Hummingbird Movement Report 04/3 to 04/10

Rufous Hummingbirds arrived in Alaska last week and when
one connects all the dots for coastal first detections,
the line is pretty straight.

CALLIOPE HUMMINGBIRDS were reported from Washougal, WA on 4/4
and Corvallis, OR on 4/5. A COSTA'S HUMMINGBIRD was seen at
the Rose Garden in Portland, OR. There are only a handful of
Costa's reports from western Oregon, but the species is now
annual in Grants Pass and Bend. This may be an indicator of
further range expansion.

A likely ALLEN'S HUMMINGBIRD was observed in Grants Pass, OR
(though green-backed Rufous cannot be categorically eliminated)
on 4/9. This is an extreme eastern record for the state.

Rufous Hummingbirds at the Neawanna Wetland Preserve were
observed actively nectaring on Black Twinberry (Lonicera
involucrata), but it is becoming clear that Hookers Willow
(Salix hookeriana) is the important early forage species for
hummingbirds on the North Coast of Oregon.

At least two ANNA'S HUMMINGBIRDS are still regularly at my
feeder, but Rufous Hummingbird numbers have dropped.

you must also be right.
