I too saw those eagles over my house in Steveston. There may have been more than 7. Lots of eagles nests around Richmond too, with some having excellent views for photography and viewing the chicks.
I too have seen all the wildlife varieties you have mentioned. I see deer and coyotes from time to time in the area off #6 road on my way to work, but I know they are also sometmes present in the farmland south of Steveston highway.
Just too add to your list I would include otters and beaver. A few months back while at Gary Point a beaver climbed out of the slough at Gary Point onto the trail a few feet ahead of me. Scared the heck out of me - those things are a lot bigger than you would expect! I've also seen beavers swimming in the Fraser itself. The otters I saw were in the larger sloughs (ditches) in East Richmond.
When I was a kid in Richmond many years ago there were occasional reports of a black bear coming into the blueberry fields. I guess they came over from burns bog in delaa. I don't think that happens anymore though.
