Hi Tweeters,

There's a *Slaty-backed Gull*, an adult in basic plumage in a large gull
flock on the S side of Hwy 10 about 2 km E of the Hwy 10-Hwy 99 interchange
in S Delta. This would put it in the vicinity of 104th or 112th Sts.

This bird is likely feeding in the Vancouver Landfill (to which birders are
emphatically *not* invited by the landfill staff and management!) and then
joining the large standing roosts in the fields surrounding the landfill.
The location of these roosts may change daily, so best thing is to cruise
the numbered streets N & S of Hwy 10 from 64th St E to 112th.
