To answer a couple questions on this:

I sent photos of one of the scuds to Phil Pelliteri, of the UW Madison
Insect Diagnostic Lab, and he confirmed that they were scuds.

Also,  while I guess we'd  need to examine the robins' stomachs to confirm 
without a doubt,
it did appear that the robins were eating the scuds.  They  were standing at
the edge of a little stream and pecking along the water's edge.  They would
seem to close their beaks on something they got in the water.  Others would,
instead, pull out a bit of algae  and examine it a bit and then toss it
aside onto the snow.  I went over to the edge of the stream and pulled out a
bit of algae  (Chara sp.) and shook it over the snow and found  some little
grubs.  I took these home and on closer look I thought they were scuds, but 
wanted a
professional ID.  So my husband took photos which we sent by email to Phil,
who confirmed my identification.

Thanks for the responses to my email.
