around the campus and the nest ledge for close to two months now, they have not nested. There has often been one bird in attendance and sometimes two birds, but although some food-passing was observed a month or more ago, the birds do not appear to have formed a pair bond and mating does not appear to have occurred. We are not sure what has gone wrong, but there have been no eggs laid to date, and it is probably too late for any nesting to begin now.
Aug.4. A maintenance worker reported seeing an adult falcon on the Social
Aug. 20. Elli observed 3 falcons on campus, with one on the Library Tower,
and the other 2 on Social Sciences. No territorial disputes were seen, so it may
be guessed that several or all were 'passing through' the area. Possible 2
younger falcons were involved, as their colouring suggested fledglings.
Sept.13-20. Several observations by Elli of one or two falcons flying and
visiting several bldg. spots, mostly on the Social Sciences bldg.
It appears that this year is a non-productive one. The reasons may be that
there were juveniles involved, or that the construction activity may have
impaired the natural activity needed for reproduction. This is the first time
since 1995 that we have not had any eggs or young.
