Monday evening at 1705 hours I was sitting at the corner of Boniface and Northern Lights. I was over flown by a flock of about 20 mallards. Then a second flock of about the same number of birds came over. Then a third flock of about 10 birds came over. Then the light turned green and I had to make my left turn, but another flight was overhead of an undetermined number of birds. They all came out of the northeast. Every piece of water in that direction except for small sections of Westchester creek is solid.
While sitting there I could see them working around and then eveloping down about a block west of Boniface and two blocks south of NL. Each wave of birds went down in the same spot.
Google Maps tells me that the X is near College Gate Elemenary School or E 30th AVE and Lily St. Someone is laying out bait in their driveway. Corn fed birds if you can find where they spend their days.
We usually see these large flocks at this location in the spring, but something has them on the feed early.
