In area of open space area where a number of exotic plants seem to have been planted and are naturalized.
Seems early for flowering.
Unusual to see lilacs blooming in late November.
Three Ospreys were together with at least one vocalizing. Heard them earlier in the day at nearby Arana Gulch. The previous week heard an Osprey vocalizing by SF Bay and observed one flying around a second one carrying something, possibly a fish, with legs extended.
