Re: [cobirds] Hummingbird ID help, please DISREGARD

Please disregard my query.

The date stamps on these photos indicate that they were taken in Northern California, not Colorado. This bird is likely an Anna's Hummingbird, not a regular Boulder species.  I seem to have accidentally deleted the photos of the suspected Calliope that I took in Boulder.

My sincere apologies for the confusion.

Are the attached photos of an immature female Calliope Hummingbird? They were taken August 1st at the Boulder Community Gardens in north-central Boulder. The bird was noticeably very much smaller than the many Broad-taileds. It seemed closer in size to a large bee than to an adult Broad-tailed.

My hesitancy: Sibley shows immature Calliopes as having a thin white strip above the gape, which this bird doesn't show. The overall size was very tiny and the tail is shorter than the folder wings. Could this just be a slow-growing, small Broad-tailed with a short tail?

Thanks,
