Rooftop crow gatherings

For a long time, I've watched the neighborhood crows gather on the same cypress tree (https://www.inaturalist.org/observations/61228632). After each meeting, they fly far out into the Presidio and various parts of the city.

Recently, I start to notice them on our neighbors' rooftops:
1) when it was very foggy (https://www.inaturalist.org/observations/61754040) and
2) an hour before the rain (https://www.inaturalist.org/observations/65133231)

I wonder if they are checking on each other whenever there is a change of weather or sharing the locations of their food cache?

This evening, instead of meeting at their usual cypress tree (https://www.inaturalist.org/observations/61228632), they were gathered on the rooftops.
