My world gets turned topsy-turvy each year when the first chick hatches. Each year at this time most pairs are struggling just to hold their territories, find safe nesting sites, lay eggs, and fight off the black flies that chew on them. Today, for example, I visited four established pairs that had built nests and laid eggs, but only one — I am proud to say it is the pair on our home lake, Currie — is still incubating the eggs. The others had abandoned their nests owing to black fly infestation. Four lakes is too few to draw conclusions, but my findings today illustrate the debacle produced by black flies again this year. I am just not quite sure how to reconcile the carnage I saw today on my circuit of lakes with the engaging photo that Linda Grenzer took of the Jersey City male alertly guarding his chick.
I suppose the clearest message sent by the news of a successful hatch is that the world is varied and bright spots remain. Indeed, many loon pairs are beating the black flies and thriving. In fact, a few dozen pairs will follow JCF’s lead and hatch young in the next week or two. Moreover, most pairs that have fallen victim to black flies will lay a second clutch of eggs shortly; there is still ample time to hatch and rear young that can migrate south in November. So do not worry if the loons on your lake are swimming distractedly about right now instead of sitting on eggs. They will likely get back to it soon. In the meantime, take heart — as I am trying to — in the photo above.
