Cascadia Hummingbird Report - 4/17 to 5/01

The northern most report of RUFOUS HUMMINGBIRD is now
Cordova, AK from 4/27 (60.5428N 145.7575W). It is also the
western most report. Reports continue to fill in spots
throughout interior British Columbia (thanks to Wayne
Weber for forwarding reports). Nesting birds were
reported from Nisqually, WA and gravid females were captured
in Victoria, BC. First detection reports follow, except
as noted

4/17 Victoria, BC (gravid female)
4/18 Giscombe, BC
4/19 Quesnel, BC
4/19 Upper Hat Creek, BC
4/21 Nisqually, WA (on nest)
4/24 Merritt, BC
4/22 Castlegar, BC
4/24 Kootenay Lake, BC

Curiously, there have been no interior reports from Oregon
or Washington. Lanny Chamber's map (see below) shows
multiple reports from Idaho in mid-April, but there are no
reports from the Great Basin... hmmm.

CALLIOPE HUMMINGBIRD reports continue from throughout the
Cascadia Region including displaying males at Sisters, OR.

A BLACK-CHINNED HUMMINGBIRD arrived at Fields, OR on 4/29.

The most intriguing news are three different reports of
COSTA'S HUMMINGBIRD. A well described and photographed
bird was at an Astoria, OR feeder on 4/20 to 4/21. It may
still be around, but is on private property. A COSTA'S
turned up at Brackendale, BC on 4/27 and another at
Richmond Beach, WA on 4/29. Is this the front end of a
range expansion or a singular anomaly? Time will tell.

Mike Patterson Alas, to wear the mantle of Galileo,
Astoria, OR it is not enough to be persecuted
celata at pacifier.com by an unkind establishment,
you must also be right.
