One of my favourite summer birds in Ontario is the bobolink, generally found in native grasslands.  Bobolink numbers have decreased substantially over the last fifty years, and it is a bird of special concern to a number of conservation groups. I first heard of the bobolink in my days with Rio Tinto, which has an association with Birdlife International . At the time, I was doing work in Paraguay. The bobolink migrates between Argentina and Paraguay and grasslands of Canada and the northern United States. A farming friend in Kentucky reports that he sees the bobolink on his farm, on migration within one day of the same day, each year.  In 2017, we saw about 200 in a flock on a levee of the Mississippi River in Western Kentucky.  Exactly one year earlier, another observer reported on eBird seeing about the same number at the same location.
