Hummingbirds ID - Las Vegas/Henderson (1 Viewer)

[Pedro Maia]

I hope someone can help with some hummingbirds ID, pictures taken last week at Henderson Bird Viewing Preserve and Clark County Wetlands Park, I´m not familiar with hummingbirds, with the exception of on individual photographed in a feeder pictures were taken from some distance and with poor light and I found that Anna´s and Costa´s can be very difficult to tell apart if pictures aren´t good, which is the case, I don´t know if a positive ID is possible for all.

1 - The only reasonable pictures, I more or less certain it´s Anna´s





Now I´m just guessing

2 - Costa´s?







3 - Anna´s?





4 - Anna´s?







5 - Anna´s?

1,3,4,5 I believe these are all Anna's, they show a pinkish red head which points to Anna's. Costa's tend to show more purple in the head.
2 is most likely a female Anna's as well.

Regarding number 2, with all limitations of the pictures I think the bird lacks the "stain" in the throat and has a grayish cheeck patch, that´s why I thought of Costa´s, what do you think?

despite the photographs' restrictions, I believe the bird has a greyish cheeck patch and lacks the "stain" in the throat, which is why I thought of Costa's. What do you think?

Yes, I can see that the throat appears to be lacking the "stain" which would point to a Costa's. Female hummingbirds can really be tough to ID.
So, yes this could be a Costa's. Thanks for the input and posting.
