I have seen quite a few large flocks of Canadian Geese migrating around Chicago lately. From what I have read they were "large birds." Other than geese, I'd guess they could have also have been cormorants, although I'm not sure if cormorants flock together when migrating. Are there other large birds that flock together and are currently migrating through the Chicago area now?
As far as engine damage, other than someone from UAL chiming in, we'd have to guess that one engine was pretty much destroyed, and the other one, which IIRC may have only ingested one bird, was in a repairable condition.
What scares me is that they could have just as easily lost both engines. And with a full load of fuel for the flight to San Paulo, things could have been pretty disastrous.

The Canada Geese are indeed migrating in the Chicago area at this time. My question about the types of birds are due to the fact migrating birds are normally on the ground at night. It is interesting to watch them come up from the south, circle the area that was the south tip of Lake Michigan 10,000 years ago and then head west.

Quoting BravoGolf (Reply 5): My question about the types of birds are due to the fact migrating birds are normally on the ground at night.
Actually I think you'll find that most of the migration does happen at night. Some people think its because most of the birds predators are active at night, not during the day. I did a really quick search and found this:
"...but great numbers of these birds also pass through at night; the calls of Canada Geese or the conversational gabbling of flocks of ducks are common night sounds in spring and fall in many parts of the country. Observations made with telescopes focused on the full moon have shown processions of birds, and one observer estimated thier passage over his area at the rate of 9,000 per hour. This gives some indication of the numbers of birds in the air at night during migratory peaks. Radar observations have shown that nocturnal migration begins about an hour after sundown, reaches a maximum shortly before midnight, and then gradually declines until daybreak. Bird echoes during peak migration periods may cover a radar screen."
I'm also pretty sure that the FAA is in the process of installing or updating radar specifically to find migrating birds in and around airports across the country, especially at night where you can't see them in your flight path.
It sounds like you're located in the southern Chicago area. You may be interested in visiting the Jasper-Pulaski Fish & Wildlife Area in Medarville, IN, to see the huge flocks of sandhill cranes, sometimes numbering 30,000 birds, that make their way through our area. Worth the visit in the fall for a different sort of "spotting."
