Bobolink in Canon City

I found at least one male Bobolink in Canon City this week. This is in a hay field (both grass and alfalfa mix) where Bobolinks have nested in the past but not for several years (also have Dickcissel, in next post). I have only seen one male up singing at a time so not sure if only one male but unlikely very many. I believe the female(s) is on the nest as there is only intermittent singing. In fact much of the singing is being done from a bird perched on the vegetation in the field as shown by the photo below. SeEtta
