I think the bittern was always relatively rare here, at the edge of its range. Likewise the sandpiper.
Many species have significant expansions and withdrawals. For example, Gray Catbird. During some periods they are local breeders in most of the northeastern quadrant of Oregon, reaching the Cascades; during scarce times they seem to withdraw to the eastern part of the Blue Mountains.

Regarding Upland Sandpiper, one has to wonder why they died out in Oregon with apparently plenty of adequate habitat? I understand that the colonies in Washington died out before those did in Oregon. Regarding Least Bittern, one may wonder the same thing as well - with an abundance of breeding habitat, why are they gone (or at the least died way back)? One theory I heard for the sandpiper was that changes in its wintering grounds were the most likely factor. The bittern's dissppearence seems more of a mystery. Any thoughts?
