More like one bird per 210 nameplate kW. It was already pointed out by the grandparent comment that cats are a bigger problem for birds in general. But still, wind turbines kill enough eagles and other larger birds for it to be a significant concern deserving of mitigation.

E.g. the estimate is that the Altamont Pass installation kills ~440 burrowing owls per year, when there's likely to be fewer than 10k breeding pairs of owls left. That's a 2% kill rate (or more, counting the disruption to breeding pairs) from one (larger) installation.
