The Rufous numbers picked up yesterday at our place north of Grants
Pass. Heard a male displaying. First female Rufous seen too.

Based on past migration observations, I think those most likely
explanation for the lag in migration is the sagging jet-stream
which creates poor conditions for movements by putting a weather
barrier in Northern California rather than the more typical late-
winter to early-spring position closer to British Columbia.
This has, in the past, produced a dense and very rapid movement
pattern which can be quite spectacular in places.
I checked one of my favorite patches this morning in Warrenton and
found that the Salmonberry blooms are late this season (we've
only seen temperature break 45F in the last 4-5 days), but the
willows are blooming on time.
If you've never seen dozens of hummingbirds on the move in one place,
this will be the year, assuming you can put yourself in the right place
at the right time.
