This is an exact duplicate of a photo on IBird of a female Black chinned,
The photo you found on iBird is the photo that is being questioned. The
observer thought it was a Broad-billed, which we agree it is not. I am
thinking Costa's, not Black-chinned.
The original bird is the center for both of these comparisons.
The first series compares to Black-chinned, the second compares to Costa's.
I was hoping that over time someone would pipe in.
Just as an FYI, I was given permission to review the picture.
It is disappointing that someone would call out a copyright violation.
Simple research would have shown that critique of work is a valid use.
My original posting does not violate copyright law even without the
permission that I received.
Never, never accept everything you see just because it is on a reputable
website. With that type of approach, a mistake will never be corrected.
I didn’t call out a copyright violation, I said ————
“As an aside if the photo is copyrighted to a person you should state that in your original post of the photo.”
And unless given permission by the photographer I will stand by this. I didn’t say it was in violation of the law. But I still feel credit should be given.
So let's see if I understand this....
I stated the picture was not mine
Although allowed, one should not critique a photo without throwing the photographer under the bus
When a person asks for help with an ID, a moderator with 28,000 posts can weigh in by simply comparing it to another photo
When a moderator provides incorrect information, as was done above, it is not corrected '"When reading a description of the Costa’s there is no mention of the white on the bottom of the tail feathers".
A rudimentary review of Costa's in Sibley, Williamson's Hummingbirds, Howell's Hummingbirds all indicate white on the female tail. Any knowledgeable person would know that all but two of our western hummers have white on female tails. A picture of a female Costa's (taken by me) is attached.
A moderator mentioning the word copyright, is in fact not concerned with copyright law.
So in typical fashion, let's delete this thread as we only want to call out others mistakes, not our own.
