I don't recall a Bobolink record but there have been single reports of a
Least Flycatcher, a Sage Thrasher, and possibly nesting Vesper Sparrows
there over the years, plus it has had nesting harriers and kestrels,
apparently. It also has the greatest diversity of willow species of
anyplace I know of around here: at least S. lasiandra, S. sitchensis, S.
scouleri, S. piperi, S. mackenziana [I think], all along the marsh trail
loop. Oh yes, an nesting barn owls in the old windmill and sometime a
great horned pair nesting in the dense firs near the picnic area.
