Jim, some years ago the entire roadside from East 90 to West 90 was in grasses and weeds and always had harriers and owls, but then they plowed most of the fields on the south side of the road.That got rid of the voles and their predators. The north side of
the road still seems to have appropriate habitat, but perhaps it?s not. Also, there have been some floods that probably eliminated a lot of the voles (they were all over the road during one of them). It is impressive that whatever the vole population is, it?s
large enough to support all those raptors. But voles multiply at a high rate.<br>
<br>
Rough-legged Hawks have all but disappeared from the Skagit County farmlands, and I don?t know how much of that is due to vole decline and how much to climate change. Northern Shrikes used to be fairly common in that area, but they too have disappeared, and
perhaps neither of those species is wintering as far south as they used to. Same thing, of course, for Snowy Owls.<br>
