LOCALITY OF OBSERVATION
The bird was observed at Fort Boise Wildlife Management Area in Canyon County along Old Fort Boise Road. Specifically at: 43.8208, -117.0142.
HABITAT WHERE THE BIRD WAS OBSERVED
The bird was observed at the very top of a tree at the edge of a Russian Olive-riparian dominated forest that bordered a large weedy field.
SIGHTING DURATION, CONDITIONS, and EQUIPMENT USED
I observed the bird for about 10 minutes at a distance of approx. 30 meters with 10x42 Vortex binoculars. It was perched atop a tree with the sun mostly behind me. I was a very hot day, no breeze, and 0% cloud cover.
DID YOU TAKE NOTES?
Yes, later the same day
DID YOU CONSULT A FIELD GUIDE OR OTHER REFERENCE WORK?
No, not at all
WHICH GUIDE(S) OR REFERENCE(S): DID YOU CONSULT?
None.
DESCRIPTION OF THE BIRD(s)
Copied directly from Ebird notes:
One adult male was observed singing in the top of a tree. Identified by continuous warbling-type song, its size, uniform dark blue color, dark rufous wing bars, large beak, and long tail with white spotted undertail coverts.
BEHAVIOR OF THE BIRD(s)
I first heard the bird singing and observed it atop a tree. It sang for about 10 minutes and left the perch. It left the perch when I was putting my sound recording equipment together, so I did not see where it went.
HOW AND WHEN DID YOU POSITIVELY IDENTIFY THE BIRD, AND WHAT CLINCHED THE IDENTIFICATION FOR YOU?
The song clinched the identification for me, however, seeing the dark blue body, large beak, rufous wing bars, and long tail with white spotted undertail coverts played a role in the identification process.
HOW DID YOU ELIMINATE SIMILAR SPECIES? WHAT WERE THEY?
The most similar species include the male Indigo Buntings that were currently being seen in the area and Lazuli Buntings. Lazuli Buntings were readily ruled out by the grosbeak's song, uniform dark blue coloration and large beak alone. Indigo Buntings were ruled out by the grosbeak's song, uniform dark blue coloration (not fading from darker blue above to paler blue below), long tail, and large beak.
WHAT IS YOUR EXPERIENCE WITH THIS (AND SIMILAR) SPECIES?
Intermediate. I have observed and heard several male Blue Grosbeaks in southern Idaho.
DESCRIBE YOUR GENERAL BIRDING EXPERIENCE
Extensive. I have been avidly birding for the last 10 years, mostly in the Intermountain West.
