Not long. There was about a hundred or more of these that landed in the trees near where I was photographing. Got tons of shots. The difficult part was deciding where to shoot as there was so many of them. Then they all flew off at once. They were there for about 20 minutes or so.

Thanks Anna. I used my Canon R5 for this shot, paired with the Canon 100-400mm EF L lens with extender.

Thank you.
