Rose-breasted Grosbeak at Boyce Thompson Arboretum

This is a follow up to yesterday’s post of the Orchard Oriole at Boyce Thompson Arboretum. Seen in the same tree with the oriole was this vagrant immature male Rose-breasted Grosbeak. I wasn’t as lucky with the grosbeak as I was with the oriole in terms clean and close composition, and had to settle for these not-so-pretty documentation shots.

I did get lucky though with this shot that shows the diagnostic red feathers under the wing: the best field mark to separate this species from the very similar Black-headed Grosbeak that is its western counterpart and the expected species here in AZ.

I suspect that every photographer has experienced something similar – you’ve just lined up on the subject and depressed the shutter release only to have the subject move at that exact instant. Normally this results in an instantly deleted reject, but in this case it showed an important feature that I could never have captured intensionally.

Both images: 11/19/2012, Nikon D300, Nikkor 300/2.8 AF-S plus TC20E III (2x), Gitzo tripod, ISO 800, f/8. Top photo: 24% of frame; bottom image 12% of frame.
