Every spring as soon as the ice is out the loons return to the lake near our house. A mating pair frequents the cove near us. I welcome hearing the occasional exchange of haunting wails as the loons locate one another, or the male’s powerful yodel as he claims his territory (most often in response to a perceived challenge from a low-flying airplane). But it is not until the new generation begins to come along in mid-June or early July, that I hear the loons’ full voice, including the fluttering tremolo, an alarm cry that any parent loon will use if it senses a danger to its eggs or chicks. The tremolo can be a soft, quick flutter, but loons are famous for their resonant, full-throated rendition of this cry, especially when made by a pair late on a summer night. This wild and beautiful assault on the ears is in fact a likely indication that the loons are in a state of great alarm about something. I always worry for their babies when I hear it. Some years, the loon pair appears on the lake transporting or shepherding two chicks, but, sadly I have yet to encounter a season when both babies survive until fall.
Loons swim in all weather; they seem unconcerned by choppy water and waves. While I enjoy oberving loons anytime, I particularly love watching them glide through calm water. Yesterday as the rain lifted the lake was particularly still. The mist and low-hanging clouds gave a sense of intimacy to the loon family, a parent and child duo that was eventually joined, with a small flutter of excitement, by the other parent.
only a loon’s cry ripples,
downy chick swims close
