Again, this is Syngamus trachea/gapeworm. I don't know why the site doesn't have it. The adult form is easily visible in the trachea of nestling birds who are infected. This is an egg about to hatch; he was squirming about.
This was from wild Canada Goose poop so it should count; I ran the fecal, sorry for the terrible quality pic... I had to take a picture of the computer screen hooked up to the scope. This is 100x magnification.
I'll try to convert the good .bmp picture to .jpg so I can use it.
