I was at that same game last Sunday and added two birds to my
(ball)yard list: swan sp. (sorry, flying too high to call) and
Red-tailed Hawk. That makes eleven, with nine previously seen: Bald
Eagle, California Gull, Glaucous-winged Gull, Rock Dove, American
Crow, Violet-green Swallow, Barn Swallow, European Starling, and
House Sparrow.

What are your ten, Alan? Anybody else?

I don't count birds seen from the terraces looking out away from the
stadium -- only those within the footprint of the stadium or visible
in the sky from field level. You could get up there on the third
level terrace overlooking Elliott Bay and really pick 'em off if
they'd let you bring a scope and tripod into the park.
