Common Nighthawks Migrating
Nightjars, or “goatsuckers” as some call them, are a family of birds that catch and eat insects on the wing, are often ground nesters, and many (whip-poor-will, for instance) have distinctive calls. Nighthawks are a member of this group, but not a very well-named member, as they are unrelated to hawks and are active at dawn and dusk (not night). This insect-eating bird is often seen on the wing, hawking insects in both rural and urban areas (Fenway Park comes to mind). Its loud, nasal “peent” calls and bat-like flight make this bird very noticeable if it is feeding. We are currently at the peak of the fall Common Nighthawk migration from North to South America. Flocks of hundreds and sometimes thousands are seen flying overhead, often in the early evening.
Unfortunately, in the past 30 years the breeding population of Common Nighthawks in Vermont has declined by 91%, according to the most recent Vermont Breeding Bird Atlas, and this drop in population is not limited to Vermont – much of Canada, New England and beyond has experienced a 50% – 70% decline. Increased predation, indiscriminate use of pesticides leading to lowered insect numbers and habitat loss may have played a part in this drop. (Photo from public domain.)
