There were 14 in total. This is the most I've seen at the Reifel Migratory Bird Sanctuary, but I only visit six or so times a year; perhaps this is unremarkable. Some Sandhill Cranes overwinter at the sanctuary, so at any time of year one might expect to spot at least a few. I haven't been keeping tabs on breeding success of the residents, so can't discount the number being due to reproductive increase. Some of the birds appeared to hatch-years (rusty-backed), but I don't know who is resident and who might be passing through. All these thoughts in my head. Heck, head, just look at the birds.
Note the large bands high up on both legs of the central bird in the second image. Someone is keeping track of something.
