Andrena male
Males of many Andrena species, such as A. imitatrix, fly in large numbers about the tips of tree branches in early spring. They are looking for females. A paper by S. Batra describes this behavior well.

 
Thank you!
You have a citation for the paper?

 
This one may be helpful:
Batra, S. W. T. 1990. Bionomics of a vernal solitary bee Andrena (Scrapteropsis) alleghaniensis Viereck in the Adirondacks of New York (Hymenoptera: Andrenidae). Journal of the Kansas Entomological Society 63:260–266.

Your image is not of A. alleghaniensis but it may be of A. imitatrix, which is in the same subgenus and behaves in a similar way.

 
Thanks again.
I am amazed at what I've found in my own back yard!
