![]() ![]() It jerks and twists, making sudden, choppy shifts of direction to snatch its prey. Swooping and diving through the air on its long slender wings, the nighthawk emerges at dusk to chase down aerial insects. The flight call of the Common Nighthawk vividly evokes a warm summer evening. Thundershowers last night.Written by Bob Sundstrom This is BirdNote. was 51 degrees early today, probably in the 60s during this recording. This juvenile's call starts at a lower pitch than the one recorded in the previous recording (the first of the four) and then downslurs. Adult call duration about 1.4 seconds juvenile call about half that. The two juveniles called at different pitches, but adult call was constant. Juvenile standing on nest of sticks had yellow legs and mostly white fuzzy head. Adult was light morph with reddish horizontal breast markings and broad white band on tail when it flew. Some marsh areas clear of most trees, with shrubs and Yellow Warblers and White-throated Sparrows. Boardwalk suggested this area frequently wetter than it was today. Forest was mixed conifer/deciduous, and quite dense. There were two juveniles present, one standing on the nest and another that was flying about over the forest canopy. It is possible the other adult was hunting for food for the juveniles.īoth birds were seen. The adult's persistent calling suggests teaching the offspring how to make the correct sound. I couldn't be sure which juvenile was calling because of the dense canopy, and it is possible that all juvenile voices on this recording were made by a single juvenile whose voice was changing like a human adolescent's. Then the higher pitched voice begins again and continues to the end of the recording. The lower pitched voice begins at that point and continues until 2:25. On this recording, one juvenile is calling with the adult from the beginning until about 40 seconds. ![]() Adult bird was perched sometimes, flying at other times while calling. This is the most interesting of the four recordings, because I think it has both juveniles' voices on it as well as the adult's. It is possible the other adult was hunting for food for the juveniles. This is the last of four recordings today of the Broad-winged Hawks. On this recording, adult call duration about about 1.6 seconds juvenile call about half that. ![]()
